Shipped promptly, and is a great product. Unpaid spokes person.

This is the best diesel oil to use in your diesel engine....my cummins works & sounds smoother

Great product!

Works great

I’ve purchased these products for my motorcycle and diesel truck. Love it. From oil to fuel additive and gear oils. Great Product

Great product but the price is becoming ridiculous. I will probably be looking for an alternative soon.

Excellent diesel oil with max protection

Difference is unbelievably a huge upgrade in performance and protection, engine is running smoother and starts easier especially where I live it’s been 12 degrees at night even though I use my block heater I’ve noticed a huge difference in starting, before Amsoil I used only rotella t-6 full synthetic and I’ve always changed my oil every 5,000 miles, I’m a preventive maintenance person and I’ve noticed my last few oil changes the oil was really thin and it just didn’t sit well with me. I only drive about 10, 000 miles a year so it will be nice to only change it once a year.

I’ve used AMSOIL products on all our vehicles since new and have never had any issues. Would recommend to anyone

after Break-in period of a rebuilt Manufactured 6.7L started using Max-Duty and can tell it's a high-quality oil, by sound, etc.

I ise amsoil. My truck is still running. It must be working ok.

Best oil money can buy!!

I cant say enough about this oil. Its the best you can get.

The product speaks for itself, however being able to order it and have it on my door step within a few days at no additional cost is amazing!!

Oil is the best available that's why I use it.

Fist time buyer, so far no complaints

Great product, I use it in all my deisel trucks (4) and also in my older tractors (6). It last at least a year in most of my trucks, before I change it

I trust this product in my 2007 chevy 2500hd LMM duramax.

You already know!

I just changed out 5W-40 for the 15W-40 recommended for the Chevy Duramax 2500. Perhaps I should have stayed with the 5W-40 for the colder weather. Somewhat unrelated but when I bought the truck two years ago, I had bad torque converter slap. So much so I thought there was something wrong with the engine mounts. I changed transmission fluid to AMSOIL and have not experienced the torque converter slap at all. Amsoil products are excellent.
