Customer Ratings & Reviews

I like all the Amsoil products. They protect all my equipment. Use it in my Farm Tractor, ATV, motorcycle, Lawn Tractor, snow blower, chain saws, rototillers, etc.

Really feel the difference, when you add this to your gas!👍😎😲

Great oil been using it for a few years never had an issue with boosted applications. K24 Borgwarner S366 on E85 holds up well with E85 would recommend!

Here is my review. I have been a paying customer for more than 3 years. I own 2 Mazda CX5's and have purchased a lot of oil & filters, and paid for my membership. You used the Covid excuse to delete the required oil filters for this car without any options, forcing me to buy filters on the street while still paying my membership dues. Thanks!

I use this product in a new 2022 Chevrolet Tahoe. Engine seems to run quiet and smooth. With 4K miles on the oil, the oil still looks clean.

This product is awesome

Quality product. Expedition had 418000 when I sold it. Sporttrac has 347000 and going well F150 at 190000 purring.

Great Oil! Run it in my modified Camaro SS. Will never use any other oil!

Great oil

Beat oil I’ve ever used. I’ve put over 200,000 miles on my truck and it’s still running strong with no problems. Would recommend this product to everyone. Plus you don’t have to change oil as much.

Is good for high mileage engines

I have been using the XL synthetic in our Ford F-150 & Explorer since it was introduced and believe it provides great protection as well as no oil leaks after switching from Ford's synthetic blend.

My nine cars all have Amsoil without any failure. It’s difficult to evaluate a motor. Blind product as long as no failure. What I really like is the long change interval, since most my cars sit, and get little mileage.

After seeing a video on a youtube channel Project Farm, he ran a series of tests and Amsoil came out the winner. I was impressed, so I changed my oil for the first time with Amsoil and will be from here on out. I am trying out other products now, and have not been disappointed.

All the AMSOIL products we order are processed quickly and with absolute accuracy. We use AMSOIL in all our vehicles (boats, ATVs, trucks & SUVs)

Great product. I use Amsoil in all my vehicles.

I use Amsoil products in all my vehicles and ATV’s. Have been using this product for at least nine years. Great product!

After almost five years of Pennzoil and an engine slowly getting to be noisy first I ran the signature 0w40 and noticed a great improvement but decided to give the XL 10w40 a try for the summer camping season and so far this oil is working beautifully no MDS codes and finally an engine that’s as quite as the day I bought it. I do plan on running this from now on in my Ram thanks for a great product

Perfect for my 2018 GMC duramax.

I did not believe the ads about this oil. When I first started using it , I would send my used oil off to have it tested and the report always showed that it could have been used longer. This was back in 2005 so I started changing my oil at 25000 miles. I have been doing this in all my vehicles. I believe in Amsoil will continue to use their products. As for the Octane Boost, I am going to try this for the first time and will let you know any results.
