Customer Ratings & Reviews

Not my first rodeo with Amsoil. Ran it 30 yrs ago in my motorcycle... Decided to run it in my new Bronco Raptor. Won't run anything else in it.

I started using AMSOIL in my 1984 Z28, continued through all following vehicles we have owned. A '91 Silverado, '99 Z28, '04 Corvette, '04 Tahoe and our new '23 ZR2 Colorado. We have retained the Tahoe (seriously modified) and the Colorado. We sold the others. The common thing that has kept us using AMSOIL is that when I check the oil level, it is always full and still clean. We have had no weeps or leaks on any of the motors. Can't beat that! And I did and still do all the maintenance on all of them.

Does it's job, definitely improves performance and my car loves it

My mechanic had used this oil on my 2017 GMC Terrain a few years back and I’ve never had any issues with this product. It’s the only oil I’ll ever use and my new mechanic is a fan of this oil. Will be re-purchasing often from now on.

Great product and fast shipping will buy again

We bought my wife's Altima new in November 2013. Fall of 2014 I was doing my second oil change and switched to this product and have used it ever since. I change the oil/filter every fall and in the spring I change the filter and add some fresh oil. The car has 145k on it and still doesn't use any oil. It has changed me and I am now all Amsoil in everything I run.

Would definitely recommend and purchase again!

Would definitely recommend and purchase again!

This oil is worth the extra money, to protect the ridiculous amount of cash,We pay for our vehicles. Amsoil has never failed me.

great products, worth the extra $ for the piece of mind.

I ordered oil and a filter to change the oil in the LS3 in my C-10. It was shipped quickly and the gloves, filter and oil change sticker were a nice surprise.

Been a loyal user since the late 1980's and haven't used any other oil.

Great motor oil, helps with performance, it's a high end motor oil so you pay a little more. If you order the Jug it's 4 qts not 5qts. Amsoil is easy to order on line and fast delivery. They have a customer service and a tech cs too.

Was a bit skeptical like any other person when hearing Amsoil since some people say it’s overpriced and not worth it. Let me tell you something, haters gonna hate. You get what you pay for in this product! It’s crazy to say but swapping from oem to signature series on my wife’s 23 Explorer 3.0 with turbos, the motor idles smoother and quieter. It just feels and sounds more lubricated with less friction. Hoping this oil can take my 3.0 to last for years to come!

Best there is

I never had a single lubrication/valvetrain issue since switching to this stuff

Excellent product

Great oil, car runs great

I use the 0W-20 Amsoil Signature Series Synthetic Motor Oil for both our Cars.
