I’ve been using this product for years and it’s the best product I ever used

Been running this oil in my 2015 Ram 1500 5.7L since I got it new. Now close to 100,000 miles and zero issues. Runs smooth and never had and oil leak. Will keep running this oil for the life of the truck.

High quality oil, no issues, been running in my 2022 Ford Ranger for 20k miles at 5k intervals

The only oil I use in my vehicles

I have been using products for 15 years and have never had an issue. Good quality and I won’t use anything else.

Been using AMSOIL products for years! The best out there!

Great oil works as it should

It keeps getting better every time I drive. No more Royal Purple for me. Jj

I've been an ASE certified master auto technician for 52 years, now retired and running my own small shop. I've gone through all the testing info and run tests of my own. Amsoil motor oils are the real deal. In my vehicles at least I've experienced reduced engine temps, better fuel milage, better winter start up etc. My entire fleet of vehicles have been changed over to Amsoil and will stay that way.

Turbo juke with lspi issues. Did an oil change with this and a throttle body cleaning and the car starts and runs like new again. No more stutter on a cold start or weird lag at hwy speeds.

It's nice knowing I've got the best oil in my toyota. I plan to make an already long lasting engine last forever if I can help it

Great product.

Hands down best motor oil

Good oil holds up well

Great OE motor oil from the best in the business.

Great product! Works perfect for what I need it for!

I use nothing but Amsoil products as they out preform all other products that I have used in the past. I just wish that US Accounting department could bill me right. I have had to call both times and have them adjust the amounts charged to my Credit Card

We had to do an engine swap and bought generic oil after install to test it out. Once it was driven a while we put in amsoil and the oil pressure increased significantly. That's why all of our equipment from compressors to trucks only gets amsoil. They are unmatched in every field.

I have a 2006 BMW inline 6 with 387,000 km for two years now. The seller changed the oil for me when I bought it. He used Liquimoly, I think. He told me it burned some oil. I don't drive it much so over one year I had to add oil a number of times. One year ago, I had it changed to Amsoil. In the past year, I only added one bottle of Amsoil. The previous owner is an automotive engineer, and he has a hard time getting his head around that switching to Amsoil reduced oil consumption by well over half. I don't understand the science behind it, but those are the facts, with similar distance and similar driving style over those two different oil brands.

Been using this oil in my Honda Accord for over a year now and the car is running as smooth as it every has.
