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 !!"

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

I've used T4 in all my diesel construction for over 20 years. Never a failure to stand -up to the demands we put on it.

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

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

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

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

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

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