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.

should be 15 and above, but it could be the gauge or sending unit. There is a lot of info about the sending units being bad.
