Customer Ratings & Reviews

I have used Amsoil for over 30 years and swear by it., My background is in motorsports and I have witnessed the advantages of a synthetic motor oil many times. I like the ashless makeup of the oil

Mon moteur roule beaucoup plus doux malgré ses 200 000km. Il ne sent plus l'huile brûlée lorsque je remorque et en bonis la consommation d'huile entre les vidanges a chutée de moitié!

I have been using Amsoil since 1978 when my dad bought a new chevy Caprice Classic! chevy's (corvette's), fords, VW's, Mitsubishi's, dodges, Lincoln's, and others have been treated to Amsoil's technology with great results. Less oil consumption, better performance, Less drain oil to the earth and increased longevity for engine's, transmissions and differentials.

Of all the synthetic oils that I used in the past this one has the quietest engine noise. I’m also getting a little better mpg on my GT350.

Delivered as promised.

I have used Amsoil products for many years and will never stop using them.

I have used this oil in my 2016 Silverado for 5 years. I change it when the display says and never add any between oil changes. I’ve been very happy with this oil.

This oil definitely is everything they claim. I started using Amsoil in my Motorcycle ( Harley Davidson). In air cooled bikes oil is everything. And now use in everything I own. Never a concern with upper valve train quiet operation and increased free rpm. In my 5.7 liter hemi very noticable the difference in valve train quietness just like the Harley and Indian motors. Again you can't go wrong.

Only the best for my daily driver and my racecar. Great oil, great support. Great shipping time.

Had great results with the transmission fluid so since buying a new motor for my 2015 nissan frontier 4.0 engine decided to start fresh with this oil and will continue to use . Thanks amsoil.

I started using AMZOIL about 2 years ago, and I use 3 different types depending on which vehicle. I am a carrier technician and I am in my 50th year. I'm a believer in proper service and use this on all my vehicles. I started that after watching Gail Banks videos. Keep up the good work. Danny

My wife and I have owned an auto repair shop for 38 yrs. We have always been about quality. Now that we are retired, we want to give our vehicles the best we can. We are high mileage drivers. We use Amsoil products only. Of course nothing is an absolute guarantee. But knowing our vehicles are getting the best we can give is a real piece of mind. Thank you Amsoil for giving us your very best. Very very satisfied customer.

The Amsoil Signature Series oil is absolutely perfect. I change it at 7,000 miles. My Honda CRV runs very smooth. And gets excellent mileage.

Used in smaller cid engines and it works. Seems with running moderately to heavy and that real lubrication was happening. Oil change confirmed it.

It's watery oil that Toyota recommends.

What do you say about an engine oil, I’m not a petroleum chemist? I only use Amsoil engine oil in all my mobile equipment. After putting hundreds of thousands of miles on my cars and seeing the condition of the valve train, or cylinders when I have an oil pan dropped to change a rear main seal, for over 30 years it’s no contest. I don’t care what viscosity is required, if it’s Signature Series I’m confident in the protection. I don’t believe there’s any better.

I have been using Amsoil on my Ford Edge since the first oil change & I won't use any other oil. I love the pour point for this oil, the OEM oil had difficulty starting at -12C after sitting in a detached garage overnight. With the Amsoil it never had any problems starting even without being plugged in. Even with temperatures dropping to -38 outside.

Très bonne huile

I started using this in my Colorado with over 200K. It burns less than a quart after 6K miles. It doesn't seem to lose viscosity like I did with Pennzoil or Mobile 1.

I have been using Amsoil in all my vehicles for over 20 years with no engine failures, excellent fuel economy, and low wear numbers in oil tests. Plus the 25000 mile or 12 month change interval makes using Amsoil an easy decision.
