Customer Ratings & Reviews

Great product at a great price. Definitely recommend driving in all kinds of conditions

I’ve been using AMSOIL now for about 20k miles and it’s great. Only problem is that the only filters ever available are the junk Wix filters. I tried it a couple times and am not impressed. The AMSOIL filters are much better but haven’t been in stock the last 3 times I’ve ordered oil. Hopefully the supply issues are resolved soon.

Love the oil, however had a hard time pouring the oil. Container is large and somewhat awkward to pour even with a funnel on the Ford 6.7L engine. Think I’ll stick with the 1 gal jugs.

Keeps the 6.7 running beautifully Good stuff. 200k and climbing

FOR MY OWN TRUCK .

I have used this since 2018. I follow the severe maintenance schedule for my truck due my driving style. It works great and I Love the convenience of having it sent to my house.

Expensive but cheaper than buying a new engine.

Not much I need to say the product itself speaks for itself since I’ve switched to Amsoil I’ve seen a change in the way my engine runs and very impressed how the oil holds out

I’ve been an AMSOIL dealer for years, great products, great service and fast shipping, can’t get much better then that.

I have owned diesel trucks since 2006. Made my first AMSOIL purchase and am now wondering why it took me so long to switch. Excellent product. Super fast shipping. Great price. Oil and filter “kits” ready for my specific make/model. Yes please and thank you!

Great oil and product at a good price. I don’t get the dreaded L5P typewriter tick and I don’t have to add an oil stabilizer any time of the year. Really happy with the product and definitely recommend it to everyone!

AMSOIL is hands down the best oil I’ve ever used. From the quality of the oil, the service company provides, to the random gifts you get sometimes. I constantly recommend AMSOIL!

Very happy no major complaints looking forward to see how amazing this oil truly is

It’s a great oil that’s all I run!

Best oil you get what you pay for.

Quick delivery and fair prices. I plan on keeping my Ram 3500 for ever, so I treated as so.

I'm using this oil since I got my diesel truck, I will not change

Great oil, never had an issue

I've been using Amsoil in my 2009 Dodge 2500 diesel nearly since I bought it. Still running smooth, even though I've let it go way over on changes once or twice.

This is my second oil change and I only wish I had started using it sooner. Previous oil changes and after 100 miles it’s back to its old black color; not with Amsoil! This is the best oil and I highly recommend it!
