Quick question, especially for those with the Z51 oil cooler or aftermarket cooler.
How long does it take your guage to register oil pressure upon cold (sitting overnight) start up? I've noticed mine does it typical full sweep and then registers 5 psi or so and ramping up to 40 all within about 3-5 seconds. Curious if this is the Z51 oil cooler filling up and if this is something to worry about. 2008 C6.
Mine does the full sweep then immediately goes to 40+ psi. ('07 w/Z51). I don't think that the oil cooler would empty since both the inlet and outlet are right at the oil filter.
