Oil Pressure Gauge Bouncing Around
2003 GMC 2500HD. Noticed oil pressure gauge fluctuates with increase/decrease in RPM's. Normal?? Thanks ya'll.

The pressure should go up a bit as the engine speed increases.
It should not go down much as engine speed decreases though.
As the engine ages, however, the low pressure at idle will get lower and lower as the engine parts wear.
Plugged oil lines can make the pressure go unusually high and the flow unacceptably low.
A mechanic familiar with that engine could tell you quickly.
