Customer Ratings & Reviews

Truck seems to run better.

The only product I will ever use in my racecars.

great products at a fair price-quick shipping

Great product. Well satisfied.

I replaced my engine oil in my 16 Mustang GT and the effect was substantial with a quitter engine and also it seems better heat protection with the weather being so hot

Works good, last long time

Same as the oil - wonderful product

2 mpg better than before

One of the best motor oils on the market.

use it on an older vehicle with high mileage and it works good

Since using this oil in both of my SUV's, they seem to be quieter and run better

Use in a 2013 Lincoln MkS w/ 3.5 ecoboost.

Love to price great oil will switch to the signature series on my next oil change

Great oil looks new every time I change it still.

I run between 6 to 8k a year on all of my cars and this oil gives me the confidence to schedule a yearly tune up with no signs of wear.

Does agreat job

I use Amsoil in my 2017 Subaru Outback and have us d it for many years. The XL 5W-30 is a great oil for me.

Good oil

Started using Amsoil awhile and have had nothing but success . The 4.2L engine in our trailblazer has over 200k miles it is quiet,smooth and uses 0 oil.I'm Happy!!!

I am an AMSOIL evangelist! Everytime I have an opportunity to talk with some about this product I do so. My car is getting better gas milage and running cooler.
