We have packed this website with useful information that will help you to make an informed decision regarding your choice of lubrication and filtration products for your vehicles and equipment.

Some of the most frequent questions people ask us about AMSOIL are, what is required in order to convert to AMSOIL, how long do I have to wait before installing AMSOIL in a new engine, and what can I expect to notice once converted to AMSOIL?. Here are our answers in a detailed explanation:

Converting a vehicle to AMSOIL synthetic oil is fairly simple, but there are a few things you need to be aware of. First, if you have a brand new vehicle we recommend that you run a short cycle of petroleum oil on a gas engine passenger car or light truck (typically 500 miles or up to the first scheduled oil change) and approximately 5000 miles on a diesel engine in such as a Ford Powerstroke or Dodge Cummins Turbo Diesel before installing AMSOIL. This doesn't mean that you can't install AMSOIL sooner, as many OEM's install synthetics as a factory fill (such as the Dodge Viper and Chevrolet Corvette), it simply means these are our recommendations based on our extensive engineering studies and knowledge of this topic. Today's modern engine manufacturing and materials technology is much more sophisticated than in years past. Regular gas engine passenger cars and light truck engines do not require the extensive break in process many people think they do. In addition, by the time you get your new vehicle the engine has already been through a series of hot tests also run on in-plant chassis rolls testers to check functionality of all systems and then driven around the plant and railhead in order to get the vehicle to the dealer, which also helps accelerate breaking in of the engine.

The engine break-in issue is the subject of much controversy as everyone seems to have their opinion on when an engine is considered fully broken in. The information we provide is based on the results of engineering studies as well as many years of experience and teardown analysis on test vehicles. The differences between a vehicle that was properly and fully broken in and one that was not can often be hard to detect, yet there are tell-tale signs of this but they are not easily detected except in all but the most extreme situations. The subject of what occurs during the break-in process can easily be the subject of a 100 page report therefore what we cover in this website page is only the essential points you need to know.

Breaking in an engine is a process of properly wearing-in the pistons/cylinders/rings, bearings, valves, camshaft, lifters, rockers, etc... In addition, part of the breaking in process is not only wearing-in and seating the internal engine components but also stress relieving the components as well. Crankshafts, connecting rods, pistons, blocks etc... have many stresses due to the casting or forging process, machining and welding process. We have viewed and measured these stresses, called fringes, using what is called lazer holography. These stresses are properly reduced/eliminated by costly and time consuming heat aging as well as shot peening and or high frequency vibration on a very specialized bedplate for an extended period of time. For production applications this is cost and time prohibitive. Therefore, the next best thing is exposing your engine to multiple heating and cooling cycles under various load and RPM's, which is described in the following paragraph. The heating and cooling break in process continues over a period of time and does not need to be run on petroleum oil.

Breaking in a new engine is the one area that petroleum oil is better for than synthetics. You see, petroleum oil has a very low film strength which is ideal for breaking in a new engine. That is why we recommend you run the factory installed petroleum oil for about the about the first 500 miles or up to the first scheduled oil change. Then drain the oil, remove the factory installed oil filter and then install AMSOIL Synthetic motor oil and an AMSOIL Super Duty oil filter and your ready to go.

Further heat cycling break-in will continue during the multiple heating and cooling cycles from driving your vehicle under varying RPM and engine load conditions and then shutting it down for a long period of time to let it cool completely. The multiple heating and cooling cycles are a extremely important factor in properly breaking in a new engine and are often an overlooked factor in the total break-in process. These heating and cooling cycles achieve what is called stress relieving. Back in the "old days" of engine manufacturing, after casting and before an engine block was machined, it would be set outside for several months to age, during which stress relieving occurred naturally, then the block was machined, which helped to produce a better engine than one that was machined immediately after casting.

By changing the factory installed oil and filter after the first 500 miles you will also be removing the initial wear-in particulates present in the oil and filter. The reason for this is that during initial wear-in there is very high particulate contamination in the oil. These particulates consist mainly of microscopic particles of aluminum, bronze, copper, lead and iron, plus soot particles and other by-products of combustion in your oil. Your filter cannot filter out all these small particulates as many are sub-micron size and too small for the filter to trap, BUT they are also small enough to fit between your bearing and other internal clearances and cause wear. That is why we recommend to that in order to properly break-in a new engine, regardless of what your new car salesman or dealership personnel tell you, is to perform the first oil and filter change at 500 miles or up to the first scheduled oil change. Then you can convert to AMSOIL Synthetic. On a diesel engine we recommend running petroleum oil then to 5000 miles before converting to AMSOIL Synthetic Oil.

However, please note that if a customer chooses to use AMSOIL synthetic motor oil in a brand new engine without waiting until 500 miles or the first scheduled oil change this is perfectly ok. In fact, vehicles such as Dodge Viper and Chevrolet Corvette come factory filled with synthetic oil. However, since most new vehicles come filled with petroleum oil, it only makes good sense to change to AMSOIL at the first scheduled oil change interval, or 500 miles if the customer does not want to wait until the first scheduled oil change. New engine components generate high levels of wear metals and can contain contaminants from assembly. By allowing the engine to operate with the petroleum oil until the first oil/filter change interval, the wear metals and contaminants are removed prior to installing AMSOIL.

There are a couple primary reasons for this recommendation.

1. New engines or engine components generate high wear metals to begin with and generally contain debris from machining and assembly. It is more beneficial to allow these wear metals to collect in an inexpensive motor oil than to circulate throughout the crankcase for extended periods in a synthetic motor oil. By operating the vehicle to its first drain interval with a petroleum oil, these wear metals and manufacturing debris collect in the oil and are then flushed out of the crankcase when drained. This allows for a much cleaner operating environment for the synthetic lubricant.

2. Within the first miles of operation, if there are any defects in the assembly or workmanship of the engine components, then they may be corrected before installing the more expensive synthetic motor oil. Occasionally, rebuilt engines may have re-machined components or materials which can sometimes be mismatched. These problems will develop in a fairly short period of time. If excessive oil consumption or any other problem is noted, this should be corrected prior to changing to AMSOIL Synthetic Oil.

For racing applications, a synthetic motor oil can be installed right away. These engines are frequently disassembled and rebuilt under more exacting conditions and require the improved wear protection of a synthetic motor oil. Extended drains are rare due to contaminants such as fuel dilution and dirt entry are common, therefore we would recommend oil analysis to determine serviceability of the lubricant.

AMSOIL Engine Flush: In a new engine with less than approximately 15,000 miles it is not imperative that AMSOIL Engine Flush be used. In an engine with more than 15,000 miles and beyond, that has been using petroleum oil the entire time, we highly recommend using the AMSOIL Engine Flush. What the engine flush will do is remove the petroleum oil sludge & varnish deposits from your engine and properly prepare your engine for AMSOIL Synthetic Motor Oil. You simply pour in one can for every 5-6 quarts of sump capacity (one can is sufficient for most all passenger cars & light trucks, with the exception of diesels), and let the engine idle for about 15 minutes then drain the oil and remove the filter while the oil is still warm. Do not drive the vehicle with the engine flush installed. If you have an extremely dirty or high mileage engine then we recommend installing a new engine oil filter prior to adding the flush so that you have full capacity of the filter available for capturing and holding the dirt particles that the flush removes. AMSOIL's engine Flush is a detergent based flush with some kerosene and other petroleum distillates that act as the carrier for the flushing and cleaning agents. The detergent used is a 2-butoxyethanol, glycol ether and is essentially a very concentrated form of the detergents used in motor oil.

AMSOIL Synthetics are naturally cleansing and also high in detergents. What happens when you operate an engine on petroleum oil, the sludge and varnish deposits that occur as a result of using petroleum oil will accumulate around your pistons, rings, seals, valvetrain, etc.. and actually help to seal your engine. This type of petroleum oil deposit "sealing" can lead to problems such as piston ring sticking, sludge deposits in valve covers and oil pans which can lead to decreased oil pump capacity output and restriction of critical oil galley passageways over an extended period of time, plus many more issues which we will not go into detail in this discussion.. These deposits are highly detrimental to the proper function and longevity of your engine.

What occurs when you use the AMSOIL Engine Flush is that it cleans all these deposits out from your engine, both the highly accumulated deposits as well as the sub-micron deposits which have accumulated in the microscopic valleys of the aluminum, copper, iron, etc.. engine components. If you do not use the engine flush the AMSOIL Synthetic Motor Oil will do essentially the same thing the flush does but take a much longer period of time. During this time, which is greatly accelerated when using the AMSOIL engine Flush, the engine is going through a phase where these deposits are being removed, or have been removed. What exists now is that these microscopic valleys in the iron, aluminum, copper, etc.., are now empty. It takes some time for the molecular structure of the AMSOIL Synthetic Motor Oil to fill these microscopic valleys. This can be as short as a few hundred miles or as long as a few thousand miles, depending on the internal condition of your engine. During this phase you may, or may not, notice slightly increased oil consumption BUT only until the uniform molecular structure of the AMSOIL Synthetic Motor Oil can re-seal these microscopic valleys. Most people do not even notice this phase, but we like to make people aware of it so they understand this process. This is perfectly normal and the oil is doing exactly what it was engineered to do.

You may have heard the myth that synthetic oil can cause engine seals to leak. Synthetics absolutely do not cause seals to leak, they simply may only reveal an existing leak path and seal which has failed and is in need of mechanical replacement. Either the seal lip is worn down or the seal is hardened and cracked from old age, heat and ozone. What happens is exactly as we described above. If you have a very old engine that has been running petroleum oil, and it also leaks, for example around the rear-main oil seal, then chances are it will leak more with synthetic oil. This is commonly referred to a false seal. AMSOIL Synthetic Motor Oils are recommended for use in mechanically sound engines! If you have a vehicle that leaks oil excessively, then repair the seal prior to converting to AMSOIL.

AMSOIL Benefits:

Once you have installed AMSOIL you will notice the following benefits:
easier cold weather starting, cold weather pumpability and circulation, smoother engine performance and more horsepower, reduced exhaust emissions, superior wear protection, improved fuel economy, extended engine life, extended starter life, excellent engine cleanliness, long drain intervals, longer spark plug life, reduced engine temperatures, reduced oil consumption, excellent resistance to sludge, coke, varnish deposits (Thermal Stability), reduced/eliminated piston groove sticking, reduced/eliminated valve sticking, superior shear stability, superior resistance to viscosity increase (Volatility Resistance), superior film strength, money and time savings. You will not get any of these benefits with conventional petroleum oil.

When you compare....there is simply no comparison. AMSOIL is the best motor oil!

Customer Sold on AMSOIL Quality and Value.

That's what today's savvy consumers want.

According to marketing analysts, the average consumer no longer accepts general sales pitches full of empty promises. The Internet gives consumers instant access to nearly every possible product or service. They look for quality information, conduct price comparisons and then make buying decisions.

The bottom line: more bang for their buck. And when that consumer is raising seven children, top quality products and savings are an even greater priority.

Scott Boring, Oakfield, N.Y., has seven children with his wife Teri. He's looking for quality and savings to keep his 1997 GMC Yukon, with a 5.7 litre V-8 engine that "isn't noted for gas mileage," running down the road carrying his large family as efficiently as possible.

A friend told Boring about AMSOIL products. He promised better gas mileage - an important selling point with today's high gasoline prices - more efficient performance and longer life.

The vehicle had 40,000 miles on it when Boring installed AMSOIL products bumper to bumper.

"I did it all at one time, just to see the difference," Boring said. He installed AMSOIL Severe Gear 75W-140 Synthetic Gear Oil, used AMSOIL Engine Flush and then installed AMSOIL 10W-40 Synthetic High Performance Motor Oil and AMSOIL Universal Automatic Transmission Fluid.

"I especially like the ATF," Boring said. "The truck shifts smoother and the transmission is quiet. All you hear is the tires on the ground. I've tried other synthetics, lots of them. I just never saw any difference. But, with AMSOIL, I saw a difference right away."

The first tankful of gasoline increased his mileage from 15 mpg to 20.5 mpg. "I swear I didn't believe it," he said. "I'm averaging between 19 and 21 mpg all the time.

"This stuff is awesome and I'm letting all my friends know about it."

AMSOIL Customers Appreciate Greater MPG

Although results vary because of a variety of factors, a common denominator among AMSOIL motor oil users is an improvement in fuel economy.

Independent testing reveals that AMSOIL Signature Series 0W-30 motor oil passes the API Energy Conservation Sequence VI test with a rating 38 percent higher than the API minimum specifications.

"The test results show that AMSOIL has the potential to save energy by conserving fuel," said Technical Services Manager Ed Kellerman. "In most cases it can increase mileage, but at the very least you're getting superior engine protection."

Ralph Sites, a police officer in Rustburg, VA, said he put AMSOIL 10W-40 Synthetic Motorcycle Oil in his 2002 GL 1800 Honda Gold Wing when it had 4,550 miles on the engine. "I had been getting 30 miles per gallon," Sites said. "I was supposed to be getting 40 to 45 miles per gallon."

His first oil change to AMSOIL improved his mileage to 38 miles per gallon. At 6,500 miles on the engine, after replacing the final drive oil with AMSOIL Severe Gear 75W-90 Gear Lube, he improved to 40 miles per gallon.

"I switched to AMSOIL for the long-term gain. The improved gas mileage was just a bonus. AMSOIL is less expensive than Honda's synthetic and I don't have to change it as often. It's a win-win situation."

He bought the bike new in January 2002 and had put 12,000 miles on it in August. He said the improved mileage he's gotten since switching to AMSOIL has saved him $102 just in gasoline.

Jeff Bailey in Fulton, Mo., said his 1996 Lexus GS300 with 81,000 miles on it also gained fuel efficiency when he switched to AMSOIL motor oil.

"The car wants premium gasoline," he said. "I drive about 18,000 miles a year. I ordered your synthetic product and absolutely astounded.

"I was used to getting about 20 mpg overall and having a little low-rev torque."

Since switching to AMSOIL motor oil, Bailey gets 24 mpg and uses regular gasoline.

"The engine feels even more flexible," he said. "I've used AMSOIL now for my wife's anemic Camry 2.2 litre and have calculated that I have saved about $120," he said. "Thanks AMSOIL for an awesome product. You have a customer for life."

Likewise, Lance Okeson of St. Paul, Minn., gained miles per gallon after switching to AMSOIL motor oil in his 1995 Cutlass Supreme.

Okeson made the switch after learning about AMSOIL from a customer of his at a quick lube where he works. His customer was so enthusiastic about AMSOIL, Okeson did some research on the AMSOIL Website and decided to try the products. A trip from the Twin Cities to Fargo, N.D., in a steady 17 mile-per-hour wind, and back showed him an increase from 24 mpg to 30.5 mpg.

"I have never gotten 30 plus mpg with that car," Okeson said. "I have two other vehicles that I switched over to AMSOIL motor oil. One is a 4x4 and the other is an old muscle car. I switched the transmissions and the differentials in those vehicles as well."

ASE Master Technician Sold on AMSOIL

Mark Deschner, Friendswood, Texas, is an ASE Master Technician and Manager of the West Pear Land Tire & Auto Store.

He recently was able to demonstrate the superior quality of AMSOIL Synthetic Lubricants when he had to change out a leaking intake manifold on his 1991 Chevrolet 1/2 ton pickup truck, with more than 183,000 miles on the original engine.

"When my lead technician took the intake manifold off, for the first time ever, he couldn't believe how clean the lifter valley and the top of the cylinder heads were on my truck," Deschner said.

The technician thought Deschner may have changed it before. But Deschner assured him he had never had the intake off before.

"He always made fun of me for only changing the oil once a year and the filter twice a year," Deschner said. "I think that seeing how clean the intake and cylinder heads are in my truck has changed his mind about AMSOIL products. I've always believed in them and my truck runs AMSOIL for all lubricant needs."

He uses AMSOIL 10W-40 Synthetic Motor Oil, EAO24 Absolute Efficiency Oil Filter, TS31 2-Stage Air Filter, GF111 Fuel Filter, 80W-90 Synthetic Gear Lube, Universal Automatic Transmission Fluid, Synthetic Multi-purpose Grease, P.I. Performance Gas Additive, Rain Clear Windshield Protectant and Bosch windshield wiper blades.

"As you can see, I have pretty much converted the entire truck over to AMSOIL products," Deschner said.

Preferred Customer Sold on AMSOIL Quality

Peter Virgona of Merrick, N.Y. is a self-proclaimed oil enthusiast. �I do a great deal of reading and research, always looking for the best oil,� Virgona said. �The more I read the more I realized AMSOIL was the best �true� synthetic I could buy. After using Mobil 1 since 1986, I made the switch to AMSOIL.�

Virgona is a warehouse worker, but he has many years of experience working on cars.

He drives a 1999 Ford Crown Victoria that has nearly 98,000 miles on the engine. He switched from Mobil 1 to AMSOIL 5W-30 Synthetic Motor Oil (ASL).

�The difference was immediate and significant,� Virgona said. �The idle became much smoother. There are times I can�t tell if the car is running. It also became much more responsive to the gas pedal, so much more responsive my wife asked me what I did to the car.�

Virgona has owned the car for almost nine years. �Not surprisingly, the gas mileage improved significantly,� he said. �This car always averaged 15 miles per gallon going back and forth from work. It now averages 16.5 mpg. That�s a 10 percent increase. I truly didn�t expect such a big change.�

He waited to report his findings until after he had driven the car at least 5,000 miles �to confirm that the numbers are average and not just a fluke.�

Virgona also has installed Ea Air and Oil Filters in his vehicles.

He told his sister-in-law about AMSOIL and then changed her oil over to AMSOIL 5W-30. She drives a 1996 Dodge Caravan with a 3.0 litre V6 engine. According to Virgona, she had always used conventional motor oil with regular oil changes every 3,000 miles.

�Nonetheless, she had a significant amount of sludge that was obvious under the oil fill cap,� he said. �She also experienced a very loud lifter noise that would come and go. Presumably, the sludge was affecting the oil circulation to the lifters.�

Oil consumption in the van was also increasing, using about one quart every 1,500 to 2,000 miles.

�I switched the van to AMSOIL and put in a new filter,� Virgona said. �Within 1,000 miles the lifter noise was all but gone. By 3,000 miles, virtually all the sludge was gone. I drained and refilled the oil a second time with AMSOIL 5W-30. The oil consumption is now down to one quart every 3,000 miles, with no more lifter noise.

�I am very happy with AMSOIL and plan to use it from now on. I recommend it to anyone who wants a great synthetic oil.�

Virgona buys his products through the AMSOIL website. �I always get my product within 48 hours,� he said. In fact, he just had a case shipped to his father in-law in Florida because he believes in AMSOIL products and wants others to experience their benefits. In fact, he�s considering becoming a Dealer.

Virgona respects that he can get detailed technical information about AMSOIL just by checking the website. �AMSOIL puts out performance test results for everyone to see. I definitely appreciate that.

�People are usually very, very loyal to AMSOIL. They know it�s the best.�

AMSOIL Gives Life to a Sweet Old Cadillac. Making a skeptic into a believer again.

Dear AMSOIL,

I thought you might appreciate hearing my AMSOIL story. When the opportunity arose last year to purchase my mother-in-law's 1987 Cadillac DeVille, I jumped at the chance. A true low mileage survivor, it was in near pristine condition. I was proudly showing it off to a mechanic friend when he said, "Uh-oh, you bought an HT-4100? Good luck buddy."

After much research I understood what he meant. The HT-4100 was rumored to be one of the most troublesome engines Cadillac ever built. The problems are numerous: an aluminum block with cast iron heads that expand and contract at different rates causing premature head and intake gasket failure, coolant loss into the oil, and finally main and rod bearing failure. They also have a heavily loaded distributor gear, weak timing gears, and sludging issues.

My first thought was, if ever an engine needed AMSOIL, it's this one. I first heard about AMSOIL at the old Brohman Dragway in the late 1970s from a fellow racer who swore by it. For the past 10 years, I've used various synthetic oils with favorable results, but never AMSOIL. Then I talked with Dave Mann, the AMSOIL Dealer in my home town, and told him my story. Having spent 19 years as a lubrication specialist with Ford, Dave knows his stuff. He made several recommendations, and shared with me his excellent e-book on motor oils.

I also asked around at the Cadillac owners group I belong to, and almost every one of them said, "Don't buy AMSOIL! It's too expensive and won't do you any good. You need this or that oil with this or that additive," and so on. So who was I to believe?

Having spent over 25 years in advertising and marketing, I have a strong skepticism for extravagant claims made by manufacturers. Usually, when you hear impressive adjectives like "advanced" and "superior," someone just wants your money or your vote (or both). So I read the science; from AMSOIL and from several independent studies. I came to the conclusion that it really is an excellent product. It also intrigued me that one of the primary sales points made by AMSOIL is to convince you to buy LESS of their product. That kind of marketing is contrary to anything I've experienced, and elevates AMSOIL's credibility level exponentially.

I switched the Cadillac over to AMSOIL 5W-30 (ASL) last fall, then put in AMSOIL 10W-30 (ATM) this spring (even though it's not a turbo, I like the extra wear protection offered by this formula). Rather than letting the oil go a full year, I change it every six months, during which time it accumulates about 6,000 miles. My dad was an auto mechanic and taught the 3,000-mile oil change rule like it was the 11th commandment - that kind of conditioning is hard to overcome. With this frequency, I still spend less money than if I changed the oil on a three-month/3,000-mile schedule. I use the money I save to have drain samples tested by an independent lab each time.

The Deville now has 50,000 miles and runs like a fine Swiss watch. I have not had a single problem with the 'troublesome' HT-4100 engine. It runs roughly 10 degrees cooler than with regular oil, and my gas mileage has increased by 10%. It has become my mission to get 200,000 miles from this car. With AMSOIL, I might just make it.

As an addendum, I also recently switched my wife's 2003 Oldsmobile Silhouette minivan to AMSOIL. Since we've owned it, this car has had a lifter clatter for the first 10 seconds on cold starts. Literally, on the first start after putting in AMSOIL, the clatter was gone.

Thanks AMSOIL. By making a superb product that truly does what you say it will do, you've given new life to a sweet old Cadillac, and made a believer out of this devout skeptic. (see photos of car and engine)

HDT Sets AMA Land Speed Record with AMSOIL

Hayes Diversified Technologies (HDT), located in Hesperia, California, produces diesel powered tactical military motorcycles for the U.S. armed services as well as the UK and EU NATO countries. Founded in 1961, the company originally manufactured electro-mechanical switches and relays to the military & aerospace industries.

The new HDT motorcycles are diesel machines combining both power and environmentally friendly performance efficiency. We are talking about a bike that gets 100 miles to the gallon AND can do 100 mph.

The HDT team was out on the Bonneville Salt Flats earlier this month, striving to establish new national and world records. Displaying the AMSOIL colors while going through the paces at Bonneville, they offered up quite a number of very strong endorsements with virtually no prompting. We noticed an increase in horsepower right away when compared to Delvac 1,� said Fred Hayes, founder/CEO of HDT. What was quite surprising was the condition of the engine after a 50-mile run-in and over 120 full-throttle dyno runs. The camshaft bearings, the small and large end rod bearings, didn't even look like they had been run. During that series of dyno runs, we registered the highest horse-power and torque readings ever.�

Dave Anderson, AMSOIL Technical Product Manager, had flown to Bonneville to witness and participate in the pursuit of new land speed records. Hayes said to Anderson, "Our testing proved that AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil provided better cam bearing lubrication, better transmission operation and less blow-by than our previous oil. We picked up just over one horse power at the rear well." This is a 3.7% increase and worth a 1 tooth higher gear ratio. In addition, it appears that overall coolant temperature was down about five degrees. That is roughly a 2.5% decrease in operating temperatures.

Very few bikers would be opposed to increased horsepower with lower operating temps, simply by switching over the lubricants.

With over a year of testing, we have found that AMSOIL products continually outperform all other lubricants. AMSOIL provides improved performance, increased fuel economy, lower oil consumption, and significantly reduced engine wear in all operating conditions.

AMSOIL Boosts Bottom Line for Grain Hauler

Burnell Keller of Castroville, Texas hauls a lot of corn. Saving downtime and maintenance costs boost his bottom line.

Since the 1960s, Keller Grain, Inc., at Castroville has bought high quality white and yellow corn from local farmers and trucked it to processing plants across the state of Texas. "These trucks put on about 12,000 miles a month," said Keller, the company's owner.

He was running Exxon XD3-30 motor oil in his Freightliner and changing it every 10,000 miles. He heard AMSOIL products could cut his operating and maintenance costs in half, provide better fuel economy, easier starts and extended oil drains at least three times longer than he was getting.

"We were fixing to extend the drain to 15,000 miles," Keller said. "But a sample of the Exxon motor oil analyzed at 10,000 miles came back saying the oil needed to be changed. I said, let's give AMSOIL a whirl."

After an engine flush, Keller installed AMSOIL 15W-40 Heavy Duty Diesel and Marine Oil in his Freightliner, with more than 400,000 miles on the engine.

"We did this procedure three times at a 15,000-mile analysis and filter change only," Keller said. "Each time the oil sample report came back saying the oil was good for continued use."

After the third round of analysis, the oil was changed. Keller plans to continue with 15,000-mile analysis and filter changes and to continue to use the same oil for an interval of 50,000 miles.

"That's about five times longer than before," Keller said. "It's very good. Keller Grain is now convinced that AMSOIL is a superior product and that anybody can save money using AMSOIL products."

New Life for Dodge Ram

Preferred Customer Lyle Reinier from Mesa, Ariz. has been using AMSOIL products for four years with complete satisfaction. He said that when he started using them in his 2001 Dodge Ram they �changed the way it ran.�

Now Reinier drives a 2004 Dodge Ram. He uses AMSOIL Synthetic 5W-30 in the engine, AMSOIL Synthetic Universal Automatic Transmission Fluid in the transmission and 80W-140 Long Life Gear Lube.

�AMSOIL has given this truck life that it was hiding before,� said Reinier. Reinier said the Ram now pulls stronger and runs smoother than it did before. He made the switch to AMSOIL when the truck hit the 3,000-mile mark. �What comes as a surprise to me is that my Dodge dealer had no problem doing a complete drain and fill with AMSOIL,� said Reinier.

Reinier said the dealer removed all the Dodge transmission fluid and refilled the truck with AMSOIL ATF. �Within a mile or two I could feel the transmission was smoother and showed a difference in how it performed,� said Reinier.

Reinier also uses AMSOIL in his dirt bikes. He and his wife have been using AMSOIL 0W-40 Formula 4-Stroke since it was introduced. Within the last year, Reinier performed a big bore and a valve job on their bikes in search of more power.

�The insides of the cases, transmission gears and crank shafts were all like brand-new,� said Reinier.

Reinier said the cylinder walls of each bike still showed some cross hatching from the original bore. He also said the bikes run quieter, smoother and cooler than they did before the switch to AMSOIL. Both bikes have their original clutches and have logged over 4,000 trail miles.

Customer Discovers a Burning Desire For AMSOIL

Dealer Mark Licht of Andover, N.J., was on a follow-up visit at Jimmy's Service, Inc., of Hackettstown, N.J., when the integrity of AMSOIL ATF was put to a new, on-the-spot test.

Licht showed shop owner Jimmy Naranjo several pieces of literature on oil and ATF testing results. After listening to Licht talk about the benefits of AMSOIL ATF, Naranjo turned to him and said, "You're full of it."

Licht continued to explain all the features and benefits that AMSOIL ATF has to offer, but Naranjo interrupted and told him, "There is only one way to prove this ATF is any good."

Naranjo went to his shelf and opened two brands of transmission fluid he uses and poured some of each onto his metal workbench. The shop owner than poured some AMSOIL ATF next to the other two brands. "I had no idea what this guy was about to do," said Licht.

Naranjo then took out his torch and put the flame directly on the first brand of transmission fluid he commonly used. After about 30 seconds the little puddle of transmission fluid started smoking. Naranjo proceeded to the second brand he stocked in his service shop and repeated the process. After another 30 seconds, that brand of transmission fluid began smoking badly.

"Now it's AMSOIL's turn and I must admit I thought my fluid was going to smoke out just like the others with that direct flame," said Licht.

Naranjo held the flame on the AMSOIL ATF for over two and a half minutes and there was absolutely no smoke.

"He quickly turned to me and said he'd take a 30-gallon and a 55-gallon drum of the ATF," said Licht. "We couldn't believe our eyes!"

Now Jimmy's Service stocks the entire XL line of oils, all of the AMSOIL 25,000-mile oils, AMSOIL diesel oils and all of the AMSOIL diesel additives. The shop also carries AMSOIL filters, 2-cycle oils, Power Foam Engine Cleaner and Home Heating Fuel Extender.

CROSS COUNTRY TRIP PROVES AMSOIL PERFORMS

Owners of motorhomes, who often travel long distances, are particularly concerned with finding ways to save on fuel costs.

A Texas man discovered AMSOIL motor oils and lubricants lived up to all of his expectations in a journey from Texas to Alaska and back in 2004.

"I have a 1998 Dutch Star by Newmar 38-foot motorhome with a 300 horse power Cat engine," said Shelby Rash, Richardson, Texas. "I also tow a car behind." Throughout 2003, Rash averaged 7.1 miles per gallon. "I use AMSOIL products and believe in them," Rash said.

He took AMSOIL 15W-40 Heavy Duty Diesel and Marine Oil, an AMSOIL oil filter, Torque-Drive Synthetic Automatic Transmission Fluid, AMSOIL 75W-90 Synthetic Gear Lube, AMSOIL Universal Automatic Transmission Fluid, for power steering/hydraulics, and the AMSOIL Synthetic Multi-Purpose Grease to a shop in Dallas in January 2004.

"They installed AMSOIL in everything, including the grease fittings," Rash said. "I installed a new AMSOIL air filter and oiled the front wet axles myself. I filled up with diesel and added AMSOIL Cetane Boost and Diesel Fuel Additive to the tank, as well." Then Rash took his four-month, 11,000-mile trip.

"I used the two additives each time I filled," he said. "I also attended two RV rallies where I 'dry-camped with a generator' for a total of 10 days during this time." The only thing he did was change the oil filter during that time.

"I averaged 8.6 mpg since January 2004 for these 11,000 miles," Rash said. "This sure helped with the high fuel prices. Just by changing to AMSOIL I averaged 1.5 mpg better.

"Is AMSOIL worth a try? I think so."
