? duramax

Yea at a stop light it reads 20-25 lbs. then goes to 50-60 lbs. while driving. Let me know it that is the same on yours.
I double checked. 30 @ idle and 60 while under way.

Thanks.

I think the Duramax has oil spray nozzles that spray underneath the pistons; which gives the oil pressure lots of places to bleed it off. Other engines that utilize this feature tend to have lower idle oil pressure. I run 15-40 Amsoil synthetic marine/diesel oil in mine which gave it a couple more lbs of oil pressure.

Cool thanks I will try that oil.
