Been using in my tractor trailers for over 40 years and over 5 million miles. Never had an oil related failure. There are newer and more expensive oils o in t there, but it’s hard to argue with success…

I've been using Rotella T4 for a long time in my semi truck engine. Newer had any problems. When you change the oil in the engine you can tell that it's Rotella, because it has specific scent no other oil has. Great product.

Who picked the 2.5 gallon container size... obviously they don’t change their own oil. My truck requires 13 quarts... normally 3 gallons and 1 quart. Stupid

Bought the 3 gallon eco pack poured into jugs and only had 2 gallon and 3 quarts if they are all like this I'll not be buying anymore!!!!!!!!!!!

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

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

Waltmart you guys CRAZA today with the price.... $70 for Rotella Oil 2.5 gallons... Some one need to fix this prices

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!

Using for farm use in older Allis Chalmers and IH diesel tractors and it seems to be the right formula for these work horse tractors.
