Good stuff. For do it yourselfer's.

Use it in diesel trucks and gas cars , over 260,000 miles on 2005 gmc suv running like i just bought it .

Greetings, I began using Amsoil in my Corvette 3 years ago. It ran cooler and noticeably quieter on cold starts. I’ve also switched my wife’s Traverse High Country and my Colorado Z71 pickup to Amsoil. Great product and I’ve converted others in our Vette club to make the switch.

AMSOIL provides the highest quality products. I never have to worry about my engine running at its best even if the oil level is low. My wife's 2005 4Runner has 390,000+ miles and still runs better than new!

I started using Amsoil in my bikes 14 years ago. After 3 oil changes and finding very little metal dust on my magnetic drain plug I was impressed. I now use Amsoil in everything I own.

Its a little more money than the Mobil 1 that I have been using in the past so hopefully the quality is much better

I run Amsoil in everything I own even my lawn mower.

Been using the SS for about 10 or 12 years now. No problems at all!

Decided to breakdown and try this oil based on price, quality, and talking with Eben over “Synthetic Oil Protections” on YouTube recommendation. I was relatively impressed with the quality of the oil as well as every single amsoil product I have bought. I switched to this oil mid February after using A couple other National brands, so far I’ve put about 1000 miles on this oil and it still looks like it came out of the bottle. Overall, I am highly impressed, I look forward to future products as well as witness the longevity of my vehicles and engines with prolonged use with amsoil products. Solid 10/10 from me.

Put this oil in my 2010 Chrysler Sebring. So far, so good!

Lifter tick is now a thing of the past, this oil certainly did the trick!!

Best oil out there hands down. I run it in every vehicle i own and every vehicle my boss owns and my sisters. Your vehicle deserves the best and the best is amsoil!!!!

I am in the process of working through a recall with Fiat regarding the over consumption of oil. I decided to make the switch to Amsoil and see if I could notice any difference. I am the original owner of the vehicle with 82,000 miles. I immediately noticed significant improvement over traditional brands including Mobil 1. The car performed better, was quieter and felt better lubricated with the Amsoil. It is worth the extra cost to have better than new performance.

Started using this oil after seeing numerous positive comments. I can honestly say my Toyota Sequoia runs better and is actually getting better gas mileage. I am on my third oil change since using AMSOIL 5W30 oil. My truck has better pickup and starts quicker as well. I would strongly recommend the use of this product.

Great quality oil. One of the best profiles on paper and in real world use. My truck runs smoother and a little cooler when I'm running Amsoil SS oil.

Don't buy inferior lubricants use the Best.... AMSOIL

Engine doesn’t shake and noise reduction has gone down. Riding smoothly. Didn’t realize how fast the difference would make. Doing it to all my vehicles.

Have been using this in my Alfa Stelvio since the first required oil change along with an Amzoil filter (longer than OEM) and it always seems to drain out rather clean at 3K intervals - considering now extending oil changes to 5K without worries
