Friend of mine just bought there first 52 with the Cummings in it. They did a service (fuel,oil, air 15w-40) oil pressure reads 9 to 10 pounds at idle 60 pounds at full throttle is this normal.

Thats on the low side for that 8.3 cummins. Normal is in the 25-30 range. On the other hand it could be a bad gauge. Usually when you are on the low side of the oil pressure you cannot achieve 60lbs at full throttle.

Change the gauge

The engine shuts down under 12 psi if I recall... Have had that happen where the gauge shows fine at high pressures but shows low at lower pressures.
