I have been using Shell Rotella 15w-40 for my diesels for about 10 years now, and I am very satisfied with the performance of this oil. I have had no problems with it at all!

My wife and I are boaters and each fall we change the oil in our Diesel engines and the generator. Each year we need 10 gallons and purchasing 4 of these and having the delivered to the store made it very easy for us. Thanks Walmart

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.

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…

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

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

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.

For months i have trying to get 55 gallon drums of rotella motor oil talked to carol many times did not call back

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