*OEM = Original Equipment Manufacturer

(1) Where the engine or operating conditions have been modified from the original manufacturers' design, no oil change interval recommendation is made. Oil change intervals are at the owner's discretion. Examples include the use of performance computer chips; modified exhaust, fuel or air induction systems and the use of fuels other than those recommended for normal operation by the manufacturers.

(2) Engines are in good working condition and within the factory design settings. Mechanically sound engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not overheat, do not have internal or external anti-freeze leaks and have a properly working emission control system. AMSOIL recommends repairs be made to malfunctioning engines prior to the installation of AMSOIL synthetic oils.

(3) Personal transportation vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.

(4) Extensive engine idling, daily short trip driving less than 10 miles (16 km), frequent towing, plowing or hauling heavy loads and frequent driving in dusty conditions. AMSOIL Ea™ and Donaldson Endurance™ full flow oil filters are designed for extended drain intervals. They stop smaller particles, have less restriction and last longer than regular filters. For best performance, use AMSOIL Ea or Donaldson Endurance oil filters.

AMSOIL by-pass oil filters are specialized for the removal of small, wear-causing dirt particles, thereby extending engine life. AMSOIL encourages using an AMSOIL by-pass filter system for maximum engine and oil life.
