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

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

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

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

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