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?
IMHO - the high idle is just that a high idle - allows you to idle at 1,000 rpm's without having to sit in the seat and put your FOOT on the pedal.
The new engine has a computer that is much smarter than you or I - it is designed to allow these engines to run better and longer - don't try to over think it, just drive it and enjoy it. These same engines are used in all sorts of commercial applications with NO REGARD for the engine, or it's life. I've known commercial engines to "survive" for 10,000 hours of run-time on one oil change - not that it did it any good but after 10,000 hours of run time it still had oil pressure and still preformed like all normal diesels, doing it's job.
My Guess is that when you and I are gone, both of our engines (DIESELS) will still have a lot more life in them.
Relax and enjoy the Coach,
JMHO,
Unfortunately, my computer won't engage the high idle automatically, nor will it turn off the ignition. My engine purrs at base idle until I actively force it to high idle or turn off the ignition. My computer may be smarter than me, but it won't manage the idle speed without my input.
But maybe it doesn't even matter. As you wrote, these engines will take abuse and last a very long time almost no matter what we do to them.
