Customer Ratings & Reviews

this has been the only oil i have ran in both my f 250 from day one excellent product.Been using amsoil for over 35 years

Amsoil makes it easier than ever to find the right oil and filter for your vehicle. Fast shipping for top quality products saving you time and money than going to you local dealership.

I only use the best oil on my 2022 Ram 6.7L Cummins. Engine runs smooth

best oil in the market

Love the product and the website. I just wish we wouldn't have to go to the effort to add the gifts that we earn in purchases over whatever the amount is.. I know that seems like a small complaint but i'll give you the example. I ordered a couple of hundred dollars of product, thought i entered for the free gift (the lego guy) and realized that I didn't order it. I promised it to someone who collects lego and would now have to purchase it instead... Is there an idea that one could build points to purchase those items so even if you didn't remember to add it or you wanted something different like a toque for example they would be able to order that??? Just some feedback, than you for your consideration. Have a great year and looking forward to ordering more products in the very near future.

This is just my second oil change with absolutely and I got to say I am very impressed. Oil pressure is always steady.

My local dealership recently had to replace the upper oil pan gasket. When I went to pick up my vehicle, the mechanic asked what type of oil I used. He was extremely impressed by the internal cleanliness of my engine at 120,000 miles.

I am happy with the diesel max oil I have been using it in my dually for a couple years and decided to switch my 2021 jeep gladiator diesel to it also both of them run great I will stay with it because it works well.i will be switching my farm tractor over to amsoil.

Been using amsoil for years!! Hands down the best there is!

👍🏼

Only oil I have ever used in my 2016 EcoDiesel. Running strong with no oil usage.

Pricy but suppose to be good synthetic oil.

This is a great product,,, exceeded expectations

Great Product and Service!!

Purchased for my tractor

Everything shipped in a fantastic manner and packaging was great

I just finished my two free oil changes with the dealer and just did my third oil change myself with Amsoil. I changed the oil when the dash indicated I had 50% remaining life and will continue to change the oil at 50% remaining life. I believe GM recommends “Dextros” and Amsoil does not have that term on the bottle however, I believe Amsoil exceeds the GM spec and does not need to pay GM to advertise the Dextros name.

Top Quality oil

Awesome oil for my 2021 6.6 Denali 2500HD ! BEEN USING IT FOR 3 YEARS!! VERY GOOD 💯 MY DIESEL LOVES IT AND I DO TOO.

Since using this product my truck smokes less.
