AMSOIL, the Proven Leader in Motor Oils

AMSOIL Beats Mobil 1 Tests prove that AMSOIL provides superior protection than Mobil 1.

AMSOIL provides a wide variety of high quality synthetic motor oils tailored to fit the needs of your automobile, SUV, performance vehicle, motorcycle or 4-stroke engine.

When the first can of AMSOIL 10W-40 appeared on the market in 1972, it signaled the birth of an entire industry. AMSOIL synthetic lubricants have expanded the boundries of lubrication science and redifined the performance possibilities of modern machinery and engines.

AMSOIL will save you money and give you the peace of mind that comes from using the best. Today's engines produce more power from a smaller plant with a smaller radiator and a smaller volume of oil to cool and lubricate them. 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!

AMSOIL Series 2000 Motor Oils
Special synthetic base stocks blends and advanced additive packages found only in AMSOIL Series 2000 synthetic motor oils provide up to four times the wear protection of other motor oils. AMSOIL Series 2000 synthetic motor oils reduce friction for quicker engine response, increased horsepower and improved fuel efficiency.

25,000 Mile Motor Oils
AMSOIL 100% Synthetic Motor Oils are engineered to outperform all competitive conventional and synthetic gasoline engine motor oils and exceeds the higher performance demands of modern engines. They reduce heat, friction and wear for maximum power, performance and fuel efficiency. Clean engine formula resists high temperature break down that forms sludge and varnish. Provides low temperature fluidity for fast, dependable winter starts and immediate start-up protection. Exceeds the most demanding world-wide performance standards and meets warranty requirements for all domestic and imported passenger car engines, both turbo-charged and non-turbo-charged. Combined with our EA Oil Filters, AMSOIL Synthetic Motor Oils provide up to 25,000-miles or 1-year drain intervals and have been doing so for over 30 years.

AMSOIL XL 7500 Motor Oils
AMSOIL XL 7500 Motor Oils are made to deliver 7,500 miles or six months of service between oil changes. These oils provide outstanding wear protection and increased power, performance and fuel economy in high and low temperatures.

Motorcycle Oils
Motorcycle manufacturers want the best protection possible for their equipment, calling for rugged oils that exhibit high temperature deposit control additives. AMSOIL Synthetic Motor Oils are specially formulated with the best synthetic basestocks and high performance additives to provide tough lubricating protection for all four-cycle motorcyle and ATV engines in the most demanding operations.

AMSOIL Synthetic Motor Oils are formulated for both water-cooled engines and the unique demands presented by air-cooled V-twin motorcycle engines, including Harley-Davidson. Conventional petroleum oils break down and oxidize when faced with high temperatures, such as those experienced when idling in traffic, contributing to the formation of deposits, sludge and varnish. AMSOIL withstands oil breakdown and oxidation in high temperatures, holds contaminants in suspension and keeps engines running cool and clean.

4-Stroke Motor Oil
AMSOIL Formula 4-Stroke Synthetic Motor Oil provides second-to-none protection and performance in Yamaha, Suzuki, Honda, Mercury, Kawasaki, Arctic Cat, Polaris, Nissan and Bombardier motors and transmissions specifying 0W-40, 5W-30, 10W-30 and 10W-40 viscosity grades. AMSOIL Formula 4-Stroke Synthetic Motor Oil is also safe for use in wet or dry sumps and is recommended for manual or automatic clutches and with clutch plates.

AMSOIL Engine Fogging Oil
Two- and four-stroke recreational vehicles, hand held power equipment, small engines, construction and farm equipment are commonly operated seasonally or infrequently, then stored for long periods of time. During these periods of inactivity, and as a result of fluctuations in ambient temperatures, water vapor can form condensate within the engine. When this condensate comes into direct contact with steel and iron components, it forms surface corrosion on cylinder liners, piston rings, anti-friction bearings and steel/iron contact surfaces on rotational seals. Long periods of storage can also dry out cylinders, often resulting in permanent damage when the equipment is taken out of storage and dry started.

New AMSOIL Engine Fogging Oil offers superior film retention, providing long-term protection against corrosion and dry starts, extending engine life and reducing operating expenses. Its aerosol spray formulation offers easy and clean applications, while reaching more components and offering better distribution than straight motor oil.

AMSOIL Engine Fogging Oil applications include, but are not limited to, motorcycles, snowmobiles, ATV’s, outboard motors, stern drive and inboard marine engines, personal watercraft, lawn equipment, chainsaws, snow-blowers, portable generators, hand held power equipment, motor scooters, powered farm equipment, powered construction equipment, cars and trucks.
