When you first turn the ignition switch to the "ON" position (where all the accessories and lights come on), the oil pressure should peg high.

Then when you start the engine the oil pressure should come down to about 4-4.5 bar at idle.

As the engine oil warms up and the oil thins out the pressure will steadily drop until it get to about 2-3 bar at idle (normal operating temperature).

If it is consistently running high, expecially after the engine is completely warmed up, there may be a problem with the oil pressure sending unit. However, it could be a loose or corroded connection at the sensor. Try cleaning the connections first and see if that helps.

If the oil pressure runs well below two bar at normal operating temperature, it may be indicative of worn bearings, a problem with the oil pressure relief valve, or a problem with the oil pump. If pressure falls below 1 bar, you shouldn't run the engine until you determine the cause of the low oil pressure.

Sorry about the length of the post.
