Hi all,

I have an M6 2LT. I am experiencing the same issue. So, I took it to the dealer. According to GM, this is NOT an issue. They published the following on their troubleshooting site for GM mechanics (I assume that is what it is).

The doc ID is referred to as #PIP4690:

/quote
Condition/Concern:
Some owners may comment that the oil pressure gauge is indicating that the engine appears to be operating with very high oil pressure.

Recommendation:
Under various engine operating conditions 60 psi (413 kpa) of oil pressure may be displayed on the oil pressure gauge. This should be considered as normal operation. In addition, during a cold engine startup (especially during cold ambient temperatures) the oil pressure gauge may display at 70 psi (482 kpa) or all the way to the right. This condition should also be considered as normal operation. As the engine and oil warm up, the gauge should return to around 60 psi (413 kpa).

/end quote

So, it appears the engine is suppose to run around 60 psi. Seems a bad design decision to place 30 psi as the center line. However, I guess everything is fine.
