Cm2250 oil pressure numbers???

[Rawze]

15 PSI is the bare minimum required oil pressure at idle from my understanding. Personally, I would like to see it up at 18+ at idle and that is what it is on my CM871.

I do run a gallon of gear lube though too, and that helps it a lot in this regard, especially in hotter weather. It is also why I use a gallon of 85/140 instead of 80/90 in the mid summer months.
