oil pressure fluctuating
hey guys dumb question but my oil pressure is fluctuating.... at 1000 rpm its at 12-15 psi at 3000 rpm its about 40 it goes up with rpms but ive never seen it get that low at idle it use to idle at 20 its a fresh oil change my question is what could be causing the flutuating gauge

Check Sending unit
While it sounds pretty serious, if the motor is still running OK with no unusual noises I'd check the oil pressure with a mechanical gauge. I've had the oil pressure sending unit go bad on three different cars and a diesel truck. Start with the least cost items before spending money on the expensive ones. I'm sure you've already checked the oil level. Since the problem started after the oil change, could the wrong oil or filter have been used? Good Luck.

The sender unit has done this on a few F-bodies I have fixed. Most definately check you actual oil pressure with a wet gauge to be sure.
