Customer Ratings & Reviews

use amsoil for all your equipment don't risk it with cheap oils.

It’s the only oil I use in my Diesel truck and motorcycle, Go with the best do your oil changes , it’s the cheapest way to keep anything from happening!

I have been using this oil for some time now and find it to be the best lubricant for my diesel truck. Everything runs smoothly and quiet.

Oil used in 6.4 hemi and 6.2 gmc. Works very well.

We are off grid and have a diesel generator. I have used only Amsoil products for this essential equipment. Still humming after 7years of service.

I have a small horse farm. We use Amsoil Max duty 15w-40 in both tractors, both diesel trucks for long life and protection.

Ordered before noon and recieved the next day!! My 6.0 loves this stuff. Extremely happy with this oil!! Will continue to recommend to others.

I use this in my 2 diesel trucks and my welding machine

Best motor oil

Quick service , received oil in two working days . Been using since I purchased my vehicle with no issues . Thanks AMSOIL ..

After I order I received no confirmation email or updates on delivery date. Felt lucky when the order arrived. A bit more communication could go a long way. Like look at the successful online stores maybe.

I really can tell a difference using this oil vs any other on my 6.7 Powerstroke. It really runs very smooth. All I'll ever use for oil in my diesel. Very happy.

This product meets or exceed any diesel oil product out there! The only engine oil I will ever use in my truck period

I have a 2016 Silverado 2500hd LML. When I purchased the truck it had 120,000 miles on it. I have used this product since the first full service that I did on the truck. I change the oil every 5000 miles it runs quit and smooth. Although it is pricey I will remain using it

Very consent product. I know when a purchase this oil I'm getting a great product every time.

Quality product

Everything runs better with Amsoil oil. I use this in my Duramax.

Bought a new 2022 ram 2500 diesel. After a thousand mile break in I changed the oil too amsoil full synthetic six-time protection. I pull a trailer so I want the highest protection I can get in our very hot Redding weather. I will continue to use this oil in my ram!

I have used these oil products in my last 3 diesel trucks which don't get a ton of annual miles but I always use the best quality oil with long drain intervals which makes it nice.

Every 10,000 miles at the time I change my oil, doesn’t seem to be using as much as the factory oil usage. So that’s definitely a plus! Will continue to buy AMSOIL!!
