Customer Ratings & Reviews

Best performing synthetic oil. Been using this in my Vette for many years. Noticeable reduction in heat, smooth running and protection at all RPM ‘s. So impressed that I started running it in my Pick Up and my SUV a couple of years back.

I say it’s the best ever and if you don’t trust me you have to trust Gale Banks.

With the oil my car work good and my savings is more than 50%.

After a year and 10,000 miles, this oil still looked great! The additional cost is negligible compared to the longer operating time and piece of mind knowing my engine is getting top tier lubrication and wear protection.

Thanks Amsoil for such a wonderful oil ..

Have used this oil ever since my truck was new 2019 ford f150 never a problem and engine runs asume even has a recall for cam fader and my friend is a service manager told keep using this oil and don’t do the recall I will be fine I am a fleet mechanic and don’t fix what is not broken will use the oil for the life of my truck thanks

Happy to be back on Amsoil with a new to me truck. Following an engine flush and the installation of Signature Series 0W20, the fuel economy is noticeably better and the engine sounds much better in the morning at cold starts. Not a placebo, I took the time to listen to the difference before and after. Moving on to a coolant change and transmission fluid now with Amsoil and see where that goes!

I'm presently running this oil in 5 different vehicles, the 5-20 and 5-30 versions in 3 others, and the 15-40 in 2 diesel trucks. My '08 Ram 5.7 has 332,000 miles on it. This truck pulls trailers, hauls load, and general every day driving. The oil pressure gauge sets on 55-60 lbs. All but a couple of the vehicles have in excess of 200,000 miles, all on factory engines. NEED I SAY MORE??

I think and hear from everyone else that the oil and filter are the best around for your car. But, still don't get complacent, change your oil when due. I have asked several questions via the web site. I never get an answer. It doesn't work. It should be taken off the site or have someone actually answer the questions.

Great product!

Good oil for my 2021 6.4 hemi 2500 will definitely be buying more!

Great oil use in all my vehicles transmission and engine even the differentials

Amazon roll is a great product a reduces friction and handles the power from my pro charged Shelby GT 350 perfectly I will continue to use this oil on going.

It's good quality oil I really do like the once a year oil changes

Just switched over to this for my 2022 Jeep Gladiator. Can’t wait to see how it will run now.

I’ve been using amsoil for years. Less down time and great preventative maintenance.

my sub forester was using 1 qt. of 0w-20 oil every 3000 miles. dealer said i didn't qualify for a top end rebuild. excessive oil usage was a problem for some cars; and was handled under warranty. i switched to 0w-30 signature AMSOIL.... the problem stopped. i have 96000 miles on my 2017 limited. i use maybe a 1/4 qt. every 80000-10000 miles ; after switching to 0w-30 signature.

Hands down Amsoil has the best oil and oil filters out there. I always use the engine flush first and then do the oil change after about 15 minutes of idiling. Then I change oil and filter, and even after the first oil change I did with the Amsoil products it was like my car was a new car. Now I drive about 1000 miles a week commuting to and from work and I used to worry about my car not making it one day but now with this oil I don't even have the littlest worry anymore. Will be changing the oil every 3000 Miles for the first 3 oil changes just to get my engine back in great condition and fully lubricated. After the first 3 oil changes I'll go to changing it 3 every 5000-6000 miles and I know now it will be completely fine. I've used all the best oils out there like motul, liqu-Moly, Royal Purple, Red line, Pennzoil platinum, and any other premium oil you could think of, and hands down nothing compares! Thank you AMSOIL! Nothing but the absolute best.

Been using amsoil in my tundra for 5 years. Truck has 140k miles and still running like new. Still do the oil change every 10k miles that's recommend by Toyota. Product always arrives quick, will continue to use amsoil for the remaining life span or ownership of the truck, and would recommend amsoil to anyone and everyone

I have been using this oil on my 2015 Lexus RX350 for 5 year and have had no complaints so far.
