ok! So the oil pressure once again where is at is perfeclty correct??
two more questions dan...
my last concerned Once i start the engine the pressure always going to be on 60psi and once it warm up it has to be in 42 psi or a little bet below...
what type of engine oil should I use for my duramax??
ok!! so far The oil pressure doesn't have anything to do with the EGR system right??
I put 10W-30 on my engine is tha ok??
and I should change the oil when the truck has how man mileage??
Ya that should be fine but I would stick with the recommended oil.
