Wouldn’t wanna run anything else in my truck, others oils don’t last and make the truck run a little funky. 1996 7.3

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

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!

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.

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

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

I use it in all my small engines sae30 and t4 in my powersports. Never lets me down

A solid performer for my diesel truck. I use it all the time
