Great purchase and value if you have a diesel especially a Cummins. First oil change was done with Shell Rotella T6, which gave me no issues. But I don't drive my truck a lot so occasionally after sitting it would be a lil noisy on startup. With this oil my trick can sit for a month and have zero noise on startup which is great if you know anything about the noise some of these Cummins make or diesels in general. Performs great as I have no oil loss when conducting visual and mechanical checks of my truck. Like all oil changes it's pretty straight forward and easy to utilize. Definitely will purchase again when needed.

It's all I use

Only place I can find the correct oil for a next gen Cummins !

Came on time and was exactly what I ordered!

I gave 5 stars for value for money, but that's because I bought the 3 pack before the price went up. I wouldn't buy it now that the price increased. It's good oil, but the Chevron Delo I had in my VW 4 banger before this oil lasted longer. This may have been because I had some Mystery Oil mixed in ? At any rate I'm using this stuff up but won't buy again there's better out there for this price point. Got a deal on Shell Rotella full synthetic Diesel oil, I'll try that next and see how it stacks up.

Nice product

This is what Cummins tells us owners to use. The 3 Gallon pack is the perfect amount for an oil change.
