Maximizes Mower Life

Landscapers are under tremendous pressure to complete jobs on time and up to standards, which motivates them to seek products that help them keep their expensive equipment running at peak efficiency for as long as possible, especially expensive zero-turn mowers.

Continuous operation in hot, dirty conditions can lead to oil deposits and wear that can reduce engine compression, robbing it of power. Over time, mowers become less efficient, require more maintenance and eventually wear out altogether.

Commercial-grade formulation

Most small-engine oils Amsoil tested, are nothing more than re-labeled automotive oils, formulated with fuel economy in mind, not durability. Compared to liquid-cooled automotive engines:

Small Engines:

  • run hotter
  • operate under constant load
  • generate more oil-damaging contaminants
  • suffer from neglected maintenance
  • are exposed to dirt, rain and other extremes
  • are far tougher on oil 

AMSOIL 15W-50 Synthetic Small-Engine Oil

Amsoil designed this oil from the ground up specifically for small-engine dependability. Professionals can rest assured their engines are protected even during periods of extended use when there’s no time for scheduled maintenance.

This oil is built to solve the problems that plague zero-turn-mower engines, including:

  • wear
  • power loss,
  • oil consumption
  • harmful carbon deposits
  • stuck rings and valves

It helps landscapers and other professionals get more work done and save money.

Reserve Protection

AMSOIL Synthetic Small-Engine Oil is a long-life formulation. It has the ability to safely exceed original equipment manufacturer (OEM) drain intervals in the toughest conditions. Extensive severe-service testing proves its ability to provide service life of up to 200 hours/one year, whichever comes first. It provides an extra measure of protection when equipment goes longer between oil changes than is recommended by the OEM.


Use in small engines found in:

  • mowers (zero-turn, riding, stand-on, push),
  • generators,
  • power washers
  • other equipment that requires SAE 50, 10W-50 or 15W-50 motor oil.

AMSOIL Synthetic Water-Resistant Grease (AWG)

Heavy, wet grass can wash inferior greases from mower-blade spindles and casters, leaving equipment unprotected. Synthetic Water-Resistant Grease stays in place to lock out moisture and protect against wear, helping extend equipment life.

AMSOIL Synthetic Small-Engine Oil (AES, ASE, ASF, SEF)

Fights extreme heat for maximum cleanliness. It helps maintain power and extend engine life. We’ve tested dozens of small engines, and we’ve found that heavy deposits in the valve-guide area and piston rings are the leading cause of failure. Low-quality oils break down under extreme heat and form deposits, which rob the engine of power and eventually cause it to fail.

• recommended for up to 200 hours of use,

Zero Turn Mowers

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 (AHF) contains high levels of zinc-based anti-wear additives to help maintain 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.
