Re: Follow the MM for Oil Change - Debate goes on
I never understood what is gained by prolonged idling any engine not being used (such as service vehilces ie; diesel).
Some do it to warm up in a very cold environment, then drive off fast totally ignoring the fact the rest of the drive-train needs to warm up also. One or two minutes at idle, and then driving off moderately makes sense in very cold weather. In warmer climates very little idling is needed, if at all.
'Warm-Up' aside, as said, the engine is very inefficient at idle, and excess wear can occur over time.
