Customer Ratings & Reviews

I use this oil in my 2021 DD16 Detroit Diesel in my Semi and my 2015 6.7 Powerstroke. It does a superb job in my Semi under very hard conditions so it was a great choice for my Pickup. The engine Manufacturers for both Engines recommend a good Quality 10W-30 oil. I love this Oil in both of my Trucks and will be a AMSOIL Customer for Life!

I've seen my mileage go up and I feel comfortable that my High Output 6.7L F350 has the best protection I can give it. I let the truck tell me when to change the oil and it has been going 10-11K miles between changes. Won't put anything else in it.

Fast shipping and best lubricants money can buy. Everything they make is the best.

Amsoil!

I use Amsoil for my 2013 6.7L Ram I can travel further with the synthetic, now it’s not cheaply priced but I don’t have a problem with it because the oil is very good. I will be purchasing again.

I need a hard working oil in my truck that I use to haul a 5th wheel. This oil offers great protection.

My 2019 2500 hd Silverado uses only Amsoil

Best oil quality in market. HTHS is 3.5, minimum required by Ford. It is OK. Recommend everyone.

So far so good, I've heard a lot of good stuff about your oil. I hope it's better than the free Tire Gauge that I received with the oil.

Great stuff

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!
