When AMSOIL developed the world's first API rated synthetic motor oil in 1972, new perameters for motor oil performance were established. AMSOIL motor oil outperformed conventional petroleum motor oils on all counts. Today, virtually every oil manufacturer has followed AMSOIL's lead and offers synthetic motor oils of their own. What can motorists expect when they switch their vehicles to AMSOIL?
Know the facts! AMSOIL will save you money.
Technical Properties of AMSOIL Motor Oils

Immediate start-up protection. You will experience immediate startup protection. Sixty percent of all engine wear occurs at startup. AMSOIL motor oils use high polarity base stocks and special anti-wear agents that form a thin film that clings to engine parts, preventing metal to metal contact. AMSOIL motor oils also lubricate vital engine components by quickly flowing through the engine immediately after startup.

Higher engine rpms and more power. AMSOIL synthetic motor oil reduces friction more effectively than conventional oils, so engine bearings rotate easier. This saves energy and conserves fuel. When the engine doesn't have to work as hard to move its parts, that power can now be used to drive the vehicle. Many new AMSOIL users report their shift points actually decrease due to the added power their engines experience.

Increased fuel efficiency. Since AMSOIL synthetic motor oils create less friction, they also help reduce fuel consumption, increasing a vehicle's fuel economy significantly. Operating with AMSOIL, the engine doesn't have to work as hard to turn the wheels, so it takes less fuel to run.

Lower tempertures. AMSOIL motor oils can reduce excessive operating tempertures of oil sumps by up to 20 degrees F compared to conventional motor oils. Friction generates heat and since AMSOIL motor oils reduce friction, less heat is generated. AMSOIL motor oils also carry heat away from the engine more efficiently than conventional oils to further enhance the cooling process.

Easier starting in cold weather. Conventional motor oils contain wax impurities that cause the oil to thicken at low tempertures, which slows the flow of oil through the engine at startup and promotes premature wear. They can thicken to the point where the engine won't even turn over and start. AMSOIL is pure and contains no wax. AMSOIL will pour at 60 degrees below zero. Engines start in cold weather as if it were summer. AMSOIL eliminates the need for block heaters. As users of this fantastic product know, in the winter you turn the key and go, no warmup needed.

These are just the immediate benefits from AMSOIL, long term your engine will last much longer, you'll have less time in the shop, and your vehicle will run like new longer. No matter how you look at it, AMSOIL saves you time and money.
