Denali n DOO
- May 22, 2012
Hi all. I was driving home from cottage yesterday in stop n go traffic for quite some time. I was noticing that when cruising oil pressure is one tick to the right past center. When I stopped the oil pressure drops three ticks to the left, step on gas and up it goes, stop again and back down. This only happens when engine is warmed up. First drive today when cold and the gauge stays in the middle, after it warmed up it's drops again when under 1000 rpm's. Oil changed last week and it did this before the oil change too. Any ideas as to what would cause this? I wonder if the gauge I'd just messing up, I have a launch scan tool not sure if it reads oil pressure?
