For Heavy-Duty Diesel Applications
AMSOIL diesel oils are specifically formulated for hard-working, hot-running diesel engines to significantly reduce operating temperatures, inhibit the formation of engine deposits and provide excellent wear protection. For superior performance, better fuel economy and reduced oil consumption, treat your diesel to the best – AMSOIL diesel oils.
For Gasoline and Light-Duty Diesel Applications Signature
AMSOIL motor oils are ideal for gasoline and light-duty diesel motor homes. These superior all-season lubricants are designed to minimize wear, increase fuel economy and improve performance through outstanding cooling, film strength and degradation resistance. And their synthetic formulation means you don’t have to change oil as often, further increasing your savings.
AMSOIL Synthetic Gear Lubes AMSOIL
Severe Gear® 75W-90, 75W-110 and 75W-140 Gear Lubes • Synthetic 75W-90 and 80W-90 Gear Lube

Motor home drivetrains are often subjected to severe-duty service such as heavy loads, towing and extreme wind resistance. These severe-duty extremes can generate high temperatures and pressures, which can cause significant gear wear. AMSOIL Synthetic Gear Lubes (FGO, FGR, AGL) afford outstanding wear protection and extend gear life by protecting critical parts from deposits and surface distress even in sustained hightemperature service. AMSOIL synthetic gear lubes can help increase fuel economy in motor homes by reducing friction far better than petroleum gear lubes and offer outstanding rust and corrosion protection for motor homes stored for long periods. Severe Gear Synthetic EP Gear Lubes (SVG, SVO, SVT) are specifically engineered for high-demand applications, including trailer towing and heavy hauling. Superior lube film strength combined with extra additives protect gears and bearings from scoring and wear. Severe Gear Gear Lubes resist heat and possess excellent coldflow properties.
AMSOIL Synthetic Multi-Vehicle Automatic Transmission Fluid
Synthetic Multi-Vehicle Automatic Transmission Fluid (ATF) is chemically engineered to provide exceptional lubricating protection and substantially longer service life than conventional petroleum fluids. AMSOIL ATF protects transmissions from the tremendous internal heat they generate, even in the demanding, severe operating conditions of motor homes. AMSOIL ATF resists oxidizing in temperatures that oxidize conventional automatic transmission fluids and damage clutches, planetary gears, valves, pumps and seals. And with a -63°F pour point, the low-temperature fluidity of AMSOIL ATF provides dependable starting, smooth shifting and excellent fuel economy in cold temperatures. AMSOIL Synthetic Automatic Transmission Fluid is a universal, multifunctional fluid and is also recommended for power steering applications.
AMSOIL Formula 4-Stroke® Small Engine Oil
AMSOIL Formula 4-Stroke Small Engine Oil (ASE) is a robust formulation designed for high-temperature, severe-service operation of small engines where routine maintenance is often difficult or infrequent. It is formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE straight-grade viscosity requirements. AMSOIL ASE has a naturally high viscosity index and does not contain paraffin (wax). Its -38°F pour point and superior high-temperature performance make AMSOIL Formula 4-Stroke Small Engine Oil a premium all-season lubricant, perfect for the small generators found on most RVs. ASE
AMSOIL Filtration Products Donaldson Heavy-Duty Filters
AMSOIL offers premium Donaldson oil, air, fuel, coolant and hydraulic filters for diesel and heavy-duty applications.

P-Series oil and air filters offer premium filtration at a competitive price, featuring advanced media designed to trap wear-causing contaminants and extend equipment life.
AMSOIL Ea Oil Filters
AMSOIL Ea Oil Filters (EaO) feature advanced full-synthetic nanofiber technology, making them some of the most efficient filters available for the auto/light truck market. AMSOIL Ea Oil Filters have a far greater capacity than competing filter lines. When used in conjunction with AMSOIL synthetic motor oils, Ea Oil Filters are guaranteed to remain effective for 25,000 miles or one year in normal service and 15,000 miles or one year in severe service, whichever comes first.
AMSOIL Synthetic Grease

Greased bearings and linkages endure heavy loads on RVs. In addition, wheel bearings, Ujoints and suspension points are extremely susceptible to the harmful effects of dirt, water and mud. AMSOIL Synthetic Greases are especially suited for all types of motor home applications. Their tough synthetic formulations provide outstanding protection against friction, heat and wear, even in high-stress applications. AMSOIL Synthetic Greases offer superior lowtemperature pumpability, resistance to water washout and thermal and oxidative stability.
Ea Air Filters
Motor homes are exposed to a lot of dust and dirt. Good air filtration is vital to keep abrasive particles from entering the engine and destroying precision components. AMSOIL Ea Air Filters (EaA) rank among the most efficient filters available to the auto/light truck market. Ea Air Filters’ synthetic nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50 times more dust than wet gauze filter media. AMSOIL Ea Air Filters have a service life of 100,000 miles or four years, whichever comes first.
AMSOIL Fuel Additives AMSOIL
Whether you’re crawling up a steep mountain pass or merging into traffic on an interstate, you need all the power you can get. AMSOIL fuel additives can give your RV that added zip needed for critical moments. Use P.i. Performance Improver (API), Series 2000 Octane Boost (AOB) and Gasoline Stabilizer (AST) for gasoline engines; Diesel Concentrate (ADF), Diesel Cold Flow Improver (ACF), Diesel Concentrate Plus Cold Flow Improver (DFC), Diesel Recovery (DRC) and Cetane Boost (ACB) for all diesel applications.
