The oil pressure gauge falls into
the everything-else group of gauges - please check the gauges primer for more
info. Oil pressure would normally run between 20psi and 70psi with the
stock oil pressure regulator. Oil pressure can also fluctuate a bit
depending on oil weight, so keep that in mind if you're changing oil
weights. High oil pressures are not necessarily that bad, but low oil
pressures is danger. At 4kRPM, you should see at least 50psi of oil
pressure - any lower means something is wrong.
