ever since i got my car my oil pressure gauge has been fluctuating a little between changes in throttle pressure. is this normal or is something wrong with the gauge, cuz the car performs fine. thanks.

Oil pressure sending unit or bad pump. Leaning more on oild pressure sending unit.... check ur oil level

mine flucuates when i am at idle and changes under throttle, so does my gf's TA

pretty sure its normal

Oil pressure should increase with throttle, if that's what you mean.

As long as it doesn't go to low, you are fine.

idle mine is at 35-40 then on throttle it goes to 60 as well as my gfs, sure they arent your car but this should help ya out

from what i know its normal for the guage to go up when your on the gas and down when your not.

mine idles at 20 and under throttle it goes to 40. cold starts will show higher pressure until the oil is warmed up.

Mine Idles at 10, can we say boom boom soon?

youre gonna hear someone "knocking" at your door soon.

mine is: cold start idle- 50-60psi, hot idle- 20-22psi, driving hot- 40psi

Whats wierd though is that in the owners manual GM say that normal psi at idle is 6psi

Mine has been idling warm around 10-12psi, cruising around 40psi, and WOT around 55-60psi for about 30,000 miles now.

Thats about right...

MIne bounces everywherea taidel though... i need a new sending unit (that is why i got my autometer gauge...)

cold start mine is at 70-75 psi, warm normal cruising is 50, wot is 60, idle is 40 after heating up

The oil pump runs off the motor, which obviously will spin faster with more RPM. Faster = higher pressure.

The stock gauge is pretty inaccurate as well, most of these guys with low pressures probably aren't really running that (or the higher pressures either probably). If you suspect your pressure is low first thing I'd do is get a mechanical gauge and verify the actual pressure.

My dash gauge reads around 18 psi at a full warm idle, and hits about 30 at cruising rpms and 38-40 at full throttle, all at engine fully warmed temperatures. According to my mechanical gauge I've hooked up to verify readings, my dash gauge is about 8-10 psi low across the board.

GM's specs are actually really low, min idle of 6, like 18 at 2000 rpms and 24 at 4000 or something like that if memory serves, I'd be more than a little worried about my engine if it only held 6 psi at idle though...

They say an engine needs about 10PSI per 1000RPM dont they?

ras928

i think its 5psi per 1k

thats about where mine is and its a new standard mellin pump.
