Mounted a new (or maybe just different?) engine in BDL. It flew to ORD where I got it. Flew (with no autopilot) from ORD-SAV. About half way we noticed the oil pressure was in the green, but bouncing all over the place. Ran QRH, no change. Conferred with the company, they said press on.
Land in SAV, contract MX comes out and puts a reasonable amount of oil in it, still shows empty. No evidence of leaks, so they put a fornication ton more in until it's topped off. Quick engine run and then it was off to ORD.
I guess it's shipped with a certain amount still in it, engine DGAF and ran anyway.
