Base Idle, Fast Idle, Non Idle - Best Practices Diesel

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) ...

Holstein13, it was emphasized that we keep our engine at high idle if the engine is running and in 'Park'. We have a switch on the dash with a rabbit on it (high idle). I engage the switch after I start the engine after about a minute or so.

The purpose is so that the engine is sufficiently lubed including the turbo.

Our previous coach had the high idle switch on the smart wheel. Our smart wheel has the cruise on the left and the engine retarder on/off, high/low switch on the right side.
