Customer Ratings & Reviews

I run a car service in Boston. 2014 Cadillac XTS Livery Sedan went 596,000 miles, PLUS EIGHT YEARS IDLE TIME. I have picture of the odometer. Hard, high RPM driving. What a product!!

If you love your car, use Amsoil to protect your baby’s engine.

Extreme engine protection

Great product, highly recommend!

Best performing synthetic oil. Been using this in my Vette for many years. Noticeable reduction in heat, smooth running and protection at all RPM ‘s. So impressed that I started running it in my Pick Up and my SUV a couple of years back.

I say it’s the best ever and if you don’t trust me you have to trust Gale Banks.

With the oil my car work good and my savings is more than 50%.

After a year and 10,000 miles, this oil still looked great! The additional cost is negligible compared to the longer operating time and piece of mind knowing my engine is getting top tier lubrication and wear protection.

Thanks Amsoil for such a wonderful oil ..

Have used this oil ever since my truck was new 2019 ford f150 never a problem and engine runs asume even has a recall for cam fader and my friend is a service manager told keep using this oil and don’t do the recall I will be fine I am a fleet mechanic and don’t fix what is not broken will use the oil for the life of my truck thanks

Happy to be back on Amsoil with a new to me truck. Following an engine flush and the installation of Signature Series 0W20, the fuel economy is noticeably better and the engine sounds much better in the morning at cold starts. Not a placebo, I took the time to listen to the difference before and after. Moving on to a coolant change and transmission fluid now with Amsoil and see where that goes!

I'm presently running this oil in 5 different vehicles, the 5-20 and 5-30 versions in 3 others, and the 15-40 in 2 diesel trucks. My '08 Ram 5.7 has 332,000 miles on it. This truck pulls trailers, hauls load, and general every day driving. The oil pressure gauge sets on 55-60 lbs. All but a couple of the vehicles have in excess of 200,000 miles, all on factory engines. NEED I SAY MORE??

I think and hear from everyone else that the oil and filter are the best around for your car. But, still don't get complacent, change your oil when due. I have asked several questions via the web site. I never get an answer. It doesn't work. It should be taken off the site or have someone actually answer the questions.

Great product!

Good oil for my 2021 6.4 hemi 2500 will definitely be buying more!

Great oil use in all my vehicles transmission and engine even the differentials

Amazon roll is a great product a reduces friction and handles the power from my pro charged Shelby GT 350 perfectly I will continue to use this oil on going.

It's good quality oil I really do like the once a year oil changes

Just switched over to this for my 2022 Jeep Gladiator. Can’t wait to see how it will run now.

I’ve been using amsoil for years. Less down time and great preventative maintenance.
