The AMSOIL Advantage for your Recreational Vehicle

AMSOIL will save you money and give you the peace of mind that comes from using the best. Today's recreational vehicle engines are subjected to extreme stresses and high temperatures. They need more protection from heat than conventional oils give them. Conventional oils keep engines from failing most of the time, but there's a big difference between marginal failure prevention and the total wear protection that AMSOIL delivers! Your recreational vehicle is much more than just a motor vehicle. Trust your vehicle to the complete line of superior AMSOIL synthetic lubrication products.

Reduced Operating Costs
Greater Fuel Economy
Increased Equipment Durability
Extended Drain Intervals

AMSOIL Synthetic Motor Oils are ideal for gasoline and heavy duty diesel motor homes. These superior all-season lubricants minimize wear, increase fuel economy and improve performance through outstanding cooling, film strength and degradation resistance. And the synthetic formulation means you don’t have to change oil as often, further increasing your savings.

AMSOIL Synthetic Automatic Transmission Fluids

AMSOIL synthetic automatic transmission fluids are chemically engineered to provide exceptional lubricating protection and substantially longer service life than conventional petroleum fluids. They protect transmissions from the tremendous internal heat generated in the demanding, severe operating conditions of motor homes.

AMSOIL Synthetic ATFs resist oxidizing in temperatures that oxidize conventional automatic transmission fluids to protect clutches, planetary gears, valves, pumps and seals. AMSOIL ATFs’ excellent low-temperature fluidity provides smooth shifting and excellent fuel economy in cold temperatures.
