My Trooper has an oil pressure gauge fitted, around town it stays around
2kg/cm at idle & 4 at double idle. On a long run at 70-80mph it goes down to about 2.2 at 3 times idle & 1.8 at idle (if I stop etc) is this an effect of the oil getting hotter & thinner due to the run etc or is it likely to be something else. The machine runs sweet as a nut with no oil use I can see. I ask in this group as the Isuzu group is crap!Idle speed is 800rpm if it matters.
