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.

Don't put clean oil in a dirty engine!

When an engine gets dirty, even regular oil changes can't help restore its operating efficiency. The detergen/dispersants in most conventional engine oils can't handle the abnormal amounts of contamination found in a "dirty" engine. The new oil becomes dirty long before it should, losing much of its ability to lubricate and protect your engine and actually accelerating the formation of more sludge and varnish.

In this age of longer recommended drain intervals, it is especially important to have a clean engine before changing oil. Using AMSOIL Fast Acting Engine Flush when you change oil is an excellent way to guarantee your engine stays clean. It has special solvents and cleaning agents that act fast but gently to remove harmful deposits that can cost you money in excessive fuel consumption and mechanical repairs.

AMSOIL Engine Flush is especially recommended for use before changing to AMSOIL Synthetic Motor Oils, assuring that these super premium long life oils provide the maximum protection and service life they are designed to deliver.

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). Do not overfill the crankcase. Idle the engine 15 to 20 minutes, then immediately drain the old oil and flush.

*Note: Engine Flush is not recommended for use in transmissions, differentials, air-cooled engines, engines that share a common oil sump with the transmission (motorcycles & ATV's) or engine not equipped with an oil filter.

2) INSTALL: Remove the old oil filter and replace it with an AMSOIL Ea Oil Filter. Ea Oil Filters feature advanced full synthetic nanofiber technology, making them the highest efficiency filters that are available for the auto/light truck market.

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 Ea Air Filter. AMSOIL Ea Air Filters represent a major breakthrough in filtration technology. The revolutionary nanofiber technology used in AMSOIL Ea Filters captures more dirt, holds more dirt and allows better air flow than conventional air filters. AMSOIL Ea Filters improve engine performance and help engines last longer.

A clean engine performs better and lasts longer. Clean your engine and keep it clean with quality AMSOIL products.
