My oil pressure gauge shows lower readings?
My oil pressure gauge has always been between 40-60. Recently it has a tendency to
drop after driving for several minutes to 5-20 psi. It even has hit zero while driving down
highway. No loud engine noises were heard at these times.
Are you due for an oil change? If so, change it and see what happens. Could be a faulty oil pressure gauge or gauge sending unit as well. HTH. -Jim
