Oil pressure on the new caddy.

[chevync]

Took my daughter to a Christmas light show, toward the end I noticed the oil pressure gauge was slowly going down, engine runs great no weird sounds, hit the interstate it's still reading between 8-15, stopped at the store shut it down for a few minutes, it resets and back to normal, did great for 5 miles or so, then did the same thing again. Got home, runs perfect no weird sounds, waiting a few minutes and fired her up, back to normal. Could it be the sending unit or gauge?

My guess is the gauge. NBS gauges have known problems. Had a duramax that did the same thing. New cluster fixed the issue.

The oil level is good?

All you can do for now is watch it.

Yeah, i'm hoping it's just the stepper motor, if it was oil pressure it wouldnt have went back to normal on start up and stayed there for 15 miles.
