OK, here goes, I have searched and searched, but not found an answer. My oil pressure gauge seems wonky. At idle, it does not read any oil pressure, but at highway speeds(65ish) it is rock solid in the middle of the gauge. I know that the gauge reading will flucuate with both rpm, engine speed and temp(of the engine). The dipstick reads full all the time, I have been checking the oil every day due to the wonky readings. Here is the gauge today as I was driving to work on surface streets.
