    The manufacturer considers 1 kg/cm^2 or 98 kPa or 14 PSI normal oil pressure at 800 rpm.

    At 5000 rpm normal pressure is 3.0 kg/cm^2 or 294 kPa or 43 PSI.

    These numbers are MINIMUM acceptable pressure; readings can and will be higher.

    Definitely expect higher pressures at cold startup.

    I don't use a gauge but have seen 2.0L motors exceed 100 PSI on startup, and exceed 75 PSI during normal use.

    My gauge reads up to 100psi and it is maxed for about 10 minutes when I first start the car. When I tested it with a manual gauge it was 125-130psi cold.. of course that's not stock, but I don't think it's far off from what a stock engine would run.

    Since these gauges are not cheap and neither are motors, I'd ask the gauge manufacturer.

    I think the Autometer gauge would be fine, but it wouldn't hurt to call and ask them.
