Customer Ratings & Reviews

Motor has 283 thousand miles on it and used the high mileage for the first time and the motor sounds great don’t even hear it running when you’re sitting inside am using it from know on.

I have used this product for several years in my 3 vehicles (all pickups or SUV's), and all of them over 20 years old. They all have had zero engine issues related to lubrication and they all have over 150K miles on them. I can highly recommend this product for any vehicles that have high mileage and follow the manufacturer's oil change/mileage requirements.

i use Assoil for both of our autos and also use it for my moms vesicle. vie been using it for years without any problems.

Started using this in my 2013 Ford Flex .. I have 150,000 miles on it.. I use this so I only have to change once a year

I am a crop insurance adjuster. I consistently drive thru blown out dusty fields, dusty dirt county roads. My Chevy is constantly working. This oil seems to be doing a really good job. I also have shut the AFM Off on this 5.3. Which also helps

This is excellent motor oil.

Great.!

All good!

I’ve used Amsoil for 40 plus years now it is an excellent product . I’ve recommended it to friends for years . My two sons use it also .

product was good only wish it came in 5 qt. bottles

Never been disappointed with Amsoil oil or any other product

Arrived quickly as does everything I've ordered from Amsoil

Given the properties of full synthetic lubricants compared to standard petroleum products, I would never consider going back to that old standard and with Amsoil's solid reputation for high quality products, they will continue to be my first choice in synthetic lubricants.

Noticed a big difference in noise and fuel mileage has increased. Prompted delivery with a good price.

Great oil a friend recommended to me and I’ve used and haven’t had an issues

Excellent oil for my Explorer. I ran it 11k miles on lest oil change.
