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

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

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

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.

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!

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.

One of the two were leaking when i opened the box

Good for your marine diesel engine

oil is good but was listed as 2 packs-received only one-walmart listed quanity wrong-returning

shipped wrong oil 2x, finally resolved by customer service everything ended up OK
