    oil pressure guage

    When I turn my car off, my pressure guage stays at the direct middle or occasionaly it will slowly go all the way down. Also, when I start my car the pressure is high like inbetween the last last 2 ticks. When the car worms up, the pressure goes back to normal. Is this something I should be worried about? Do you think my guage is scewed? Please let me know. Thanks.

    When the car is cold, the oil is more viscous and will record a higher pressure on the gauge. After it warms up, it "thins out" and the pressure will return to normal.

    Thanks...so a change that drastic would be caused just from the viscosity? The pressure also return to normal when I depress the clutch (motor under no load). Should that big of a change be seen? Is it ok to have high oil pressure?

    That's strange my gauge falls flat as soon as I turn the engine off. No pressure no reading, right?

    Yes this is normal and on mine when I'm accelerating my gauge moves up. More RPM's=oil pump spinning faster=higher pressure.

    It sounds like a lazy/slow sensor or maybe something is holding oil pressure like plugged oil passages. My.02

    We talking about the stock gauge? Oil pressure gauge on mine has always stayed at about a 1/4" past 40 after car is turned off - have friends whose cars do the same thing?????

    Staying at the last setting turning the key off is normal - "ocasionally it will slowly go all the way down" isn't. Unless you do something, like turning the key to RUN and not start the car, etc.

    My '02 SS stays at 40 when the car is turned off but when I put the ignition to the on position then back to off position it falls back with the rest of the gauges...but when I put it back to the on position it stays flat and all the rest go into their positions...not sure maybe a bad connection or ground, not sure on how the gauges actually function in that respect. Anyone have any ideas? Gauge functions properly when car is running and driving.

    well from all I have read the guages in the 99-02's are reference only

    they are electronic guages and any fluctuation could be interference from the stereo or alternator or a number of other things

    I wouldn't worry about it
