Customer Ratings & Reviews

It’s the best oil I’ve ever used . I run a lawn care business and use it in all of my equipment .

My Coyote makes 440hp at 8k rpm. AMSOil Synthetic is all it has ever had, or ever will.

I love this oil

Best of the best

At first I thought the thin disposable bag like container was gimmicky and just a way of cutting corners. But after using it on three vehicles I can say it was actually helpful. I end up having had very little mess and I didn't have to use a pump. Way to think outside the box Amsoil!

This oil is used in a vehicle that has 87,000 miles on it and it keeps the engine running great. I love this oil.

I use this oil type in both of my Toyota vehicles. I have watched many independent info videos on amsoil too. I will be a life long user.

I went and got the Oil change and as soon as I got in my car and drove. I can tell a whole heck of alot difference. This brand is used in all of my vehicles

I have just out this in a 2022 Colorado so no experience yet I also purchased dominator 15/50 for a camaro 10 second car I ran recently and I was amazed temperature runs cooler I have run this car fir 10 years with temperature a problem

Always ran RP thinking it was protecting my engine. Boy was I wrong. If I could go back Amsoil from day one. But one things for sure it will never have any other oil going forward. Try it! Factor life of oil, added protection and less oil usage. It's cheaper than any other oil

Best stuff I’ve found by far. Just wish it was sold in stores.

I switched from Mobil 1 in my 2005 Corvette Z51 Convertible years ago. It runs cooler and smoother. My buddies use it in there Vettes on the track and at the Drag Strips. They beat the hell out of there Vettes and never had any issues. I switched my daily drivers Colorado Z71 4x4 and my Traverse AWD High Country. I have converted other club members to run Amsoil in there Vettes. Love your products.

I purchased the signature series for two vehicles and both seem to be running smoother. Extremely happy will see in a few months how it holds up.

I will continue to use the diesel all in my trucks and I will recommend people that I talked to has diesel or gas engine trucks or cars to use them as our products you’re doing a good job keep up the good work

I've used this oil for the last 200,000+ miles in my 2003 Silverado (5.3L). 322,000 miles now and still going strong!! I use this oil in my wife's car also. I use most all their products, from gear oil and grease to the firearms lubricant. I'm an Amsoil only user from now on!

Ever since I put Amsoil in my truck, it's always runs smooth and lasts so much longer than the inferior oils. I will always use Amsoil!

2000 miles and still looks like brand new. So, my 2007 Dakota has 240,000 miles on it and every year I drain my oil, replace the filter, drop the pan & add crap Walmart synthetic oil for about 300 miles. Then I drain the oil, replace the filter & add the Amsoil. My truck runs smooth and quiet. BTW, I don't think I'll need to drop the pan anymore....this is the 3rd year using Amsoil and my mechanic told me that the pan & magnet looked the cleanest he's seen with an engine over 200k in miles.

Wrote wrong review on the ow-20 oil...it is this 5w-30 oil I have been using for my 2011 Chevy Cruze with 1.4 turbo. It does not use any oil between my 7 to 8,000 mile oil changes and I currently have 201,000 miles on the car.

I have been using this oil for over 25 years. My current car, 2011 Chevy Cruze, 1.4 turbo has 201,000 miles and does not take any oil between my 7 to 8,000 mile oil changes.

Been using it since 2014 in my Silverado change it once a year only 21,000 original miles no oil consumption , LOVE IT!!!!!
