Customer Ratings & Reviews

This is what I use in my truck

Great upgrade to oil changes in our 2003 Envoy.

Amsoil has always products that I trust! This is spec viscosity fits all three of my vehicles. Keep up the good work!

Used for my Harley, won't use anything else.

Best car insurance policy anyone can get

Amsoil offers best protection at reasonable costs. Don't have time nor $$ for car purchases every 3 years. Get the best car and keep it maintained with the best product.

Great oil! Use this in my '17 Silverado and it works flawlessly! Recently had the engine checked over and when they pulled the valve covers it still looked like a new engine! 10/10 will buy again

I switched my vehicles to full synthetic after trying it in my motorcycle. I now buy by the gallon and switched everything to synthetic oil, differentials, transfer case, etc. Gallon containers are convenient and economically priced. I'm amazed by the amount of residual deposits that are removed during the first switchover oil change in my vehicles that are were quite honestly, very well maintained.

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.
