Customer Ratings & Reviews

I like using an oil product that I can trust, and this is it. I get better gas mileage and feel like my engine produces more power. Amsoil is a proven product that has stood the test of time. Thank you for offering this to us.

My 07' Toyota FJ Cruiser runs great on this product, much better than any competing brands. I use signiature series and put a high amount of miles on my truck in a very short time so I change my oil around every 5-6 thousand miles. Fast shipping. Good customer service. Definitely a quality product and a smart purchase for any vehicle owner.

This is a great fully synthetic oil that never disappoints. I love the extended change intervals that I get with this product. I can run this oil for extended drain intervals and not worry one bit due to the quality of this product.

01 civic ex honda,306460 miles,still gets 38mpg.had used 0-20 signature since 25,000 miles.The numbers speak for the oil.

I think amsoil products are pricing themselves out of the market. My last order for oil and filters was over 800.00 dollars and while I love the product and the cars have lots of miles on them. Almost 75.00 for and oil and filter change is getting out of control!!!! Going to be looking for an alternative for my next purchase

Regular oil for my truck.

This oil was purchased for a 2016 Corvette. They wanted the best, that's what they got

I have been using AMSOIL products since 1990. A mechanic introduced me and I have been using them in all of my vehicles ever since. As an example I started using AMSOIL in my 1988 4-Runner at 80,000 miles and at 225,000 no leaks and no burning. I have had occasion to call support to cross reference oil filters and have been very successful. Thank you!

Great product used it in a very high mileage vehicle haven't had any issues

Yes Amsoil products in all cars, trucks, equipment, motorcycles, and a boat. Never had a problem. Had to do a top end rebuild on a motorcycle with over 300 hours on it. Valves were worn out but, the cylinder looked brand new! Amazing product.

I first used Amsoil in my GMC Yukon XL. I immediately noticed the difference. More power and better gas mileage. Since then, I've been using Amsoil in every vehicle I own and everything I own that has a motor: tiller, lawnmower, chainsaw, trimmer, weedeater, pressure washer, 4x4 truck, small SUV and my GTO.

This motor oil provides superior lubrication, engine cleaning, and fuel economy.

The product holds up under extreme heat and saves you repair cost.

I ave run amsoil 5w30 in my 05 2500 silverado for 12 years. Still runs like it brand new after 150,000+ miles. I change oil about every 6,000 miles and never had any wear problems or loss of power problems.

The three most important things you can do for your car: warm it up, drive slowly as the moving parts warm up, and change the oil regularly. Since I wanted my Toyota truck to last, and I hate to change the oil, I use Amsoil. It's superior, and it only has to be changed once a year. Really! I ran fossil oil until after the engine was broken in, like 25,000 miles or so, then Amsoil for engine, trannie and differential since then. I bought my truck new in 1998, and it now has 344,000 miles on the original motor and trannie. Everyone who knows, knows Amsoil is far and away the best.

We must keep our vehicles well lubed-why would you not use the best quality lubricants known to man? I think of it as a no brainer.

I have been a preferred customer since 1989. All my vehicles, Cars and Pick ups have the 10w-30 signature since new. 200K miles plus on each, and still running strong. Replaced a valve cover gasket on a 1993 Chevy 4 cyl. with 180K miles, top of cyl. head brand new with no gunk. Was using the Amsoil By-pass system with this car.

Fuel and H.P. Gains Noticeable after changing over to Amsoil... I'll never Run Anything Else in My F-150 again!

I've used and sold Amsoil products for about 18 years exclusively, without one issue. At least 100,000 miles on three different cars and one almost 170,000. (2002 ML 320). Once a year oil changes are the norm.
