My little TDI jetta takes for freaking ever to warm up and idling doesn't help any. Starts fine down into the 20s which is the coldest it has gotten since I bought it. I'd like to get a plug in coolant heater not so much to make it easier to start but just so I have some damn heat while driving to work lol. Thank God for the seat heaters.

Meaning impossible. Leaving a diesel running isn't much of a safety concern outside mechanical failure where the vehicle can get away from you.

Yup. He's not worried about it, because his fuel isn't flammable, like gasoline. Hell, if he were smoking, he could put his cigarette out with it!

That, and he was probably just trying to piss you off.....because he COULD. :sneaky:

As far as you know, he had to jump start it that morning after leaving his lights on and couldn't let it turn off. Doubt your little car battery would help jump it if he needed another!
This. Why do people have to be such asswipes and assume the worst? I'll tell you why. They are fucked up in the head and think the world revolves around them.

If you assume the worst, you are seldom disappointed.

Furthermore, your predictions are usually uncannily accurate.

I filled up the other day... woman in front of me let her dodge journey run the entire time. Not only that, but she sat in the vehicle while the pump ran. Putting us all in danger as she 'charged' herself up on her cloth seats.

the diesel truck owner is a non issue

When I lived in North Dakota, everyone left their vehicles (gas or diesel) running while fueling in the winter. And in the five years I lived there, guess how many gas station explosions I heard about. You guessed it, zero.

Didn't Mythbusters debunk this nonsense?

They confirmed that a static spark can easily spark a gas fire. Busted cellphones, though.

Mythbusters tried to recreate a static discharge ignition at a gas pump because they knew it happened all the time with statistical proof that it happens more often to women who get in and out of cars. I think they said cellphones were statistically proven too.

No.

I'd not cite mythbusters as a reliable source of anything, but you should probably review your source material nonetheless if you think that the conclusion that they reached was that there was any danger.

edit: However, in regards to static, yes, that would be the highest risk possible really. It is hot enough, and in the exact location needed (if you get it from touching the handle/area around the handle after building up a charge in yourself)

Cell phone, no.
I didn't cite them. I mentioned that they cited an existing statistical conclusion even though they could not reproduce it. I checked and they did not say the same for cellphones. That's why I never definitively said they did.

Let's see what NIOSH has to say about gasoline.

Fl.P: -45°F

UEL:
7.6%

LEL: 1.4%

VP: 38-300 mmHg
So if you can get the concentration in air between 1.4% and 7.6% and the temperature above -45F and add a flame or spark then boom.

For diesel NIOSH don't say so we'll go to Wiki.

Diesel fuel
LEL 0.6
UEL 7.5
FP>62 °C (143 °F)

So for diesel we have to have 0.6-7.5% concentration in air and a temperature of 143F for a spark to ignite diesel. Usually not an issue except right on the pavement in the sun in high Summer when surface temps can easily exceed 143F.

No it doesn't. More people buying them only increases the price if supply is limited and there are no competitors. Otherwise, it increases the economies of scale and DECREASES the price while increasing over-all profit.

Larger orders, cheaper product.

The Diesel engine is an almost $8,000 option on the Ford F-250. Gee, I wonder how many miles you'd have to drive before that option pays for itself... especially if all you do is drive yourself to and from your white collar job.

I dont see the big deal, I spent one winter up north(northern canada) Where it was always below -30c and literally every single vehicle that was used was never turned off for the whole time i was up there. They were left running while fueling up,and in your driveways overnight unless you had a heated garage to store it in, and no one ever stole anyones vehicle.

People just dont turn there vehicles off when it gets thats cold because after 5-10 min it wont be starting again unless you thaw it out.

So while i dont really see it being any kind of a hazard as nothing bad ever happened while i was up there and i wintnessed hundreds of vehicles being fueled while running if it isnt cold enough to warrant it i also dont see the need for peeple to do it year round.

It is amazing how quickly some people will judge others.

Wearing a cowboy hat: They like the way it looks? Who gives a shit?
Leave diesel running: Maybe force of habit from when they had a 1980 diesel truck to work with, and they were extremely hard starting (my parents had a dually diesel that they actually had to plug in every night or it would not start the next morning)
Truck accesories: What is wrong with a hobby?
Fumes: I am certain this was just facetiousness

I don't have a diesel, but jeez the stereotyping behavior like this is atrocious.

I also think the OP has some issues with jealousy.

Jealous of what? dumping $90.00 bucks of fuel into a truck every 4-5 days?*** lol yea ok.


*** based upon my location being a bedroom community and he was driving into denver/Boulder/Greeley for his job.

I always leave any vehicle running at the station when pumping. Don't like it? Too bad.

Another option I didn't see mentioned was the turbo. AFAIK all modern diesel PUs are Turbo Charged

In some cases, especially when towing or engine under a heavy load it is reccomended to let the truck run for a few min to "cool" the turbo down before shutting the engine off.

They even make aftermarket products to automate this process..
http://en.wikipedia.org/wiki/Turbo_timer

Now the "necessity" to do this is debatable, as is leaving it on to heat, cool, or because its hard to restart. AT LEAST there are a few plausible reasons that dont include simply being an inconsiderate C**T to everyone else around you.

For my money, there is much "lower hanging fruit" of gas station antics and asshattery..

This would be the dipshits who sit there with their stereo on full-blast while pumping their fuel.

(yes, I also saw the thread about the people getting shot for doing this, save the link)

holy shit do they think they are special or something? this morning while i was getting gas some asshat cowboy wannabe wearing a suit pulled up in his giant ford 350 power stroke pickup to the other side of the pump i was getting gas. asshat wannabe cowboy in a suit leaves his ANNOYING LOUD ASS truck running while he gets gas and this MOFO is LOUD is rattling my skull. Not only is it LOUD but the exhaust is choking me out. I think its the winter blend diesel because his exhaust didn't smell like diesel exaust it smelled like i just stuck my head in a coal fired oven and took a big lung full of coal smoke.

so what gives? do these guys think they are special because they drive a diesel truck and are playing mr 18 wheeler or something?

Drank too much last night?

I'm still waiting for someone to explain to me just how exactly your car is going to blow up by leaving it running while pumping gas.
