Why Clean Your Engine?
Chances are, when your engine was new it delivered the power and fuel efficiency it was designed for. But now, as your engine accumulates miles, things are happening that are adversely affecting its performance. Slowly but surely, your engine is gathering harmful deposits that will eventually cost you money.

Even though you may follow a routine service schedule, your driving conditions may be far from routine. Stop and go driving, prolonged periods of idling, short trips that don't allow your engine time to warm up, towing a trailer, the ingestion of airborne dirt, fuel dilution, water condensation, and oxidized oil will eventually cause the formation of a thick, gummy deposit known as sludge. Settling throughout the engine, sludge will clog oil passages, restricting the flow of oil to vital engine parts, especially in the upper valve train areas.

1) Flush: To quickly clean residual sludge and engine deposits, AMSOIL Engine Flush is recommended: Change the oil filter and add the flush (about 10% of the oil capacity). Idle the engine 15 to 30 minutes, then immediately drain the old oil and flush.
*Note: Engine Flush is not recommended for motorcycles, ATV's or small engines.

2) Install: Remove the old oil filter and replace it with an AMSOIL Full-Flow Oil Filter. It is a high quality, state-of-the-art filter specially designed for today's long drain oils. And for the best possible protection, add an AMSOIL By-Pass Oil Filter to remove virtually all contaminating particles.

3) Pour: Fill the engine's crankcase with the AMSOIL Synthetic Motor Oil of the viscosity grade recommended by your vehicle's manufacturer. AMSOIL Synthetic Motor Oils are highly resistant to oxidation and provide exceptional detergent/dispersant properties, helping keep your engine free of further sludge and varnish build-up.

4) Change Replace your present air filter with an AMSOIL 2-Stage Foam Air Filter. AMSOIL Foam Air Filters trap and hold more dirt than conventional filters and still allow substantially more air flow. AMSOIL Air Filters deliver better performance, increased fuel efficiency, and lower exhaust emissions.
