AMSOIL Benefits: Is it worth it? From an Ex-Ford Engineer

The Benefits of AMSOIL and Why I Choose Them

During my career as an Engineer with Ford Motor Co. engineering and testing cars, trucks, and performance vehicles, I was searching for a premium quality synthetic oil to run in my Bronco’s, F-Series Super Duty Power Stroke Diesel pickups, dirt bikes, snowmobiles, ATVs/SxS’s, farm equipment, excavators, track loaders, chain saws, generators, and small engines.

Industry Leaders Use It

While evaluating various product brands, I was involved in a joint special vehicle project with Ford and Roush Industries and noticed AMSOIL being used in a high-performance 800+ HP racing engine in a dyno cell.  

I inquired about AMSOIL with the Chief Engineer/Crew Chief in charge of the project, and based on our discussion, including his experience with oil in full-blown dragsters producing 1000 Hp per cylinder, I purchased AMSOIL Synthetic 2-cycle Injector Oil, Waterproof Synthetic Grease, and Synthetic Chaincase Oil from a snowmobile shop, installed it in my sleds and was highly impressed with the performance improvements and told all my snowmobiling friends and co-workers at Ford about it, they wanted to use AMSOIL also.

I contacted the AMSOIL Dealer who supplied the snowmobile shop that had been in the business for a long time and had extensive experience with AMSOIL while being in charge of equipment at a large municipality, registered as an AMSOIL Dealer, reviewed the product technical data sheets and specifications, purchased a large number of products, installed them in my vehicles and equipment and began evaluating and testing. This testing included tear-down inspections and oil analysis testing.

I Tested It In My Own Vehicles

I started with three original Broncos, then two 1987s. I did complete teardowns, engine transmissions, t-cases, drive shafts, axles, etc, inspected, measured, and analyzed the results after years of regular oil use, and then did full-blown restorations. Roush performed the machining, balancing, and blueprinting on the 302 Ford Hi-Performance engine blocks, cranks, heads, valves, connecting rods, and pistons, and more than two decades later, I haven’t had to replace or repair any parts on either truck and still run them hard to this day.  

That is a testament to the quality and performance of AMSOIL products. I also installed AMSOIL products in all my other power sports vehicles/equipment, F350s and F450 Power Stroke Diesels, excavators, track loaders, plow equipment, tractors, snowmobiles many small engines (chainsaws, etc).

Save Time & Money In The Long Run

The results are numerous, including the most important to me, massive time and money savings. Time is limited, and I don’t want to spend my limited time repairing stuff or replacing expensive parts that failed due to inferior quality lubricants.

I’d rather be out using my equipment to get a project or job done or having fun with them with my family and friends. Even on my Yamaha dirt bikes that I run hard, I’ve never had to replace a clutch or take an engine apart to repair or replace any failed or prematurely worn components; this includes my 2007 WR250F up to my newer YZ250FX and YZ450F, just performing routine maintenance and riding.

Part of that is a testament to Yamaha’s incredible engineering and manufacturing processes, and the other major part I attribute to AMSOIL products.

How Does AMSOIL Compare to Other Brands?

AMSOIL vs Motul

• In technical analysis, both brands demonstrate excellent high-performance characteristics, with AMSOIL showing advantages in thermal stability and high-temperature protection
• AMSOIL's significantly higher TBN (12.5 vs 7.9) than Motul's in passenger vehicle oils indicates superior acid-neutralizing capabilities and longer drain intervals
• While both are premium oils, Motul is notably more expensive across all product lines without offering significant performance advantages over AMSOIL

AMSOIL vs Liqui Moly

• Both produce high-quality synthetic oils, but, in our analysis, AMSOIL showed superior performance over Liqui Moly in key metrics like viscosity index and pour point across multiple oil comparisons
• While Liqui Moly excels in European-specific oils with approvals like ACEA A1/B1, AMSOIL's European line demonstrated broader manufacturer approvals (MB 229.71, Volvo VCC RBS0-2AE, etc.)

10 More Reasons to Switch to Amsoil

1) Synthetic Oil is Molecular Engineering for Modern Engines

New lean-burning, high-output engines often run hotter than 240° F. New electronically controlled automatic transmissions have less aerodynamic cooling and are extremely viscosity-sensitive. AMSOIL Synthetic Lubricants are chemically engineered for thermal stability. They deliver dependable, long-lasting performance and protection that helps equipment last longer.

2) Better Fuel Economy by 2% to 5%

AMSOIL synthetic lubricants have higher lubricity than conventional oils. That means less friction on moving parts, less heat, less wear and fuel savings averaging 2% to 5%.

3) Extended Drain Intervals up to 25,000 miles

Many AMSOIL motor oils provide more than three times the service life of conventional petroleum oils. The AMSOIL Signature Series - MAX Performance Engine Oils has a recommended service life/drain interval of up to 25,000 miles or one year. Longer drain intervals mean convenience and savings for AMSOIL customers and much less oil for disposal.

4) The Right Environmental Choice

Conservative estimates put the amount of waste oil dumped into the environment yearly at over 240 million gallons. When you use long-service life AMSOIL synthetic motor oils, the environment benefits.

5) Keeping it Cool

The superior lubricity of AMSOIL synthetic oils reduces friction, lowering lubricant temperatures by 20 to 50° F. AMSOIL retains its protective film on bearings at engine temperatures that destroy regular lubricants.

6) Reduces Oil Consumption

AMSOIL synthetic base stock and additive package work to keep it clean and running efficiently. AMSOIL lubes don't “boil off” like conventional petroleum oils. They stay inside your engine, lubricating, cooling, and protecting moving parts. Lower oil consumption and more efficient operations also mean lower emissions, another environmental benefit.

7) Unbeatable Cold Temperature Performance

AMSOIL Lubricants are synthetic and molecularly engineered with pour points as low as -60°F. This cold temperature fluidity gives motorists easier winter starting and fast lubrication to vital engine parts. Cold engine starts are responsible for causing 60% of all engine wear. Use AMSOIL to ensure your engine is protected during cold weather.

8) Finest Filtration In The World - with Nano Technology

AMSOIL oil filters and air filters are unmatched in efficiency and longer service life. Nano Fiber technology provides the absolute removal of 5-20 micron dirt particles. AMSOIL also provides a BY-Pass filter technology utilizing this revolutionary technology, extending AMSOIL synthetic oils even further with oil analysis.

9) Lubrication Excellence for a Wide Range of Applications

AMSOIL uses only the best synthetic base stocks and additives. AMSOIL Synthetic Lubricants and Filtration Products apply to various automotive, commercial, and industrial equipment. Being "the first in Synthetics" didn't make AMSOIL the best, but being the best has kept AMSOIL first.

10) Unsurpassed Customer Service

AMSOIL retains a staff of chemists, lubrication engineers, engine specialists, filtration experts, and lubrication industry consultants. They are available to answer questions and assist with special projects and applications.

What is the best motor oil?

AMSOIL is the best synthetic motor oil. AMSOIL synthetic lubricants are chemically engineered to form pure lubricants. They contain no contaminants or molecules that don’t serve a designed purpose. Their versatility and pure, uniform molecular structures impart properties that provide better friction-reduction, optimum fuel efficiency, maximum film strength and extreme-temperature performance conventional lubricants just can’t touch.

Does AMSOIL make your engine last longer?

Running AMSOIL in all of my vehicles, powersports machines, and equipment has helped me extend engine life and increase oil drain intervals. In my 1999 Ford 7.3L Powerstroke, I got over 68,000 miles in between oil changes by running the dual bypass system and sending the oil to OAI for regular oil analysis.
