fair enough I may have engaged in some hyperbole there. But it is still rather unnecessary.

:thumbup:

I read a similar thread about someone's neighbor with a very loud Harley who SWORE he needed to let it warm up a good 15 mins before every ride. Two very different opinions!

We all have that a-hole Harley neighbor. Those are often worse than them ricer kids.

On topic: I do let the engine warm up, especially in winter. Side benefit is warm seats.

I'm willing to wager a few of us ARE that a-hole Harley(or other) neighbor!

Yup!
This thread should be about temp#'s not my neighbor splashes in they pool.
@4 minutes 135*F,@9 minutes 184*F driving 40 mph.Mine won't hit 190 till I'm @55 mph.

The engine is going to warm up whether you do it at idle, or with a moderate load on it

The first has the longest duration warm up cycle, so the most engine wear.

The second has a shorter duration warm up cycle, so less wear.

Drive away, moderately, as soon as the windscreen is defogged, or whatever else takes a few moments. Don't rev it up high until the oil is to temperature, which takes longer than the coolant.

Or don't, and just accept more rapid wear.

What does your owners manual say? All my BMW manuals have always said to start engine, then drive away...not recomending long idle. Examples from my e53 & e38 are shown below.

BMW also designed an engine warmup cycle in conjunction with the no idling recommendation.

Surprised no one had mentioned this yet, but never understood the logic of letting your engine warm up at idle, what about the gearbox and diff?? They will still be cold and you'll only accelerate the wear on those components if you the think the engine is good to rag.

This. I'm not concerned about engine temperature but more throwing the transmission into drive when engine RPMs are still slightly high at start. I grew up in Chicago--I just remember always having to let the cars warm up when cold--maybe I'm scarred for life ha.
