Original equipment parts and oils, (or aftermarket parts and oils manufactured to the minimum quality standards of O.E. specifications), are indeed fine quality and a motorist will usually have no problems using them. They are, okay.
However many motorists keep their vehicles for a long time, or drive their vehicles hard, or want something better than minimum performance parts and oils, recognizing the economy provided by longer lasting, better performing parts and oils. They want something better than just, "okay". So they install better tires, wheels, brakes, wiper blades, exhaust systems, headlights, air filters, sound system speakers and superior performing AMSOIL synthetic motor oils.

AMSOIL synthetic motor oils provide many more advantages to competing products than merely safe, long drain intervals, (up to 25,000 miles/1 year whichever comes first). Also, we must remember that drain intervals in and by themselves do not affect a new vehicles warranty. Extending oil change intervals will not in and by itself void a new vehicles warranty. To affect the vehicle warranty, it must be determined that the lubricant was directly responsible for the failure; if the oil didn’t cause the problem, the warranty cannot be voided, regardless of brand or length of time in use. This is the law. For further information call the AMSOIL Technical Department at (715) 399-TECH (8324) with questions or issues regarding warranties.
Some of the advantages AMSOIL synthetic motor oils offer vs. competing products are low pour points, for easy cold-temperature starting.
Low coefficient of friction for excellent fuel mileage.
High oxidation resistance for an internally clean engine.
AMSOIL products are designed to help vehicles and
equipment.
