Customer Ratings & Reviews

I started using aimsoil in my car a year or so after I bought it. I drive a lot, 400,000 + miles on my car at this time and still going! Know I use aimsoil in my tractor also.

Only oil I have used in over 45 years of changing oil, That after 18000 miles still has plenty of protection left in the oil. Got to use a good quality filter as well, but this oil is awesome

Pay a little more and get a whole lot. I use Amsoil in my transmission, rear diff and engine. World of difference. I track my car as well and believe me I'm hard on my driveline. Gears, transmission and engine perform at optimum levels with Amsoil and you are protected. If it's used in racecars it's for a reason.

I have used this product for years and now starting to use it in my lawn equipment. I have had no problems.

I have discovered about amsoil about 2 years ago, and from then and now. I have switched to amsoil for all my vehicles. Especially my 96 Jeep grand Cherokee. I had to change my oil every 2months because it was burning the oil really fast. Till i made the switch, 8 months and the oil is still in good condition. This product sure made my money's worth. I really recommend this brand of oil.

I've used Amsoil products for years. If you understand the product technical reports, You will use this oil and filter combination. Best for wear, cleaning and longevity I've ever found. Lubricity is second to none.

Use in both personal and now work vehicle. Can't go wrong with extended drain intervals, pays off fast.

This oil has made a noticeable difference in my hemi. It's made the engine quieter and given me better overall gas mileage. You can't go wrong with the right oil.

I always order signature series for every oil change on all my vehicles and very been disappointed with the protection.

Of course anyone who has done any research on motor oils realizes that AMSOIL motor oils are superior to anything else on the market. I like all their products however I am upset at their recent price increases. I'm not sure why they continue to raise prices as the majority of us retired people never get a cost of living increases in our income. Please don't tell me it's R & D or material and labor increases to justify the increase.

I run amsoil in every motorized vehicle I own...very happy with all products

I have been using Amsoil products for over 30 years I believe they are the best

I use Amsoil on all engines large and small. Top in its Class

So far so good. No problems. AMSOIL has came highly recommended from my research. I plan on keeping my vehicles for the long haul and it made sense to step up to a better oil for my 2015 silverado 1500 z71 and lexus rx350, both of which use the same oil.

I started using Amsoil several years ago in my 2-stroke YZ125 and was very impressed. Back then I was rather unfamiliar with Amsoil so I started doing some research on Amsoil and other competitor brands, because I only wanted to run the best lubricants in my equipment. What my research uncovered for me is what I now believe to be so great about Amsoil. Amsoil provides plenty of literature from third-party testing that truly separates their products from the rest of the field. Other brands will only tell you what they want you to hear, but what is great about these testings is that we as customers can see for ourselves side-by-side test results, and the results speak for themselves. In these tests Amsoil's products are put through the ultimate rigors and unbelievably harsh conditions and STILL protect against breakdown and wear. The one thing about Amsoil is you won't see expensive ads on TV about what the company's oil "can or will do" for your engine like the "Big brands",however, with Amsoil you can read for yourself from unbiased third-party test results that PROVE Amsoil's greatness over competitor brands. As you can tell I am absolutely sold on Amsoil now days and run it in all of my vehicles even my lawnmower and snowblower. With harsh MN winters I need the best oil to protect with cold start ups. I would encourage everyone individual who is new to Amsoil, or even a long time user, to take a look at some of the testing that has been done on their products. Read the results! If you're still not sold on Amsoil I'm not sure what else to tell you.

Long oil life, keeps me going longer without having to do oil changes, engine sounds " heathy " less valve noice.

Amsoil is great use it in everything I own.

I always do all fluid changes in our Jeeps, changed everything over to amsoil and have never encountered any problems.

I've been using Amsoil in my vehicles for over 10 years now and in my opinion it is the best and less expensive in the long run. Less oil changes, less maintenance and better gas mileage. Over 280,000 miles on my 2004 truck and does not use a drop of oil between changes. Would like to see more in and out oil change businesses carry Amsoil.

Love all the Amsoil products. They've kept my 10-20 yr old engines clean and functional in severe heat.
