Why Use A Dedicated Small Engine Oil?

How is small engine oil different than motor oil for cars? Today’s cars and trucks have emissions sensors and catalytic converters. Therefore, modern automotive engine oils are required to have ingredients that are compatible with these components.

Small engines do not have these emissions devices. Therefore, a specialized small engine oil has far less design constraints. This Small Engine 15W-50 is loaded with anti-wear and detergent ingredients. The result is long service life and the ultimate anti-wear protection.

Suitable Applications For AMSOIL Synthetic 15W-50 Small Engine Oil

For small gasoline, diesel, liquid propane or natural gas engines in the following applications.

  • Mowers (Zero-Turn, Riding, Stand-on)

Features And Benefits Of AMSOIL Synthetic 15W-50 Small Engine Oil

  • Suitable for most any type of four-cycle small engine
  • Safe for engines powered by gasoline, liquid-propane, natural gas or diesel
  • Provides powerful wear protection
  • Capable for long oil change intervals
  • Combats oil consumption
  • Flows well in cold climates
  • Wet-clutch compatible
  • Delivers anti-corrosion protection for off-season storage and wet climates

Capable Of Long Service Life

Commercial small engines work hard and sometimes oil change intervals are pushed to the limit. AMSOIL over-built the Small Engine Oil series for ultra-long service life. The result is consistent viscosity, minimal oil consumption and clean engine internals.

Fights Oil Consumption

AMSOIL Synthetic 15W-50 Small Engine Oil resists viscosity breakdown and oil usage during heavy-going. Testing shows that AMSOIL Synthetic Small Engine Oils reduce oil consumption by up to 61% over leading small engine motor oils.

Quick Oil Flow For Cold-Starts

AMSOIL Synthetic 15W-50 Small Engine Oil has a cold-pour-point of -36°C (-33°F). This oil offers immediate oil flow in both splash- and pressure-lubed engines.

Rust Protection For Engine Internals

Many small engines are stored for the off-season. Some are operated in wet conditions. AMSOIL considered these factors and added robust anti-corrosion ingredients to this product. AMSOIL Small Engine 15W-50 protects your investment in storage and in service.

Suitable For Wet-Clutch Transmissions

AMSOIL 15W-50 Small Engine Oil does not contain friction modifiers. This makes this product suitable for wet-clutches found in motorcycles, ATVs, UTVs and Side-by-Sides.

Mixing AMSOIL Synthetic 15W-50 Small Engine Oil With Other Brands

AMSOIL Synthetic 15W-50 Small Engine Oil is compatible with all other brands of conventional, semi-synthetic and synthetic engine oils. While you can safely mix this product 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 Of AMSOIL Synthetic 15W-50 Small Engine Oil

AMSOIL Synthetic 15W-50 Small Engine Oil can stay in service up to 200 hours or one year (whichever comes first).
