2006 Cummins 5.9 - 150k miles.

I know nothing about this 5.9 that I just bought, except it really runs good.

I've always used Delo 400 in diesel engines, what do you prefer and why?

Thanks

I use Shell Rotella. But, my understanding Delo works, also.

I use whatever is on sale, but mostly Valvoline blue. The important part is that you maintain the truck, not which brand of oil you use. IMO

For the engines that DON'T require the newer "LE" low emissions formula AMZ/OIL still makes their 15-40 Diesel Marine oil.

I would run that 10k in my 98 12V with Blackstone report saying to try 13k next time. I changed every 10k just because it was easy to remember and i bought 55 gallon drum at a time.

^Does the regular dino Rotella still smell?
I don't typically run that because it used to smell like you had an oil leak on the exhaust.
Have t tried it in a long time, but run T6 in the wet clutch bikes and SRT

I run Shell Rotella T-6 in my 5.9 because it is a superior oil and right now they have a discount/rebate going on.

I use Delo 400 in my 5.9, buy it on special at Costco. However, I change my oil at smaller intervals than most as the process is simple and relatively inexpensive. I may be wrong, but in my mind, clean dino oil may be better for my engine than dirty synthetic oil. If I had a bypass filter, I would run synthetic with longer intervals. Since my truck has low miles, I can't say anything quantitatively about longevity.

I run Rotella T6 year round because I need it in the winter where I live. If you're in a warm climate the standard stuff should work fine and it would save a little bit of money. T6 is pretty cheap on Amazon, though, and I think there's a rebate right now.

Durb - I agree with you, I rather have clean oil than older high mileage oil.

In the 2001 ran Delo 400 Dino oil, 10,000 mile changes, safe per BlackStone TBN testing. Could have gone more miles, 10K was about a year, so good timing. Fleetgaurd filters.
Replaced tappet cover gasket at 298,748 absolutely clean inside.
