I just pulled my camaro out of the garage after a long cold winter. I started her up, and drove around for a while. I noticed after the car got up to operating temp, my oil pressure was running lower than normal. When I parked it it would run at 40 PSI hot at idle. Now it running about 25-30 PSI at idle hot. the engine doesn't sound any different, and when you get on it the the pressure goes up past 60 PSI. The guage sensor messed up, or could it be something much worse?

I pulled the dipstick and it is that dark reddish color. I am going to change the oil this weekend, and will see what happens.

this is whay you are suppose to change the oil after a car has sat for quite awhile. Could also be the sending unit going bad.

Changed the oil and filter today with mobile 1 0W-40 and an ac delco filter. Oil pressure is now at about 40 PSI or about a **** hair less at idle. Wrap it up to 2K rpms and the pressure is about 50PSI, and giving it a rev to about 4K is over 60PSI.

When I changed the oil there was some gray sludge like stuff on the plug magnet, but no big chunks of anything. The one thing I did notice was the pressure gauge needle fluctuates a bit at idle. Hopefully the pressure is good enough?
