Extremely low Oil Pressure...?
Sometimes my oil pressure gauge only reads 17 psi at idle...other times it's 40. It varies...but the car has never knocked or shown any signs of such horrible pressure. Is the stock gauge just screwy or what?

It reads A LOT of different things at cruise speed...normally in the 40s...sometimes 55-60.
Isn't it pretty bad if that's where I'm idling?
BTW, I usually idle in the mid 20s...it's just odd how it changes so often and so drastically.

cruise spec is 45-60psi, and about half of that at idle
the hotter it gets, the lower it will go, and the oil weight will play a factor
going to a higher weight raises it, but this is a stopgap maneuver
I dont think its a big problem.

Engine hot, minimum oil pressure @ 1000 RPM, 6 psi.; @ 2000 RPM, 18 psi.; @ 4000 RPM, 24 psi.
Obviously none of us would want our pressure readings this low, but these are the acceptable GM specs straight from the manual. So Zerski I'd say your numbers are actually in spec. (I guess, this is from a 94 manual I don't actually know what year your car is since you haven't filled out your profile).
