I bought this a month ago great purchase and value.

Better price than the bulk dealer on T4

This my second drum purchase. Use it in all my diesel vehicles.

Good product, we only use this oil.

Purchased for my trucking business very affordable and practical!

its oil!

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!

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

I've used Rotella T4 15-40 in my 1300cc liquid cooled motorcycle for years because of its heat hadling capabilities and wear resistance. Very pleased with the results and does not compromise the clutch action.

An excellent product for the gear box of your off-road motorcycle. You get a gallon for the price of a quart of boutique oils. I have run Rotella for 15 years and never a problem. I get long clutch and bearing life.
