Customer Ratings & Reviews

This is way better than the oem oil your engine will last longer if you use signature series oil and change it on time.

Running this in two vehicles, Mustang GT and Jeep Cherokee. Vehicles run great.

I've been using this product for over 25 years and swear by it. I use it in all my vehicles and off-road toys. You can't beat this stuff.

Has helped keep my 5.7L Hemi happy, and on the road. Oil changes every 3 months at 7500 miles, and it stopped using oil after I switched to AMSOil. 125K on the engine now.

This is my go to for all my cars oil. Every car I have is using Amsoil.

Great service… Two days to receive the product Thank you AMSOIL

We've used this oil in our Explorer Sport since it was new. Eight years and counting and no issues of course. I'm sure there are other good oils out there but I consider Amsoil to be the best. It's all we use in all of our vehicles.

This is the only oil we've used in our F-150 since we bought it. Over 50k miles, including a lot of boat and camper towing and it's smooth as ever. In my opinion you can't do better than Amsoil.

Best oil I've ever used

Been using Amsoil on my Q50 and boy, keeps my engine like new👍

The BEST oil ⭐️⭐️⭐️⭐️⭐️

Best oil on the market hands down. Use it in everything from my vehicles to my motorcycle. You will notice a difference....I promise.

It's all I use, amsoil in everything

We have been using this product for 20+ years and really like its performance.

Who else publishes all the ASTM testing data for all to see, plus it clearly shows Amsoil is unsurpassed.

You may get a cheaper oil. But that is what you get for your money, cheap. Amsoil is top notch. Used in everything. Since used for the last 25 years I have not lost a motor, Trans, transfercase and differential.

What can I say, this oil makes my old 4runner run smooth.

Put this oil in all my lawn Mower and tiller had my push Mower over 17 years runs just like it did when I first bought it

Our fuel mileage went up a little bit after switching over to Amsoil Motor Oil. With the high cost of vehicles these days, why wouldn’t you use the best oil? Our cars run smooth and quiet and have never been back to the dealer for anything since the day we bought them. We are huge fans of the entire product line!

Everything is just better with amsoil Run longer with confidence I been using it on my lightly modified 2015 jeep wrangler jku with 35s I feel I’ll be getting the most out of my Jeep for years to come.
