Re: Normal Oil Pressure
I have two data points for you:
1) My father's '82 Coupe. Reads a fluctuating 1.5 - 2 bar at idle when hot,
goes to 5 bar when revved.
2) My '85 Coupe GT. Reads a fluctuating 2.5 - 3 bar at idle when really hot,
3.5 - 4.5 bar when at nominal operating temp, and pegs the gauge when
revving. When really pushing it (full throttle, up to 5K rpm or ss), it
often will drop down to 3 bar or so (which makes sense).
BTW, I'm running Mobil-1 15W50 and my father is using Castol 40W.
Realize that new oil will hold a higher pressure than older oil, and straight
weight oil will hold a higher pressure than dual-weight.
I think your guage may be working fine, but reading higher pressure than
the oil is actually at.
