Mixing AMSOIL

AMSOIL Synthetic Blend 15W-40 is compatible with petroleum and synthetic lubricants; however, mixing the AMSOIL with other oils will shorten the extended drain period. Oil additives or after-market products are not recommended for use with AMSOIL Synthetic Blend 15W-40 Motor Oil.

New Vehicle Under Warranty

The use of AMSOIL Synthetic Blend 15W-40 Diesel Motor Oil will not void new vehicle warranties. New vehicle warranties are based on the use of oils meeting specific API service classifications and SAE viscosity grades. AMSOIL Synthetic Blend 15W-40 meets and exceeds all current API and SAE requirements (as labeled) and is perfectly suited for use in any new vehicle stipulating those requirements as manufacturer's recommendations.

Service Life

• Light-duty diesel engines, non-turbocharged diesel engines, heavy-duty diesel engines, turbocharged diesel engines, fleet vehicle engines and industrial engines: drain oil at intervals up to two times longer than those recommended by the engine manufacturer, or 6 months, whichever comes first if extended drains are supported by the findings of a used oil analysis program.
• Personal car and light truck non-turbocharged gasoline engines: drain oil at intervals up to two times longer than those recommended by the engine manufacturer or one year, whichever comes first.
• Non-commercial, turbocharged passenger car gasoline four-cycle engines, motorcycles, small off-road four-cycle gasoline engines, marine craft engines and infrequently used four-cycle gasoline automotive engines: use engine manufacturer's oil drain recommendations.
• High-performance or racing engines: drain oil at intervals determined by the findings of a used oil analysis program.

Change AMSOIL Full Flow Oil Filters at 12,500 mile or six month intervals, whichever comes first, in gasoline engines. In diesel engines change AMSOIL Oil Filters at 7,000 miles or six months, whichever comes first. Change other manufacturers' filters at the engine manufacturer's recommended filter change intervals.
