Customer Ratings & Reviews

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!!!!!

Switched from Castrol to this.

Used this oil to replace Toyota WS fluid, unable to flush fluid on this particular transmission, so I’m replacing 4 quarts at a time (total system holds 8.3 quarts). On this first fluid replacement, shifts are more sluggish and less precise than with old WS fluid. My guess is perhaps the two fluids are not blending well, I hope it will improve with subsequent fluid change, which is four more oil changes, with 500 miles between each change.

It's worth it. Better mpg car runs smoother

Over past 40 yrs i have used/sold lots of auto related products and appreciate best quality. Amsoil has proven to me that i can trust its products and that im getting value.

I use this oil in my 2018 Ford Taurus SHO. With regular oil changes at 7500 miles the oil still looks like the day I put it in

Protect your investment use the best oil available.

Highly Recommended! Went from conventional to this for my 2002 Cavalier. It runs better and smoother. Will stick to this motor oil forever

Had a new motor put in my truck last spring wanted an oil I could trust to keep it running like new so my research lead me to Amsoil now my go to oil for all my oil needs.

I used Amsoil 30 plus years ago in my 2stroke dirt bikes always ran great, & have used there Oil on & off since/ for the last year I have joined & been using there Oils exclusively & Very Blessed .... Awesome Oil

Well I own 2015 CNG Impala. 3.6L naturally aspirated engine. I change my oil around 20,000 miles. CNG makes it more acidic, per amsoil. I've been running amsoil since the car had around 30,000 miles on it. (First year free engine oil changes) It now has 112,000. So far so good, no issues, engine purrs like a kitten, I am going to run this car, and keep it until it dies!

2.7 eco16 f 150 I want the best performance,reliability,and longevity out of my turbos so I run the best and that’s Amsoil!
