Customer Ratings & Reviews

The best in the world! Nothing compares to AMSOIL!!!

Great price

Using this in 3.0 duramax and already noticing less oil usage than the ac delco recommended oil.

Amsoil 5w30 works better than factory oil. We need a 5w-40 for our here.? It's been over 100+ here since last of June.

Got the oil in a timely fashion. Easy to order online, don’t have to shop around to see if a regulsr store carries it or not.

I like the oil, i field the change

I love the product but wish it came in a 5 liter jug for less plastic waste. If it is available, it was not on the order site.

Just had my oil pump belt replaced at 150K and my mechanic noted that everything still is good as new when he removed the back plate from the motor. The little Durmax seems to love it just like every other vehicle I have run AMSOIL in. Been a customer for over twenty years and zero complaints!

There is nothing on the market that can even be compared to AMSOIL! Give your new vehicle the best and it will reward you. Your new car or truck needs AMSOIL to break in correctly! It is worth the extra cost because in the long haul it will save you money in repairs, and will increase your fuel economy!

I have a 2021 suburban with the 3.0 diesel and I have been getting really good results with the 5w30 diesel oil. With ACdelco 0W20 in 6500 kilometers I would add 1 litre of oil and blackstone labs report showed 68 parts per million iron and with the Amzoil 5w30 it uses no oil on 8000km and blackstone labs report showed 33 parts per million iron.

I’m using this for the 2nd time and I can feel the difference.

I watched a YouTube video where Gale Banks went to the Amsoil factory for a tour. If you are into quality products you should watch that video. Amsoil has top tier, quality products and you’ll know why after watching the video. I don’t know the finer details about one brand of oil from the next but I do know what quality looks like. Amsoil’s prices are very competitive too. I’m a super fan of this company. In a world where true quality is hard to come by these days it’s so nice to see that there are still a few places committed to excellence. Thanks Amsoil! Please don’t change!

It is well worth the peace of mind to trust one of my biggest investments to AMSOIL. Fast delivery, good support and top notch products are a must in my world.

Great product and in my book best oil to buy works great

I have been using Amsoil since 1977 and it’s done a marvelous job on everything I have owned. Highly recommend it.

Putting in my 2024 Chevy 1/2 ton.

It sounds crazy but my truck seems to run quieter and smoother.

Aucune consommation avec cet huile comparé à celui du dealer Chevrolet duramax 3.0l

Excellent Customer Service and Products. Best oil on the market.

0w20 was just to light of a oil for my 3.0 Duramax
