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!

I used this oil in my 96 Mustang GT and my wife's 2010 Hyundai Elantra GLS. They are both in the 100k mile range and they have protected my engines through harsh environmental elements in New Jersey. We are a four-season state and that means you need maximum protection for all temperatures AND driving conditions. I love Amsoil.

Expensive but worth it

Very stable oil. Did quiet my 4Runner engine. No more engine stutter, hiccup or hesitation.

Watch all the real world tests, Amsoil is head and shoulders above the rest of the competition when it comes to synthetic oil performance. Worth every penny.

For me the best oil for new and old Cars. Its have the best protección to keep youre vehicle in exelent condition.

Never had cleaner oil when due for a change..spend the extra money now and save money later..all I have to say

great product

Been using Amsoil for the past several years, simply the best there is.

Makes better fuel economy

Awesome product, it's all I use

GREAT OIL FOR MY PPV CAPRICE. THE CYLINDER DEACTIVATION WORKS FLAWLESSLY! CLEANS ENGINE LIKE I HAVE NEVER SEEN

Great oil for the extended mileage capacity that my cross country fleet demands. No more California expensive oil changes that I used to pay for.

This is just simply the best on the market.

Running this oil in my 19' mustang, first oil change. Oil pressure runs higher now after getting the Ford MotorCarp oil out after 3300 miles.

I've used Amsoil for a number of years now. I currently use it in my 2018 Corvette, and 2006 Diesel Dodge truck that I tow with. Even though my annual mileage for both of these vehicles is under 7,500 miles per year I still change the oil every year. I also just flushed and refilled my Corvette with Amsoil's DOT 4 brake fluid.

This oil is great and I use it in my srt 10 ram. In between oil changes I have noticed less oil loss and it quieted my valvetrain down a little. Overall great oil and I would recommend to anyone looking for a top tier oil.

Way better than any other oil I’ve used. Lower temps (4-5°F) smooth start/shut off
