Customer Ratings & Reviews

I love this oil. It is makes sense when you want a guilty product… turn to Amsoil!

Great product, will definitely purchase again.

Awesome product would recommend to anybody

Use oil in a 2023 GMC Sierra with a 3.0 Duramax. I have used it since the vehicle was new. Fits OEM specs for 0-20. Great oil and we love it. Zee

Works good in 3.0 gm

Been using Amsoil in my 2020 Denali 1500 with the 3.0L Duramax since new. Change intervals between 3500 and 4500 miles. No oil consumption and all seems right.

Product is exactly what I needed for oil change on 3L duramax (2021 gmc)

Great product and fast shipping thanks amsoil

Amsoil is the only oil I trust in all my family vehicles.

Mon dmax ne consomme pas d huile rendu à 10k km sur la même huile

Got a new Silverado with the 3.0 Duramax and did the first oil change with the Amsoil 0w-20 diesel oil and noticed a huge difference. Truck ran nice and smooth as expected from Amsoil. I have used Amsoil for years and won’t use anything else !

Customer has been using product for 2yrs . No issues. He has recently bought a case of AMSOIL 0W-20 HIGH MILEAGE 100 % MOTOR OIL for an older truck ! I will be interested to hear, what He has to say about it ! Your customer service has always been great .

I have used this in my new GMC 1500 Denali with the duramax 3.0 liter engine since it was new. It meets the required dexos d and I love the packages.

Great oil, cheaper than the competitors at least here in Canada .. been using since my truck was new..

I have tahoe and Silverado both with 3.0 durmax this is the only oil I will use

This website is great even for an old timer like me its easy affordable and delivers within days to your door

I've been using this oil in my 2024 Silverado 3.0 Duramax since I did a break-in oil change at 592 miles and my truck has performed flawlessly. I only use Amsoil products in my vehicles.

Superior quality than OEM. Smooth engine sound. Feels like the engine is well lubricated.

I love the feeling that my new GMC 1500 Diesel has the best protection available including the filter.

I recently purchase this new 3.0 I6 Duramax. Chevy is very particular on what oil is used. My local dealer did not even carry it. AMSOIL did. 3rd oil change in 15000 miles. I dont know if AMSOIL helps the fuel mileage but it does not hurt it! 28.2mpg overall since I bought truck. I have been changing the oil myself. AMSOIL in my new Silverado 1500 diesel. Convenience of shipping, seems to work great. Im brand driven so Ill be sticking with it.
