Re: Scout 392 Oil capacity?
6-7 quarts is typical on a Light Line install, but a Loadstar deep front sump could be higher.
Most of us actually run ~1qt more than you'd expect to deal with some of the oil drainback issues at sustained high RPM operation on a high-mile 392.
I also run the 1qt high after wiping out #7 rod bearing after running 6qts and racing it for 18 months at 5000rpm+ sustained..
