oil pressure

i noticed this about on a bunch of GM cars how come they always have high oil pressure? my buddys monte carlo was this way my friends lumina my truck n ive seen it on a few customers cars at the shop i work at...

not that it is high. its just look high cause the gauge is a smaller gauge. my s10 reads around 40 and is almost to the high point of the gauge. I looked at a audi pressure it was at 40 and the needle was close to the bottom. but the gauge was a bigger gauge then the one I had in my truck

This is new.Most S10 owners bitch that oil pressure seems low.

i agree always seems to be low, never hearing a complaint about it to high

if it works don't question it. To much oil pressure will only hurt if the oil doesn't flow back into the pan fast enough, allowing it to suck dry

the reason oil pressure on chevys always seems so high is because the oil pressure sending units are junk. they get clogged up and at idle they appear to be working fine but as soon as you hit the gas they go off the charts. if you replace the unit ($30.00, and is easy) this should fix your problem until the new one gets clogged somewhere down the line and starts doing the same darn thing again.

its actually not that bad, jus cause im used to my eclipse it is turbo n they run at low pressure at idle almost no pressure it seems so when it sits around 50 or so in my truck it seems strange to me :dunno:

Was told this by a old gm rep. The GM gauges are set up to have the reading needle in the middle of the gauge scale for normal operation. While driving a quick scan will show most gauge readings in the middle so the driver knows all is good
