Why Should Small Engine Oil Be Different Than Automotive Motor Oil?
Modern automotive motor oils have to be compatible with the sensitive emissions equipment found on today’s cars and trucks. As small engines do not have these emissions components, small engine motor oils have no such design constraints. Therefore AMSOIL can load this Synthetic 10W-40 Small Engine Oil with anti-wear and detergent ingredients that go far beyond those allowed in the latest car motor oils.

Designed For Long Service Intervals
Small engines used in commercial ventures see long hours and there may not be a lot of time for maintenance. AMSOIL considered this factor when designing this product. AMSOIL Synthetic 10W-40 Small Engine Oil protects engines that may not receive oil changes quite as often as they should. It offers plenty of reserve capacity in terms of wear control, detergency and shear stability.
Resists Thinning Out
AMSOIL Synthetic 10W-40 Small Engine Oil is designed maintain its viscosity when exposed to extreme loads and hot operating conditions. It is highly resistant to thinning out or boiling off when pushed to the limit over many hours.
Less Oil Usage
AMSOIL Synthetic 10W-40 Small Engine Oil is less volatile and more shear resistant than regular engine oil. These factors reduce oil consumption to a minimum in mechanically sound engines. Testing proves that AMSOIL 10W-40 Small Engine Oil lowers oil consumption for up to 61% over leading small engine motor oils.
Fast Protection in Cold Weather
AMSOIL Synthetic 10W-40 Small Engine Oil has a cold-pour-point of -39°C (-38°F). This allows for fast oil flow to vital components in both splash- and pressure-lubed motors.
Rust Protection For Extended Storage
As small engines are often stored for long stretches, AMSOIL added powerful anti-rust/corrosion ingredients to this Synthetic 10W-40 Small Engine Oil. Bearings, cylinder bores, pistons, seals and valve-trains stay pristine over long storage periods. This AMSOIL formula protects engines in and out of service.
Suitable For Wet-Clutch and Transmission Use
AMSOIL Synthetic 10W-40 Small Engine Oil does not contain friction modifers. This makes it suitable wet-clutches and transmission use in ATVs, UTVs and Side-by-Sides.
Mixing AMSOIL Synthetic 10W-40 Small Engine Oil With Other Brands
AMSOIL Synthetic 10W-40 Small Engine Oil is compatible with all other brands of conventional, semi-synthetic and synthetic 4-stroke small engine oils. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities of AMSOIL oil.
The use of any aftermarket oil additives is definitely NOT recommended.
Service Life for AMSOIL Synthetic 10W-40 Small Engine Oil
AMSOIL Synthetic 10W-40 Small Engine Oil is capable of oil change intervals beyond the threshold as stated by the equipment owner’s manual. As these intervals can vary widely, use the manufacturers suggested drain interval as a guideline or employ used oil analysis.
