Cummins ISC oil pressure at idle
The motorhome I'm ready to pull the trigger on has a Cummins ISC engine and It only has 10 lbs of oil pressure at idle. Is this normal? It seems awfully low. The engine has 25000 miles on it.

With our ISC when oil temp is normal my pressure is 24 psi at idle, according to my Silverleaf monitor.
