I have over 150 thousand miles on my 5.9 Cummins. with nothing but Rotella for my engine oil. Great protection

I've been using shell rotella since i bought my first 18Wheeler,i have never been down due to oil issues,"rotella is my brand !!"

Even in gasoline engines, this stuff is great! The zinc conditions the aluminum head and the cleaning agents are great in high mileage engines too!

I've used RotellaT4 in my 2002Chevy 2500HD Duramax from the first oil change and every 5000 ml. sense.

The only oil I use in my diesel truck and tractor.

Needed the oil and appreciated the price and free shipping.

I use 27 quarts to change the oil in my motor home and has never let me down. Great product

Use this product in our diesel trucks it’s a great oil and at a great price

Ever since purchasing my truck only oil I will use in my diesel.

ROTELLA is everywhere. I see it, I use it, it doesn't let me down.
