Customer Ratings & Reviews

I’ve been using Amsoil oil and products for more than 20 years. Never a breakdown, higher fuel mileage, quieter running and peace of mind.

I've been using Amsoil 5w30 (among other viscosities too!) for over a decade. When I first switched over to using it on my turbo Miata, I did a few Blackstone oil analyses at oil changes. After 5k miles there was plenty of oil life left & TBN! My friends laugh at me that I kept my OCI @ 5k miles, even though the Amsoil could easily do 10k miles, but its cheap piece of mind! Always recommend Amsoil to all my friends & family!

My order was delivered very fast. Thank you

The best oil on the planet

This in my opinion is the best oil on the market. I have used all amsoil fluids in my 1992 Harley and just recently bought a 1988 iroc that I will be changing all the fluids to amsoil.

tried this and some of the competitors 5w-30 synthetic oil, this stuff outperforms everything else by a mile.

Good solid trusted brand, with their preferred member discount it is very well priced.

Totally worth it. My engine runs way smoother now. I can even feel a difference when I downshift the engine doesn't seem to Rev as hard when I get into gear. On top of all that the highest average for my mpg has increased by a whole mile without having to chamge the way I drive at all. 100% worth it!

Best synthetic oil on market with best prices

Outstanding Products and Customer Service. Will not use any other oil products.

Wish I'd started using it along time ago

This oil hands down is my favorite and I will only use it why?because it is the truth!!!

I put this oil in my 2010 Subaru with 125,000 miles on it and I just changed it a few weeks ago. No issues it lasted a year and performed flawless! I can’t wait to put Amsoil in my 2021 Tundra! Just waiting for the free dealership oil changes to expire!

Our third vehicle uses 0W-20 synthetic Amsoil and nothing else! great gas mileage too!

Only synthetic oil I have used in both our vehicles for years now and am amazed at how clean it looks after an extended oil change!

Been using AMSOIL for over forty four years without any problems. I always drive my vehicles like I stole them. Not a better oil on the market. If it works for me it will work for anyone.

The best you can get!

Have been using in my 2004 Chevy Truck for 5 years or more and love it!

Fits perfectly with manufacturers requirements

As soon as I was due for my first oil change, I went with trusted Amsoil products. They recommended this weight in my current car. Even in the Texas temperatures this summer, the car has been performing better and better. On my third oil change now. Throttle response and torque feel great. Thanks for another great product! 12 year customer, will continue to use Amsoil signature series in all my vehicles.
