We have a Mach-E. I punch that thing the second it will clear the garage door. Holy buckets, what a ride!

Regarding the Harley's, the theory is before riding you are supposed to let the motor idle until the third fin from the top of each head is warm to the touch. I have owned Harley's for 25+ years. I have never let the engine idle. I just take it easy until the motor gets warm. I have yet to experience a problem. I do the same with my diesel motorhome and my F350 diesel. I like to think I'm worried about the environment and courteous to the neighbors but in reality I'm just too cheap.

It's depends on temp and how my fist 5 minutes of driving will be. If it's cold under 40 degrees and I have electric I will preheat the block with the block heater. Or if my first 5 minutes will be higher then normal load like climing a mountain I will warm it up.

It not good to idle my diesel to long at low idle.

Normaly I idle to air up and start the fast idle after about a minute. I idle for about 3 minutes.

If I have been running awhile I let it idle at fast idle for 2-3 minutes to cool down a little. But my unit at fast idle cools down fast.

This is the winning answer.

When I am getting ready to leave in the AM I have to start the motor so i can 1. bring in the slides, 2, bring up the jacks then 3. fill the bags and air up the rest of the system, in that order, so that is at least three four min or longer. I don't sit around letting it idle, as soon as my system is aired up i pull out. I normally wait till after quiet hrs. So it is what it is.

We own a 20 year old diesel. We do not sit an idle. We rarely start up before we are actually in our seats ready to go. 99% of the time we wait for the airbags to come up, couple of minutes,, and head out. In rare instances if it is extremely cold, we may wait a bit longer. Normally we donít leave until 9am.

It's recommended to let diesel idle for at least 5 minutes to allow all fluids to warm.

My 1992 Cummins manual defines excessive idleing as being more than 10 minutes, and they warn against excessive idleing. They say that with repeated really excessive idleing your engine can experience cylinder washdown.

The specified procedure is to let it idle a couple of minutes, then proceed with restraint. They also recommend letting it idle several minutes after running under load.

Note that this engine is an oldie, pre-Cambrian I think, and Cummins said to avoid excessive idleing way back then.

My Diesel Prevost needs to build air pressure for the suspension and belt tensioners, I am truly sorry that I caused missed sleep but I cannot roll until I have Air.

I have an old school diesel. It has to run a good ten minutes (yes, it really takes that long, and no, I'm not concerned, or looking into it) to build up air for the suspension and brakes. It's also getting lots of expensive parts like the turbo, exhaust manifold, tranny, etc up to temp.
It's right in the book.

Also in the book is a 5 minute cool down idle after the coach has been run at speed. What they mean is making boost and spinning up the turbo. Last thing you want to do is spool up the turbo to high RPM, and then shut off its oil supply. A 5 minute idle lets the turbo cool down, and slow down as much as possible before removing it's oil source.
This is also in the book.

Most diesels at idle are very quiet. I've overnighted at plenty of truck stops and rest stops mixed in with trucks that are idling all night long.
Didn't seem to be a problem to me. Still able to hear the TV just fine, still able to sleep.
My coach is parked along the side of my house, and when it's airing up, and I'm in the house, I can barely hear it.
IMO an idling diesel is not that big a deal.

I don't have a Harley, but my ride is a street legal 4 stroke off road bike.
It's a 650, single cylinder, pretty much 'half a Harley'. It's got a carb, and not fuel injection, is a kick start machine, and is very cold blooded. Once it has cooled off overnight, it's gonna have to idle for a while, otherwise it will sneeze, and die, and you'll be kicking it some more.

Let's go back to what some call, 'excessive idling'.
If I'm just fueling up, I'm not shutting down. If I'm running into Mac and Don's fast food lounge for a coke and a bag of fries for the dogs, I'm not shutting down.
IMO there is no reason to. Shutting down just adds unnecessary thermal cycles and actual engine wear. The wear come from moving parts that do not have a cushion of oil to float on. The majority of engine wear occurs during start up. Less start ups, less wear, less thermal cycles.
It's funny how political correctness has creeped into everything. Now we are going to claim it hurts the engine to idle it! There was a time when no one would question a guy idling a diesel, it was SOP. OK, sure some of these new engines have pollution control parts that can't handle idling, but it's not hurting the actual engine. I guess that is the price you pay for 'saving the planet'.
Hey, you do you, and I'll do me...

Did you know that the railroads don't shut off locomotives unless they have to be shut down for maint? I've seen cases of tied down, unattended loco's idling for weeks, even months. If this was harmful to these very big, very expensive powerplants, the RR bean counters would have long ago put a stop to this practice.

Now, let's talk about all the jerks at the CG that sit outside all night talking loud, playing their music loud, and having rock concert type lighting on their coach wrecking the night sky for everyone. Oh, and people that are early risers that let their screaming children out to play at 8am, while the rest of us are trying to sleep.
Personally, I'll take an idling diesel over all of that, any day...
Well said!! Campgrounds are generally noisy places. Too many people packed in too close together. For those who gripe and complain, I would suggest explore the Boondocking option. Now that said, I don't make any more noise than is necessary. No animals, no kids, no motorcycles any more, don't sit out late talking loudly and hooting and hollering, but I got an old truck as well, and you don't start it up and take off. Now, I arrive, stay at least two weeks and never start the truck until the day I leave. If that is too much for some of you, well, it can't be helped.

Hopefully some of the diesel pusher crowd will read this and think about what the rest of us have to put up with after you sit in front of us running your stinky diesel while you hook up your toad and say your goodbyes. You donít need to warm them up for half an hour, be more considerate of others.

It's always the guy with the 100 watt porch light that is complaining about everyone else!
How about you invest in a diesel pusher first! Then call us when you realize about diesel engine care!
BTW, please make sure that your kids stop riding there bikes through my spot!

Yes, us diesel owners need to have engine running while we close our 4 slides and lift our jacks. After jacks lifted, it takes about 5 min to get back to ride height. As mentioned with others.
