my oil pressure stays at 40 but when pressing on the gas it floats up and down on the gage. Is this bad??? just put a tune up in it not a month ago.
It's a 2 wheel drive, c1500 suburban. It has done this since I bought it a little over a year ago! Hoping its Nothing but willing to get my nails dirty if it is.
No its not a bad thing, i have a 2006 gmc sierra and it does the same thing. For some reason gmc and chevy trucks oil pressure gauge moves will accelerating. The pressure itself doesnt change just the gauge.
actually all my gauges do this but the oil has been worring me the most. thanks for the info Brett it is really appreciated
This is supposed to happen; higher RPM=higher oil volume oil pump moves. Mine idles around 45 and will peg the gauge at 80 psi when it gets cold up here. done it for 200,000 miles. i'd be more concerned if nothing happened when accelerating.
The oil gauge on my 2000 chevy silverado keeps going higher then 45 when i idle up and when i slow down it goes but to normal
