Customer Ratings & Reviews

I am switching my can am spyder and the dodge 5.7 to the 5-50 signature series oil. It is rated about the oils I am currently using. It is also slightly cheaper when purchased by the case.

I have been running Amsoil products for over thirty years and they have never let me down! This oil holds up through all extremes and after 6k miles on it almost drains looking clean. You cannot go wrong with these products. It only cost a little more to go first class!

About a month ago I got my pickup back from Hennessey Performance. They lifted it 6" and installed a Whipple supercharger on it. The recommended oil to be used is 5W-50. I have heard Amsoil is the best oil out there, and Hennessey recommended it as well. I have decided to use Amsoil in my Ford pickup and also my Audi car as well. I change the oil every 3000 miles or so and will expect the oil to work it's magic throughout the life of the cars. I will let you know how it works out.

Got what I wanted in a couple of days. Amsoil is the best

Great products, I’m a customer for life

it's the best engine runs very good

I have been using Amsoil products for a few years and am completely satisfied with the quality and performance of their products.. Thank you, team Amsoil, and keep up the good work.

Since the first change oil i made with AMS oil i notice the engine of my car is more quiter than before and also gets more mileage than my older engine oil i totally 100% recommend to all my friends👍👍👍

I have been using Amsoil products now for about 4 years primarily in my wife's Subaru. I use Amsoil engine oil and the CVT oil for the transmission and honestly the CVT oil cost me less than the CVT oil from Subaru. The only reason I don't use Amsoil in my other vehicles is because they are all older and they all use oil but for newer vehicles it's the best thing out there.

I haven’t found a product that holds up to the extreme conditions of a direct injection, turbocharged engine. Signature series oil retains its ability under high heat to provide superior protection. Lesser oils evaporate and shear under pressure, oil is inexpensive compared to an engine rebuild. I can’t recommend this product more.

Switched to this in one of my vehicles, great oil, stays cleaner longer than oem oil

Great oil, the Best!!!! Engine run smoother, A++++

it's the best

I won’t put anything else in any of my cars. Always works flawlessly. Nothing else needs to said because it just works. Worth every penny.

The product's from amsoil are the best in my opinion. I run it in all three of my vehicles.

Best oil on the market. Worth every penny. My grandfather used it and got me to use it. Glad he did.

Simply the best oil that you can put in your engine.

Used AMS oil for years, so has family! Never been disappointed!
