yeah, big engines like that are designed to -run-.  locomotives are
usually left idling when not in service b/c of starting issues like
yours.

i had a tour of a phone plant years ago.  phone switchgear normally
runs off -48vdc, with enough battery for 4h w/o external power, but if
that wasn't enough this office had an emd 20-645e [that's 20 cyls, 645
cubes each, 3600hp@900rpm] in the basement as its standby generator.
it had a 15hp electric motor pumping oil and maintaining oil pressure
all the time.  iirc it had heaters too.  they said it could go from
dead stop to full power in less than 5min.  at that time they'd never
used it.
