I am hoping to get a good idea of what pre emission duramax owners are running.
I have found a healthy stash of the LE flavor in 5 gallon pales and 55 gallon drums.
I also found a 55 gallon drum of the LE predecessor, Delo 15w40 multigrade. This is the CI rating.
Can someone with extensive oil knowledge tell me which of the two mentioned would be better for my LB7 duramax?
Truck currently sits at 181 on the clock and is used for towing.
Appreciate any and all input.

Delo 15-40 SDE synthetic blend. Outstanding oil samples and significantly reduced consumption with this oil in my C15 cat engines. Similar results with my duramax as well. Going 20k in the C15's and 12k on the duramax with plenty of life left in the oil according to Blackstone. They say I can go 25k and 12k, respectively if I wanted.
