High Oil Pressure
I just changed my oil earlier today from my synthetic blend to full synthetic Mobil 1. My oil pressure has not dropped below 2 bars since i changed it. Is this usual and will it go away, or is it normal for this increase to occur with a fully synthetic oil.
TIA

My car has used fully synthetic oil from new. My oil pressure never drops below 2 bar. In fact it normally stays at 3.
I think it's because synthetic oil is better at high temperatures than regular oil.
It's a good thing, not something to be worried about.

Echo Cap'n Jasper. High pressure = Good. 2 bars is about 29 PSI. There's nothing wrong with that. Also, cold weather will keep it higher. The thinner the oil gets, the lower the pressure at idle. Thick oil means higher pressure because it doesn't squeeze out of the main bearings as fast.
