Lately, my 300E has developed a strange thing....the Oil Pressure, at idle, is 0.5 bar, but when I rev the engine to above 1000rpm, the oil pressure goes up to 2.5 to 3.0 bar. I've check the oil level and it's at max. I've search the forums and it seems that this is normal? Can someone please confirm?
BTW, the oil pressure was at about 1.0 to 1.5 bar at idle about a month ago, and this is the reason why I am worried.
