Customer Ratings & Reviews

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.

The first oil change after using Amsoil, my K&P oil filter had lots of gunk in it. The next oil change there was almost nothing. I'm hoping that it will take care of the bad oil delivery system in my Ford F-150 engine.

Best oil.

Look my friends, if you have searched for the best oil on the internet for countless hours as I have, AMSOIL is truly the best you can get so stop searching and just get it. I have tried many, many other brands and nothing I have ever used even comes close to AMSOIL. I use AMSOIL products in all of my small engines, lawnmowers, weed eater, pressure washer, generator, as well as my personally owned vehicles. This stuff is the real deal and doesn't evaporate, and does just what is it is supposed to do, that is, protect your equipment/vehicles. Don't waste your time and money looking elsewhere, just give AMSOIL a try and you wont use anything else. I have been down the road looking for the best protection and have finally found it in AMSOIL products. Thank you AMSOIL.

Amazing product I have been using Amsoil for years, my first car has over 200k and still running strong, when I bought my new truck I instantly went with Amsoil again and will definitely recommend it to all.

Superb quality motor oil, tops all brands by far. Would never use any other oil out there for my vehicle. Top notch oil.??

I started using this in my Harley Davidson Ultra Classic in 2006 and I could tell an immediate difference in the engine heat and noise. The engine was noticeably cooler and quieter. On my third Harley now and use this oil religiously. Will never use anything else.

Perfect for my two older honda. Both engine sound quiet. And they both have quick start up in cold weather in hot weather no problems. Better then mobil one. Brake down is way less

been using it for years. engine seems to like it.
