oil pressure

Hi guys and girls.

A quick question re oil pressure..Had low pressure showing on the centre gauge b4 oil change, then immediately after change the gauge showed 'full' 5 bar pressure. A few miles up the road and its now gone back to showing about 1 bar !! Is this ok or what should it show ?

all answers apreciated.ta.

Perfectly normal, as oil temp rises the oil thins and so the pump can't pump it as much or as hard so pressure drops.

I would do the normal oil pressure check:

Should be reading 2bar when the engine is at 2000rpm, and the oil is at 80 degrees.

Dont; forget though that the gauge sender could be faulty showing a low reading.

thanks guys, mind's at rest now.
have a good wknd..
