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

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 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!

I use this oil in several vehicles, especially my older ones. It has more zinc than the newer oils which is needed for flat tappet engines. You also can't beat the price if you use a lot of oil.

the best i could fine

I have over 150 thousand miles on my 5.9 Cummins. with nothing but Rotella for my engine oil. Great protection

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

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 been using shell rotella since i bought my first 18Wheeler,i have never been down due to oil issues,"rotella is my brand !!"
