Customer Ratings & Reviews

I have a Roush Stage III mustang with 750 hp I would only trust it to Amsoil

Makes it easier changing out the oil less frequently without any loss of engine degradation.

Was a "FULL SYNTHETIC" for a long time, maaan was I wrong. I drive a v8 and I've switched everything to AMSOIL, what sold me was using this oil on my wife's Camry, 3 days after changing the oil using Amsoil, she asked what I did to it. I asked why and she said : it runs soo smooth, I was sold switched everything out immediately motor ,trans and differential on both 2016 Camry and 06 Tundra 05-w30. Thank you Amsoil "the best"

Been an amsoil customer for years. From quality oil to customer service Absolutely Top Notch!!! I use signature series amsoil in everything I own. Flawless Victory

I’ve been using this oil for over a decade in an ‘06 Tundra, ‘09 CRV, and ‘10 Infiniti G37. These vehicles continue to perform as new and do not use any oil. I’m convinced this product is superior to all others.

love it

I have used Amsoil Oil for a Number of Years. In my 2003 SVT Focus with 346,500 Miles on it and a 2011 Saab 9 3 . Both Cars are still running good with no Engine Teardowns. I believe in Amsoil Oil Products. You would have to tear down Engines to see what my using Amsoil Oil has done.

I like the oil. Mechanic recommended a while back.

The only oils I use. Always the best.

I have been using 5w-30 Signature Series in my 2013 F150 Ecoboost with 105,000 miles. I bought it with 51,000 miles and have been using this oil since. I can definitely notice the difference in how it feels and how quiet the motor is. I used to be a Mobil 1 guy but Amsoil is my choice now.

Awesome product, I’ve been using it for years….. Highly recommend!

First time using this oil, have complete faith in it, as all the other Amsoil products I've used worked beyond expectations.

I have been using AMSOIL in my 2022 Bronco since the 1st oil change at 5,000 miles. I wanted to use true synthetic especially since the 2.7 uses turbos. Not a hiccup to date. I am certainly a customer for life. This oil is amazing.

Do the math. Works great for me. Thanjs

Longest lasting & full synthetic! If you're living in cold climates… this is the go to

Excellent oil

I’ve been wanting to get this stuff in my 17 Sierra Denali and I’m glad I did. We get stupid hot heat here every summer and I need superior protection. I’ve been using the Costco Kirkland Oil for the past two years which ain’t bad oil for the price. Amsoil is by far the best stuff out there. I did noticed a little bit of throttle difference right off the bat. My engine runs so quite I can’t even tell it’s still on. Using the the signature series I know I can go a lot further now between oil changes. The filter you get with the kit is by far the best one out. It’s made very well. Will change my transmission fluid with the Amsoil fluid when I do my next change. Highly recommend.

Have a 21 ss camaro oil options were thin so decided to try this product. Only have a couple miles on oil change but so far so good

This is hands down the best oil I have gotten for my Supra. Oil flow is great and pressure is exactly what you would want. 10/10

I was recommended do use this oil in my truck by my mechanic I was kind of hesitant because of the cost of the oil. But once I started using this all in my truck, it is amazing. The difference in the performance is night and day.
