What are best practices for idling and what are the theories behind them. For example, I never use my base idle speed unless I'm in traffic or at a red light. Otherwise, I'll high idle (1,000 RPMs) or turn off the ignition (preferred).
Is the high idle at startup to charge the batteries? or is it to get the engine to operating temperatures faster? And does it really matter at all given how little we actually use our engines in a diesel RV?
Idling at low idle isn't hard on your diesel engine - as above. High idle is mainly for charging the batteries when running accessories. Idling while fueling is what I do because I move out of the way of the 18-wheelers so's they can fuel.
