AMSOIL 10W-40 100% Synthetic Small Engine Oil
AMSOIL 10W-40 Synthetic Small-Engine Oil is designed to deliver superior performance and protection for small engines found in tools like mowers, generators, and power washers. It surpasses conventional oils in terms of wear protection, thermal stability, and carbon deposit control. This oil helps maintain engine power and promotes long engine life, ensuring equipment dependability. Its tough formulation combats engine stress caused by frequent start-ups, variable engine speeds, and heavy loads. The oil is multifunctional and can be used in gasoline engines, off-road diesel engines, and certain transmissions without friction modifiers, meeting JASO wet-clutch standards. It's known for reducing volatility and soot production, enhancing fuel economy and extending engine life. The oil also offers superb cold-start protection with a cold-pour-point of -48°C (-54°F), providing immediate oil flow during cold starts, crucial in reducing wear.

AMSOIL 10W-40 Small-Engine Oil
COMMERCIAL-GRADE
Engine dependability is vital to running a profitable business, yet most small-engine oils we’ve tested are nothing more than re-labeled automotive oils, which are formulated with fuel economy in mind, not durability. That won’t cut it. Compared to liquid-cooled automotive engines, small engines run hotter; operate under constant load; generate more oil-damaging contaminants; suffer from neglected maintenance; and are exposed to dirt, rain, snow and other extremes. Simply put, they’re far tougher on oil that most people think.
AMSOIL Small Engine Oil isn’t merely a re-badged automotive oil. Instead, we designed it from the ground up specifically for small-engine dependability. You can rest assured your engines are protected even during periods of extended use when there’s no time for scheduled maintenance. It’s built to solve the problems that plague small engines, including wear, power loss, oil consumption, harmful carbon deposits and stuck rings and valves. It helps landscapers, contractors and other professionals get more work done and save money.
- Protects up to 200 hours
- Helps extend engine life
- Rust-inhibited
Excellent Wear Protection
AMSOIL Synthetic Small-Engine Oil is a shear-stable, high-film-strength formulation fortified with a heavy dose of anti-wear additives. It does not thin out due to mechanical shear, ensuring a thick lubricating film. It forms a durable barrier that protects against metal-to-metal contact.
Reduces Oil Consumption
In lab testing, AMSOIL 10W-30 Synthetic Small-Engine Oil reduced oil consumption 61 percent compared to three leading 10W-30/SAE 30 motor oils (based on 125-hour lab tests of small engines using AMSOIL 10W-30 Synthetic Small-Engine Oil and three leading 10W-30/SAE 30 motor oils). Its heat-resistant synthetic base oils provide low volatility, excellent viscosity stability and strong oxidation resistance. Engines run longer between top-offs, providing peace of mind they won’t fail due to oil starvation and will run dependably in the harshest conditions.
Formulated for Power
Engine wear, carbon deposits, valve sticking and piston-ring sticking reduce engine power. AMSOIL Synthetic Small-Engine Oil prevents ring and valve sticking while helping eliminate carbon deposits from forming. As a result, engines produce maximum power throughout their service lives, helping you get more work done.
Extreme-Temperature Performance
AMSOIL Synthetic Small-Engine Oil’s saturated molecular structure offers outstanding extreme-heat resistance. In addition, we’ve fortified the oil with potent antioxidant additives that provide further resistance to damaging heat. Its powerful detergent additives fight carbon, varnish and sludge to maximize engine life. In extreme cold, the oil’s naturally high viscosity index and lack of paraffins (waxes) ensure it remains fluid and flows quickly, providing easier cold-weather starts and fast startup lubrication for reduced wear.

Exactly what I needed!
Bought this for use in newer Yamaha Drive2 QuieTech golf carts. This oil is designed for such engines - air-cooled, splash lubrication, and especially that they're driven hard (golf cart community with many carts set up for higher-than-stock max speeds). The earlier Drive generation carts had 10w-30 as the oil spec - the spec for the newer QuieTech carts went to 10w-40. I've heard or read nothing definitive about why Yamaha changed the spec. My "guesestimation" is that it's likely due to the QuieTech carts running a LOT hotter, likely due to all of the changes made to isolate and reduce the engine noise. Not much freely flowing fresh air comes through the engine compartment on these! I have had zero oil-related issues with the 10w-30 in the earlier carts - should experience the same with the newer carts using this oil!
Small Engine Oil
I started using this in all my small engines around the shop, and it does a good job of helping engine performance, it keeps the engines internals clean, and it gives me piece of mind that these smaller engines are protected. My old riding mower couldn't go 20 hrs before the oil was already starting to darken. It had 10 hrs on it when I sold it and looked new.
The only oil to use
Amsoil is the only oil product I use any of my oil needs. Superior quality.
