It is the best oil I have used. I feel more than confident my twin turbos on my 3.5 eco-boost are well protected. The proof of this occurred when my engine went in for warranty work for leaks and timing chain issues. The manufacturer was suggesting I was not taking care of the engine, but during teardown, the engine was perfectly clean with no trace of varnish. When asked what I use, there were no more questions and the warranty went through! I also find the engine starts and runs quite smoothly during the cold weather months with no loss of oil pressure. Combine this with the Amsoil oil filter, you habve a winning combination to protect your motor!

My 6.4 hemi runs smooth and quiet with it. Hoping for many miles out of it using amsoil

Been using Amsoil for 20 years+ exceptionally satisfied

Thought I was to get a free headlamp which I did not receive. Other than that everything was good

Best oil to put in my car! 10/10

No issues so far. Been using this oil for 50000 miles. I do change the oil when the car says 25%. Filter fits perfectly.

I know this is the best oil for the simple reason I put20,000 km on this oil and it’ll come out cleaner than any other synthetic oil with only 5000 km on it

amsoil is th oil I run in diesel trucks dieselgenerators boat and hotrod

AMS oil is second to none you can feel the power you can feel the difference for my 2007 Chevrolet 1500 Silverado Classic

Feel great about product

I swapped to Amsoil in my Jeep Grand Cherokee L and it is working out great. I’m getting way more life out of the oil and cost efficient in the long run.

I love having all my oil in one big jug as opposed to several quarts. Shipping from Amsoil is always top notch and speedy.

Maintaining a vehicle with the goal of longevity requires researched, proven, and quality products. Everything Amsoil exceeds every expectation for durability and protection.

I have used Amsoil for over 30 years and swear by it., My background is in motorsports and I have witnessed the advantages of a synthetic motor oil many times. I like the ashless makeup of the oil

Mon moteur roule beaucoup plus doux malgré ses 200 000km. Il ne sent plus l'huile brûlée lorsque je remorque et en bonis la consommation d'huile entre les vidanges a chutée de moitié!

I have been using Amsoil since 1978 when my dad bought a new chevy Caprice Classic! chevy's (corvette's), fords, VW's, Mitsubishi's, dodges, Lincoln's, and others have been treated to Amsoil's technology with great results. Less oil consumption, better performance, Less drain oil to the earth and increased longevity for engine's, transmissions and differentials.

Of all the synthetic oils that I used in the past this one has the quietest engine noise. I’m also getting a little better mpg on my GT350.

Delivered as promised.

I have used Amsoil products for many years and will never stop using them.

I have used this oil in my 2016 Silverado for 5 years. I change it when the display says and never add any between oil changes. I’ve been very happy with this oil.
