Hi, I’m Dave - a former Ford Truck/Automotive Engineer with 40 years of combined professional experience working with lubrication systems and using and promoting AMSOIL products. My trucks, heavy equipment, farm and powersports vehicles experience extreme use, and I use AMSOIL products in every single one. Enjoy the site!

Racers at all levels have recognized the benefits of using synthetic lubricants in their race vehicles. This isn't surprising to those of us who understand the technical advantages synthetics provide, especially in high-stress applications like motorsports where every horsepower counts.

Synthetic Oils: The Racer's Edge

According to Performance Racing Industry, synthetic motor oils have become quite popular in the world of racing. Despite costing more than conventional oils, racers of all levels have embraced synthetics for their ability to improve performance and extend equipment life.

"Obviously, if you reduce friction in the engine, you get more horsepower to the drivetrain, which is what every racer is looking for," says Terry Thompson of Performance Products in Oakland, Calif. "What you'd have to spend on modifications to get five or 10 more horsepower out of a racing engine, versus just changing oils, makes this a much less expensive option. Basically, it's cheap horsepower. Virtually every serious racer is going to the synthetics. There is just no comparison."

The Business Case for Synthetic Racing Oils

Carrying synthetic motor oils presents businesses with two clear benefits: higher profit margins and satisfied customers. By suggesting these products, they do both parties a service, says Michael Wachholz of Prospeed Motorsport in Scottsdale, Ariz. "The dealer makes more money, and by putting a better product in the vehicle, the customer ends up being a happier camper."

This profit potential makes AMSOIL an attractive option for those in the automotive service industry. If you operate a repair shop or service center, becoming an AMSOIL Installer Account can give you access to premium products at wholesale prices, helping increase your profit margins while providing superior service to your customers.

As the significant benefits offered by synthetic oils have become clear to racers, cost has become less of a factor. "Once they get into the synthetics, they just expect that they're going to pay more and there's not that wincing when you tell them the cost," says Bill Love of OG Racing in Sterling, Va.

Selling Synthetic Oils: Education is Key

Hard data, testimonials and a knowledgeable sales staff are all important tools in selling synthetic racing oils. Product data bulletins and fliers provide important information that can aid in a sale. "We like to have a lot of printed information available to go along with the product, so the customer can pick that up, read about the product and see what it really does," says Chris Paulsen of C&R Racing in Indianapolis, Ind. "We're very driven on good data to back up what the product is supposed to do."

If business owners and salespeople use the product they're trying to sell, it can be a significant advantage when speaking with a potential customer. "We can tell them, 'Look, this is a product that we use all the time and that we feel very strongly about,'" says Love. "That's what they want to hear, not, 'They say good things about it,' or 'I've heard good things about it.' It's, 'We use it. We like it. We respect it.'"

For racing shops and parts stores, becoming an AMSOIL Retail Account allows you to offer these premium products directly to your racing customers, enhancing your reputation as a provider of top-quality performance products.

From the Track to the Street: Expanding the Synthetic Market

Because they've already witnessed the benefits of running a synthetic oil in their racing vehicles, racing customers are likely to be also interested in synthetic lubricants for their personal vehicles, tow vehicles, recreational vehicles, etc.

"Synthetics have become very much accepted today, and once a person gets switched over, they start to see the benefits and then they want to try it for their transmission, rear end, etc.," explains Butch Stevens of BSR Products in Concord, N.C.

"In the store, I have information available so people can read up on the products," says Stevens. "We have a little mockup display out front with a little bit of everything, along with literature for the different types of oils. And I have the product available at the track—that's where our claim to fame comes in."

This widespread acceptance of synthetic lubricants has created opportunities for entrepreneurs. If you're passionate about performance and quality, becoming an AMSOIL Dealer can allow you to build a business around products you believe in while serving the racing and performance automotive communities.

The Technical Advantages for Racing Applications

What makes synthetic oils so beneficial for racing applications? Several key factors contribute to their superior performance over conventional oils:

1. Superior Film Strength

Racing engines operate under extreme pressures and temperatures that can cause conventional oils to break down. Synthetic oils maintain their protective film strength even under these extreme conditions, preventing metal-to-metal contact that causes wear and robs power.

2. Reduced Internal Friction

The uniform molecular structure of synthetic oils reduces internal friction significantly. Less friction means more horsepower reaches the wheels instead of being lost as heat. This translates directly to improved acceleration and top speed.

3. Better Heat Resistance

Synthetic oils can withstand higher operating temperatures without breaking down. This is critical in racing applications where oil temperatures can exceed 300°F during competition.

4. Improved Shear Stability

Under the high-stress conditions of racing, conventional oils can lose viscosity as their molecular chains break down (known as "shear"). Synthetics maintain their viscosity much better, ensuring consistent protection throughout a race.

5. Enhanced Protection During Cold Starts

Even in racing applications, engines start cold. Synthetic oils flow more readily at startup, reducing wear during the critical warm-up period before qualifying or a race.
