About AMSOIL 10W-30 Synthetic Small-Engine Oil

This new 10W-30 Small Engine Oil will be replacing the AMSOIL Synthetic 10W-30/SAE 30 Small Engine Oil. As the new 10W-30 Small Engine Oil will simply be a repackaged version of 10W-30/SAE 30 Small Engine Oil, there is much we can tell you about it.

  • Suitable for a wide variety of engine types from mowers to pumps to snow blowers
  • Wet clutch compatible making it suitable for transmissions requiring a 30-weight oil
  • Has a strong resistance to thinning out or boiling off
  • Contains powerful anti-rust/corrosion chemistry
  • Formulated for extended oil change intervals
  • Pours down to -40 for year-round service
  • Far more robust formula than automotive engine oils
  • Can be used where 5W-30, SAE 30 or 10W-30 motor oil is suggested
  • Suitable for any gasoline or diesel-powered small engine.

Simply put, if it has a small engine, AMSOIL 10W-30 Synthetic Small-Engine Oil will provide ironclad protection.

About AMSOIL 10W-40 Synthetic Small-Engine Oil

T​he 10W-40 Synthetic Small Engine Oil will share all of the characteristics of the 10W-30 (see above). It will be suitable for any gasoline or diesel-powered utility engine requiring a 10W-40 motor oil. This product will be shear-stable, wet-clutch compatible and capable of staying in service longer than mere mortal engine oil. Ideal for applications where service is infrequent.

About AMSOIL 20W-50 Zero-Turn Synthetic Hydrostatic Transmission Fluid

Several common zero-turn lawn mower brands such as Hustler, Gravely, Cub Cadet, Wright and Scag require a 20W-50 oil in their hydrostatic transmission system. This specialized hydraulic oil will be a step up from 20W-50 motor oil and a giant step up from conventional fluid. Expect cooler pump temperatures, longer component life and consistent transmission performance.

Maximizes Mower Speed & Responsiveness

In many zero-turn mowers, oil pressure drives the wheel motors. Fluid that fails to protect against wear can cause the tight tolerances in the wheel motors to widen, which reduces oil pressure and erodes speed and responsiveness. Fluid that thins at high temperatures can have the same effect. AMSOIL Synthetic Hydrostatic Transmission Fluid contains high levels of zinc-based anti-wear additives to help maintain those tight tolerances, while its synthetic base oils naturally resist viscosity loss in extreme heat. As a result, it helps maintain mower speed and responsiveness for increased productivity.

AMSOIL 20W-50 Synthetic Hydrostatic Transmission Fluid is specifically formulated to deliver smooth, responsive operation in zero-turn mowers, stand-on mowers and other equipment professionals rely on to make a living.   

• Fights wear for smooth, responsive operation   

• Purpose-built to outperform motor oils      

• Resists high heat and shear
