Customer Ratings & Reviews

Simply the best bang for the buck. I have oil analysis to back it up.

I've been buying amsoil for 15 years. I've always been satisfied with all of the products and I've never had an oil related engine problem. Typically my mom goes up as well. I recommend Amsoil to my friends and they buy. Honestly there is no longer any reason not to. Synthetic oil is more expensive at your local Auto parts store.

Hands down the best oil on the market! Will never go back to the other stuff.

I use Amsoil in all that I own from vehicles, lawn equipment, generator and my motorcycle. Everything that I put it in runs great and the oil runs/ages very clean vs others I've tried. I use oem filters but with Amsoil the oil just doesn't seem to wear out like others if that makes any sense.

Excellent product.............................

Amsoil is the only thing I will put in my Vehicles. Why waste Money on oil that could possibly reduce the lifetime of your engine? Spend the few bucks more and save money in the long term.

Use it in all my vehicles. I beleive ya the only way to go

personal vehicle use, engine purrs like a kitten improved mileage

Been using Amsoil for 20 years and never had any engine problems.

I have used this oil for years. In my 06 Durango. It has over 230,000 miles and is still going.

have been using for years now always works better then other oil brands that i have used and its just great only having to do it once a year

I always use Amsoil in my vehicles and have had outstanding performance from it

I can only speak honestly and being that I just acquired the vehicle I changed the oil and transmission fluid recently to Amsoil. Both products seem fine but I cannot really say that they made any noticeable improvement in mileage or smoothness or anything else however I'm hoping they do provide the protection I'm looking for and continue to keep my vehicle running great for many years to come.

Amsoil is a superior product. I use it on all my vehicles and every time I convert a vehicle to amsoil it always runs smoother then it was prior to the swap.

I've been using Amsoil since 2009 in all of my power equipment from cars, motorcycles, lawn equipment, snow removal, generators and etc. I won't use anything else.

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.
