Customer Ratings & Reviews

We have been using Amsoil's Signature Series oils for over 20 years. Amsoil has protected our vehicles so well that even after 200,000 miles there has been no engine oil consumption by our cars (5 of them over the years). This being said, we are EXTREMELY disappointed with Amsoil for refusing to manufacture 0w-16 oil in the Signature Series line. Of course the demand for it is not great right now. But for longtime Amsoil customers couldn't they small batches annually for us? Most who require 0w-16 oil, knowing it's limited availability would likely buy an annual supply each year. It's very disappointing for us who have come to depend on the quality of Amsoil lubricants.

My oil analysis prove that this is the best oil money can buy

Great Product, Works well. Very Happy with it.

So far everything is working good. No mpg improvement or anything drastic. As long as it keeps my engine lubricantes and clean then that’s all I ask for. We will see after a few more oil changes, which won’t be for a while using this stuff haha. Never got my free hat with the order though :(

Awesome Product!

This oil, (5w-30) is more recommend than the 5w-20. This has eliminated all the extra motor noises you don’t want, coming from your 5.0 Coyote

It is the best product I’ve ever purchased thank u all for a great lubricant.

Last oil change was AMSOIL 0-20 at 17% on 10K total mileage truck. Oil still looked and felt good. Carries good pressure despite the thin viscosity. Mileage is noticeably better, not sure if that is due to break in period or switching to AMSOIL

I have tried a few “high quality” oils on the market but just a few dollars more the amzoil SS is incredible, quiets the motor, runs smoother and all around just runs better… I will be doing an oil analysis on my next oil change to see how the motor is holding up… 2018 ford f150 2.7 ecoboost with 38K miles. I plan on keeping this truck for years to come and only want the best!!

The best oil made, trying after Penzoil

Good stuff got my truck going, and I need my change the crank shaft...

Engine run’s better. Better gas mileage. Change oil every 12 months or 25,000 miles. Totally worth it.

Amsoil is the best motor oil I have found. Not only in products but the best company overall. I’ve used just about all of their products and the results speak for themselves. I’m always amazed and that’s why I only use Amsoil exclusively in what ever I own. Awesome company!!

aok

Been using Amsoil for years. Wouldn’t change for anything

I love Amsoil it’s the best oil you can buy! Note that I’ve started with them I’ll never use another oil again!

As former aviation mechanic I am a true believer in synthetics and specifically Amsoil synthetics.

Best oil in the world! Gives me the best fuel mileage and engine runs quieter then when it was band new. I have use Mobile and Motul “Specific” and “Amsoil signature” oil surpasses them all.

Change once a year. Never an issue.
