How to save money on fuel with AMSOIL

It does little good worrying about whether fuel prices will go up or down. Very few people have control over the price of fuel at the pump. What you should focus on, then, are things you can control. 

Foremost among these are the lubricants you use in your engine and drivetrain. Synthetic motor oils, transmission fluids and gear oils have a proven reputation of increasing fuel efficiency. AMSOIL has been the leader in synthetic lubrication for automotive service since 1972, hence its name “The First In Synthetics.” Compared to conventional petroleum based lubricants, AMSOIL Synthetic Motor Oils yield significant increases in fuel economy.

Not everyone is able to downsize their vehicle every time gas prizes go up, but whether you downsize or not, you’ll want to switch to AMSOIL synthetic lubricants for more efficient, cleaner engine operation.

Know the Facts, AMSOIL Saves You Money! AMSOIL extended drain intervals mean fewer oil changes, long term savings and convenience.


Ten Reasons Why You Should Switch to Amsoil

    1. Offers the latest technology for today’s engines.
    2. Dramatically extends oil change intervals.
    3. Less oil used with extended drains means less oil disposed.
    4. Increases fuel economy as much as 2 – 5%.
    5. Reduces engine temperatures by as much as 25 degrees F.
    6. Provides dependable extreme cold start protection.
    7. Offers the world’s finest engine and oil filtration.
    8. Reduces oil consumption and harmful emissions.
    9. Provides state-of-the-art additive systems and base oil stocks.

Engine Flush (AEF) 16oz

AMSOIL Fast Acting Engine Flush is made from a carefully selected blend of solvents and special cleaning agents that dissolve and disperse harmful deposits formed in the crankcase, cylinder walls, pistons and rings of an internal combustion engine. When used as directed, it cleans and restores operating efficiency to valves, valve lifters, rocker arms, and pistons for improved horsepower, fuel economy, and performance. Use before changing oil.

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.

Extended Life 5W-30 or 10W-30 Synthetic Motor Oil 7,500 Miles (XLF)

AMSOIL Extended Life Synthetic Motor Oils deliver exceptional protection for 7,500-mile/6-month oil change intervals or longer where stated by vehicle manufacturers or indicated by electronic oil life monitoring systems. They provide “Peace-of-Mind” for owners of modern vehicles where drain intervals exceed conventional oil recommendations of 3,000 miles.

Security beyond 3,000 Miles

AMSOIL Extended Life XL Synthetic Motor Oils exceed the current performance requirements for gasoline engines and deliver exceptional performance by controlling wear and maximizing fuel economy.

AMSOIL XL Synthetic Motor Oils are convenient and cost effective. They last longer than conventional petroleum motor oils, saving time and money. Motorists traveling 15,000 miles per year need only change AMSOIL XL motor oils twice, compared to five times for conventional 3,000-mile change intervals. While the initial fill may be more expensive than conventional oil, mile for mile AMSOIL XL costs less.

AMSOIL Extended Life Synthetic Motor Oils provide peace of mind. The oil drain interval recommendations for many of today’s vehicles extend well beyond the traditional 3,000-mile interval, some up to 12,000 miles with electronic oil monitoring systems. And unlike petroleum oils that have 3,000-mile maximum recommendations, AMSOIL XL Oils provide 7,500-mile/six-month drain intervals or longer where stated by vehicle manufacturers or indicated by oil life monitoring systems. When using AMSOIL XL Synthetic Motor Oils, protection and performance are not sacrificed with longer drain intervals.

AMSOIL Oil Filters, 25,000 Mile Filter


Cellulose and blended medias found in most oil filters have larger fibers than the synthetic nanofibers found in the Amsoil Ea Oil Filters. They also have larger spaces between their fibers. This causes contaminants to load in the depth of the media and plug the oil-flow path, resulting in higher restriction and less capacity. The smaller fibers in synthetic media also have a controlled size and shape. This results in greater efficiency and capacity than cellulose filters, as well as better durability. Amsoil Ea Oil Filters provide a higher level of engine protection, as well as extended filter change intervals.
