low oil pressure

[smoker]

mine went about half way then dropped back to 1/3 before rebuild, now it goes 3/4 cold and just under 1/2 when really hot. Think it was just general wear in crank shells and leaking turbo seals but never made any knocking noises.
I would think that a 10w-50 oil would be better at maintaining hot oil pressure than 10w-40

yeah but 10/40 is cheaper and she leaks from the turbo return, and turbo seals r a bit on the shite side
