My oil pressure gauge on my '02 Tahoe 5.3 just sits at about 40-42 psi at idle and even at 70mph. It moves so ever slightly but remains in that general area. Usually it is at about 45psi at idle and about 70-80 at 70mph.
It returns to zero when engine is off and key is on. It will go up to 60psi when first started but then goes to the 40-42psi and stays there even if you rev up the engine.
Engine seems to be running as good as it ever does.
Could this be a gauge issue?
Thanks
