Id change the OIL pressure sending unit on the back of the block. it is a common problem with these trucks.
However YEAR, MAKE, MODEL, would help to better ID any other potential problems. Also motor size and tranny to.Mike

I had this happen on my 94 Ck1500 5.7 350. It would fluctuate alot and I started to hear an engine knock, well i took it to a mechanic and he did an oil change and used lucas oil stablilzer, fixed the oil pressure and engine knock, 3 months later happened again did an oil change and good as new so that could be an option if you have other issues along with the oil pressure going all over the placeWill From Alaska

Gauges in newer vehicles are electronic, not mechanical. A lot of things can make that happen, none of which may be any indication that the oil pressure is actually low. It could be simply a bad ground connection. If the engine were doing something that bad at 26,000 miles, you would hear noise.1994 Chevy K2500 Silverado, 454 (modified), original owner.
