Customer Ratings & Reviews

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!

I use this for my 2025 Ram 2500 Cummins 6.7. It’s a great product for a reasonable price. I have my oil tested. I change my oil every 15,000 miles even though my test results say I can run it even longer.

I researched your product and it was advertised as highly rated and high quality oil and filter. My oil was changed with your kit and then my GM developed a typewriter noise/ticking noise. I took my truck to GM and they advised me I needed to use the OEM filter and oil due to AMSOIL doesn’t airate properly causing bubbling/popping noise in the pan. Once GM changed my oil and filter the noise is gone. I’m disappointed I purchased what I thought was high quality for it to create an issue, so now I’m out double, because my oil had to be changed again.

I have used Amsoil religiously for over 6 years, between multiple vehicles. Most of those vehicles reaching over 200k and 100k miles. This oil specifically I have used between two trucks and it has been flawless! I will forever use Amsoil in all my vehicles.

Works great

I've been using amsoil for 30 years and haven't blown up a motor in all this time. Great company. Capt.Ray

Excellent product. Fast shipping.

I’ve been satisfied with the results of your product the only problem was the last order I ordered from you I only received partial order it was a gallon short i hope this is not a reoccurring issue with future orders.

Put in my metric bike. Engine is running better than ever. Highly recommend!

I order the oil and it shows up on my doorstep. So easy!
