High oil pressure on 912 ULS

    5 bar at idle and WOT sure sounds like a sender issue.
    I would be very surprised to find that it is real.

    Once again, the Mechanical Gauge will tell the story.

    Hi Bill,

    I see a lot of oil pressures at 60-70 psi right at start. My FD CTSW did exactly that. Then as it warms up those people settle down to 42 - 58 psi with an average of 50 psi.. That isn't high. From what I have seen most oil pressures are not spot on accurate. They can be 2-10 psi off depending on the oil pressure sender condition. A poor ground can cause pressure difference. 4 bar or 58 psi isn't high if it is real.

    Easy numbers for those that aren't sure.
    For those that aren't sure what a bar is equal to.
    1 bar = 14.5 psi

    When you hear the airfield tower give Celsius and you want to know Fahrenheit.
    A quick and easy way to convert Celsius to Fahrenheit.

    Double the Celsius, then subtract 10% of that answer and then add 32F = Fahrenheit.
    Example:
    20c x 2=40, subtract 10% which is 4 from 40 = 36 and then add 32 which = 68F 20 c equals 68F

    30c x 2 = 60 - 6 = 54 + 32 = 86F 30c equals 86F

    5c x 2 = 10 - 1 =9 + 32 = 41F 5c equals 41F

    My question is not how to fix it but is it safe to fly with a reading in the low-mid yellow range.  Fly, as in get it to a mechanic.
