70k on the new DI engines?

Kinda nature of the beast for now. Besides you are supposed to trade them in at 99,999.9 before they fall apart and just have car payments forever and ever so we can keep the air clean and save trees and crap like that. So if we keep em traded in we have clean air and the next poor SOB who buys it after that has to worry bout the problem.

Extended oil change intervals, 0w oil and weak PCV systems don't help this at all. 3K oil drops and a good air oil separator would reduce this.

mini specs either 10 or 15K intervals on oil changes, but run a standared 5w30 oil or something like that.
I really like the new trucks but for the price they are asking, i should be able to go 200k miles with out worriing about **** like this.
my old 99 is well over 200k and still going strong. my dads quadrasteer sierra denali is over 300 now with no issues.

I agree with RacinRust here, 3-4k oil changes and a catch can are cheap insurance. I will add that the pcv system on these Gen5 v8s is supposed to be a vastly improved to combat this issue, but time will tell I suppose.
