Customer Ratings & Reviews

I started using this oil in 2009 in a Toyota Avalon with 230k miles. That same car now has 456k miles and runs as smooth as a top! I run the oil for 20-25k miles, changing the filter in the middle of the interval. I would not put anything else in my vehicles!

I have been told this oil is the best of the best. They say I can go 20k on an oil change. Do I trust that? Not really. But I try to use the best products that I can afford. Do I see or feel a difference? No. I just have to take their word on it.

If you want the best. This is it. Engine runs better

Best oil I’ve ever used. My vehicles love it too.

I use this in my Granddaughters Kia. She loves the fact of only one oil change a year. She is really busy with work and school . She does not want to be bothered a few months with an oil change!

I have been using Amsoil 5-20 in my 2014 150 and my wife’s 2013 Eacape since we bought them, 2015 & 2016 respectfully. The Escape will lose about a qt a year and my truck loses none! I swear by Amsoil, like a famous saying, I use that S!|t in everything!

Best oil for my acura

Great oil, plain and simple! 👍🏻👍🏻

As an automotive enthusiast since being a teenager, I have always wanted to use the best products when working on my vehicles. By doing most maintenance yourself, you assured its done correctly. Ams oil is known for its quality, and it's worth spending a little more knowing that you have a superior product.

Great product and fast shipping! Only run this in our Camaro.

I would and do recommend your products to all I can. It goes into my classic car and it's THE BEST!!!

I will only use this oil in my gladiator!

Been using Motorcraft oil in my F250 since I got the truck 2 yrs ago (290k miles) on it, til I started hearing knocking noises. Switched to Amsoil 3 mos ago and never heard those noises again. Expensive stuff but worth it to same my original 6.8 l.

See 0w- 20 review. Identical.

Amsoil is a quality oil. I use Amsoil in all my vehicles.

Obviously, I'm a bit disappointed that there is a filter shortage these days. Since we are only changing once per year, hopefully production will be in place for the next go around. Remember, AMS means aerospace material specification!!!

I switched to the signature series, now that I am getting my vehicle tuned, and going to be demanding alot more from it. Hope it treats my motor just as good, and the regular version of Amsoil I was using before the tune.

Have used Amsoil since 2009 for all vehicle fluid and could not be happier. 100% synthetic has yet to disappoint. Even if I forget to change an go a few thousand miles over a normal change.

Excellent motor oil …

Oil sample sent to Blackstone Laboratories to test for oil viscosity and engine wear. Part of the report said, "In short, your engine is wearing exceptionally well..." I'm very pleased and Will continue to use and recommend this product
