Customer Ratings & Reviews

I have used many brands of oil in my Rava 4, Amsoil has out did them all, best fuel mileage.

I used XL 10-30 in my 1982 Toyota P'up with 22R engine. She ran smoother, cooler & quieter. Used Amsoil in transmission & differential. Still running strong @ 344,000 miles!

Works as described...used in my 5.7 hemi and 3.6 in wifes journey both 12000km intervels... No problems

Nice long lasting oil, keeps engine running clean.

I have used XL 5W-30 motor oil in two vehicles for the last six years. Very happy with performance and wear. I would recommend this oil to everyone.

I am satisfied with the results so far in using amsoil and how well it holds up to extreme duty driving.

I have a turbo charged 4 cylinder Chevy which tends to run hot. I use Amsoil because the science says superior engine protection under high heat conditions. With 136,000 miles in 3.5 years have had no problems. I will keep using Amsoil.

I've used Amsoil products sense the 70's and they never fail to deliver. I have never had a oil related engine problem. Plus when everybody compares themselves to a product then which do you buy?

I have always used synthetics in my motors and never miss a beat when it comes to maintenance. I recently started racing RallyX with my wife and I have heard great things about Amsoil so I thought we would give it a try. I had no idea what we were missing out on. Basically it took the motors efficiency and turned it up to 11. Just changing to Amsoil from one race we were able to push our 88' Mazda 323 motor into a top 5 finish against cars as new as 2016. I now use Amsoil in all my cars and buy oil by the case.

This is the best product on the market

I use Amsoil in all my personal vehicles, and the results do add up. I can tell the difference right away. Pleased to be a Amsoil member.

5-6k mi changes and zero burn/ consumption 140 k miles and strong . Still clear at 5k change.

This oil has never let me down. I always average two miles per gallon better over other leading synthetic oils. Perfect oil for longer intervals and reduces O.C. issues. Great work again AMSoil.

I use Amsoil in all my vehicles-- from a 34 Ford to a new Equinox. Just sold a 97 accord with 300,000 miles on amsoil and engine was still like new. I also convert all to other amsoil fluids early in their life. Never had a failure of any component using amsoil.

I was introduced to this product (won a case)in the late 70s as a door prizes at a golf tournament. I got away from it until I bought my 2000 F150 when I worked with sone one who was a representative. It is the best product. I also put it in my wife's 1992 Toyota. When I had it (Toyota) torn down the shop couldn't believe how clean it was internally. I have not had my F150 worked on internally because it is still great with over 247,000 miles. It is worth the money and effort to use and change your own oil with Amsoil.

The best oil I've used in my lifetime!!!!

Use it in My 1999 Camaro SS....And my 1997 LEXUS FOR APPROX. 10 YEARS...189,000 And still going

I use it in two cars and it is the best by far and I will always use it.

I use it for the oil change on my 2001 VW Jetta TDI. Since I started using it, I've noticed my engine runs smoother, making less noise. And, together with a couple of other small upgrades to the engine, it also helps me get almost 5 mpg better than what it did before I switched oils in September of 2009. Ams oil is by far the best oil I've ever used on any of my vehicles.

I have used this product for the last few years. I think it is superior to regular oils.
