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

This Rotella T 15w40 came highly recommended from a Pro Diesel Mechanic so that's why I bought it. And I would also recommend it for a Diesel vehicle

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

Put stuff in your shopping cart from time to time as you think about it and then at the end of the week have it all sent out

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

This is the number one oil made for diesel trucks. You can't get any better without going to synthetic oils at 3 to mes the cost

I use it in all my small engines sae30 and t4 in my powersports. Never lets me down

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

rigs run smoother oil change last longer.
