AMSOIL Dealer Louie A. Schwartz owns a 1986 S-15 GMC pickup with a 2.5 liter, 5 speed setup. He drained the factory filled petroleum oil at 40 miles and replaced it with AMSOIL 10W-30 Synthetic Motor Oil. As of February 2001, the engine had over 341,480 miles. Even more amazing, the oil has never been changed, a feat made possible with the use of an AMSOIL By-Pass Filter.

Schwartz uses the By-Pass Filter in conjunction with the SDF-23 Full-Flow Oil Filter and reports no major repair work has been performed on the engine, running gear wheel bearings or steering ball joints. His fuel mileage exceeds manufacturer expectations, reaching 24 mpg in the city and up to 32 mpg on the road.

Oil analysis test results confirm that Schwartz’s engine is in tip-top condition, a significant selling point for him. In fact, Schwartz has over 150 AMSOIL By-Pass Filters installed on his customers’ vehicles, and he estimates that between he and his clients, they have accumulated over 14 million vehicle miles. With the use of AMSOIL Multi-Purpose Grease, Schwartz has kept the steering, ball joints and front wheel bearings in as immaculate condition as the engine, proving that using the full line of AMSOIL products significantly extends equipment life.
