I’ve have 2017 6.7 with 109,600 miles on it. CP4 grenaded and in the process skipped the crank gear. Front cover was removed to retime which give me a chance to look inside the engine. It was clean as hell with no sludge buildup at all. All that’s been used is Amsoil 5-40 oil. I swear by this product.

Use it in my 2001 dodge ram 2500 24v 5.9 cummins. Works great. I recommend getting the preferred costumer account upgrade, it makes it a fair bit cheaper

there isn't an oil better .

Best oil…. Period!

Excellent and trusted high performance products, definitely recommend. Huge savings and phenomenal performance outta my truck

Awesome product, awesome service!

Works like every other amsoil oil iv used

I’ve been using this product for many years. Coupled with AMSOIL by pass you can’t go wrong.

Best product on the market, I use AMSOIL for all my trucks and never had any problem, I have around 545000 miles on my older truck and engine still running like a champ

Run this product in everything I own. Duramax cummins deere kioti mack all on extended drain intervals with awesome results.

Excelent

Wow, very impressed! I’ve never heard my truck idle so smooth and quiet; I used to run Rotella T6 with Archoil AR9100 friction modifier. Don’t get me wrong, it was a good combo. But the AMSOIL is that much better. And if you add up the cost, it’s actually cheaper and it gets dropped on my door step. I also changed over too AMSOIL ATF and diff oil. I have noticed a slight MPG gain of around 1.5 mpg. I’m going to run double OEM mileage and see as far as long term. But as of now, my truck runs soooo smooth.

I have been using AMSOIL in all my diesel trucks for years now. My oldest is a 2002 Duramax that now has 378K miles on the original engine.

I have always used Amsoil since I was younger and running hard muscle cars on street and quarter mile...now I use Amsoil in my Diesel pulling stock trailers, at ranch for welders and pumps...I would definitely recommend this product to everyone

I’ve always used this brand on anything I have with a motor and I wanted a long life out of my diesel with the right lubricants for internal parts. So why cheap out when it matters the most

great product, amsoil is just amazing stuff, buy it!!

I might go back to the 15w40 for summer. 2004.5 Cummins 5.9 H.O. I have used Amsoil in the engine for 15 years. Low oil residue results. Almost no evaporation. Filters are Amsoil, Wix, or Mobil One. I never exceed 10000 miles between changes. Oil levels are always normal. Early on I used to use Royal Purple. At 10000 miles i would be 1 quart down.

Recently I had my vehicle serviced at our local dealership. The mechanics had to replace the upper and lower oil pan gaskets on my 6.7 Superduty with 120K miles. The mechanics wanted to meet me to express their surprise on the internal cleanliness of my engine.

Definitely the best oil you can buy, makes my diesel run so smooth and quiet.

Very good quality oil and a very good price!
