Oil pressure gauge jumps around?
While driving and at idle it jumps around alot. It's will go from 20psi -40 and back and sometimes will go all the way to the top and sometimes with sit at 0 psi while driving for a bit. It's been doing this for about 4 weeks now. Would a little coolant in the oil cause this. Cause I know its leaking a bit into the oil. It's a 350 chevy with 200,000 on it. The sensor is only about 5 months old

Still could be a faulty sensor or the gauge is going south. Check the condition plug going to the sensor

If it's an electric gauge, bad connection or fractured wire at the oil pressure sensor on the engine.
Could also be loose instrument fuse or other bad connection on the power side.

Check the pressure sender. You'd know if you truly had fluctuations like that; which could likely be traced to a massive leak that seals itself randomly
