I don't care what breaks a rebuild will still cost me $7k!
I think you 617 guys could get away for $5k or a little less.
I will never run mine that low on oil, besides something major would have to blow like an oil cooler line to dump enough oil to hurt anything. I think I would smell the oil burning and see the lights go off on the dash and be able to stop it and shut down before I lost oil pressure.
My oil cooler lines are new so I am not worried one bit.
