Customer Ratings & Reviews

Using the factory recommended oil for the LS powered Gen.V GTO. Also used 2 qts. more to top it off. No Doubt in my mind it's got the protection it needs now for the abuse I'll put it through this spring/summer and partial fall!

I bought this oil to use in my wife and I's 2025 Mazda 3 Hatchbacks, and to use in a 2025 Honda Ridgeline. I previously used it in a 2020 Subaru Outback Onyx Edition XT and the oil was phenomenal. I was running my Outback 11,000 miles between each oil change when I sold the vehicle back to the dealer I bought it from. I recently changed out the factory oil in the Mazdas from 500 miles to 800 miles to get rid of the break in oil. I will begin with running each vehicle about 7500 miles and then change it to see what the oil looks like. If the oil looks good, and I expect it will, I'll run it 8000 miles until I change it again. I believe this oil to be the best available in North America!

I Swap my 6.2 Silverado over to this and it's never run better

Best oil products

Been using Amsoil SS for my 2018 Durango GT and with 215k miles still runs great. I’m not sure if it because of amsoil but I have not had the common lifter failure on these 3.6 engines.

Only oil that will go into my 2021 Mustang GT. Amazing product.

Fast shipping great product

I recently changed the oil in my 2020 Ford GT. After reading several reviews pertaining to Amsoil I decided to give it a try. Next time I change the oil I’ll have it analyzed and write the results!

After researching different brands to use, came across AMSOil and saw they had a local distribution center near me. Ordered and picked up the same day. Great pricing through the membership, so changing all of my fluids over to AMSOil when needed.

Test after test after test confirms that Amsoil Signature Series is best oil to be putting in your vehicle, and it's the only oil I purchase for my Honda CR-V.

First time using this oil and I will forever use it from now on!! My motor sounds much happier with this oil!! Thank you so much AMSOIL!!!

Best motor oil you can buy! What a difference when you do your first oil change with Amzoil. Like two different vehicles!

Have used this oil on the wife’s Mazda CX-5 for three years. No problems, no leaks, great oil!

I run my TT 22' Mach 1 HP hard, and this oil protects my engine better than any other oil I have used.

Great product protects the engine accidentally and I will not recommend any other oil for your engine if you want to keep it running

Love it, makes the engine sound way less and oil temps be perfect!

best oil

I still have a hard time making myself drive the 25,000 miles between changes. Keeps engine clean, lubricated, and limiting wear.

I have run AMSOIL in my trucks and cars for 40 yr's without one problem

Quick shipping on this. And very happy with AMSOIL
