i don't even think about the low oil pressure anymore because the stuff they are doing with these trucks now will mess up any traditional thinker. I got tired of feeling stupid every time i called the dealer because something was not like it would of been back a few years ago.

have not called about this one though. but in theory 10 psi per 1k rpm is ok.

I was twisting the dealers arm to special order me a vmax reg cab, but the guy said they won't build it, so I settled for the lil 5.3...

They need to just get rid of the 4.3 and make the 5.3 the base motor. with a 6.2 option.
