Low oil pressure when cold.

Question

2006 1500 4wd avalanche with 200K miles, has low oil presure when cold. I was told there was a service bulletin out to replace one of the mian bearings and that would fix it.

Answer 1

what weight of oil are you using? and how cold are you talking about?

a lot of people switch to 0w-30 oil in the winter time. I would recommond pennzoil ultra or platinum
