Engine Mechanical problem
2001 Pontiac Bonneville 6 cyl Front Wheel Drive Automatic 99,000 miles
I recently changed the oil and filter on my car. I used the same size filter and put 5 qts of oil back in it. I started the car and checked the oil pressure gauge and was shocked to see it reading 120psi. The engine seems to be running fine and the filter has not popped off. Could it be that the sensor is faulty? I checked to make sure there was not to much oil in the engine as well, dip stick reads just below full.
