Why must diesel pickup truck owners leave their truck running while getting fuel?

[SyndromeOCZ]

so you sit and wait 15 minutes to turn it off every time? lol yea bullshit.

Its called a turbo timer. Most performance chips have them now days, you can set it up so everytime you turn your truck off and remove the key it will keep running for 5, 10, 15 minutes or how ever long you want. You can also set it so the truck wont turn off until your EGT's drop below a certain temperature.

I've got my turbo timer to shut my truck off when my EGT reaches 400 F. Sometimes it takes over 30 seconds before it shuts down. I can be out of the truck with my key have it locked and half way into a grocery store before it shuts off.

I have a diesel truck the turbo is oil cooled and requires about 15 mins to cool down properly when it has spooled up especially if coming off the highway. if you shut your truck down prematurely with out cooling the turbo it could fail and is very expensive to replace. If you where to take a thermal camera to the Turbo it would show lots of red and some white areas.

15 minutes? You gotta be fucking kidding me... it's 2013 for Christ sake! You're telling me that we don't have water-cooled turbos in a $50,000 modern diesel truck like they do in a freaking $20,000 Subaru?

i can top that. I watched a guy light up a cig while pumping gas D:

I was amazed that someone couldn't wait 5 minutes to start another cig while pumping GAS WTF.

i was kinda hopeing he would explode. hmm

Way back in the late '70's when self pump started to get phased in I saw an older guy in one of those cars that had the gas fill behind the license plate who had a 12-13yr old trying to fill the car, the kid pulled the plate down but didn't unscrew the gas cap and was pumping the gas on the ground!, here comes dad out of the car to fix the issue WITH A LIT CIGAR IN HIS MOUTH!, I didn't even wait till he got to the back of the car, I just slung it in drive and hauled ass!..

I think the water cooling is used to cool the oil in the turbo to prevent coking.
The bearings are still oil cooled.

Diesel trucks are usually built for rougher duty. Water cooling adds another point of system failure and some designers have not finished testing the designs out yet. If it proves durable enough it will be included.

The engine in my pickup truck has been in production since the 1960's I believe. And no majors changes till 94 when it was fitted with electric fuel system.

Mine is a 1991 with ~800,000 miles only have had to replace the water pump. Gets ~24 mpg empty, 21 mpg with a 1500 lb. load in the bed, and 12 mpg with a 1500 lb. load in the bed and towing a 7000 lb trailer.

Running your engine, using your cell phone, or even smoking at a gas station isn't going to cause anything bad to happen. Sorry, it just isn't. Gasoline is not some super volatile ticking time bomb. It's actually reasonably difficult to burn. (I said reasonably). That's part of what makes it such a widely used fuel.

edit: note that I say "isn't going to". In theory, in extremely specific scenarios which are almost 0 probability at a real gas station, one of these things could flash ignite some gas vapor.


That said, there is little reason to leave your engine on while refueling unless it is frigid out.

I was watching a extra on a DVD where the actor tosses a cigarette in gasoline to make something blow up, and they couldn't get the gas to light. In fact the cigarette would go out when it went in the gas. They had to rig something to simulate it. Or maybe that was an actual scene in a movie. I dont remember, but the gist is yeah, gas is supposed to be hard to ignite from a cigarette.

My dad used to bitch about this...isn't it because the engines are hard to start or something?

Used to be.

Also, it used to be (before fuel injection) that leaving a car idling for a couple minutes used less gas than starting it.

In both cases, modern technology has fixed that problem, only to be foiled repeatedly by "Daddy said ____, and his daddy said ____, so there!"

 

[IronWing]

And my question is... why do you even care? So they spend stupid money on stupid stuff for their stupid truck. Big friggin whoop dee do. Why does that bother you so much

Posting in a necro thread (though a relatively minor necro in comparison to some)

The same reason we bitch about Texans: they are noisy and they smell bad.

haha I didnt want to read the thread anymore but remembered that cigarette anecdote when I saw Ferzerp's post. Guess you guys had it covered!

also the odds on diesel blowing up is far far less then gas blowing up.

This. Diesel is not that flammable. It's thick like vegetable oil. You can throw a match on it and it may or may not start on fire, depending on temperature.

I can just imagine the OP flipping out at McDonalds or something. OH MY GOD YOU ARE RUNNING THE ENGINE WITHIN 3 YARDS OF 400 DEGREE OIL!!!

 

[justoh]

Do all diesel truck owners own the same, single truck? Don't understand the title.

hey mushhead, if you read my OP do i mention the truck blowing up? or that im at all concerned about that?? NOOOOOO

my post is about the asshat diesel pickup truck owners who annoy the shit out of me. sorta like your reply.

PS. Diesel is not thick or like vegetable oil.

I believe it is due to the amount of diesel required to idle the engine while fueling up is a lot less than the amount required to turn over the crankshaft and start the engine once it has been turned off. Due to it's efficiency you save fuel by running the engine while fueling up over stopping and restarting it.

This... And this was typically the case with big rigs, but with advances in ignition and engines in general, I wonder if this even holds true today on the smaller pickups. One would think there would be no advantage to leaving them running from a fuel consumption standpoint.

It can be depending on the temperature. Diesel will turn into jello in winter, that's why as kids if you went around and unplugged all the school buses, you did not have to go to school the next day. :biggrin: Not that I ever did that.

 

[jjsbasmt]

Why isn't it just as simple that there are dumbasses out there that think they are better than everyone else since they drive diesels and don't have to obey law and common sense to turn off their vehicles at certain times like refueling. A number of gas driving vehicle owners fall into the same category. There are good reasons that laws exist concerning leaving unattended vehicle running and running while refueling.

The magic number is 40F. Below 40F, it starts to gel.

Because cars only backfire when idling, never when starting to stopping. :hmm:

Hi everyone I stumbled on this page and I though of setting you yanks straight because your clueless.

Diesel is a different fuel to unleaded petrol, subsequently when you fill a diesel tank the diesel foams like waves in the ocean. If it hits a still surface it foams more than if it hits a moving surface. You belly flop into a still pool in you back yard. It hurts more than a straight dive into moving water ( like if your mates are splashing in the water)

What keeping the motor running does is it keeps vibrating/ shaking the truck, bus what ever, and with it the fuel tank so it minimises the amount of foaming by decreasing the tension on the flat layer of diesel in the tank.

If you didn't keep you motor running it would take 3 times longer to fill up and half your diesel would end up on the floor.

Also you almost light a bonfire next to your truck while filling diesel

DO NOT TRY IT. I would make that clear because you yanks need to be told everything. In Australia we have this thing called common sense, which even here in Australia doesn't exist anymore, lets call it uncommon sense.

The static electricity build up can create a spark between your car and the fuel nozzle that's why petrol cars have to turn off before refuelling. When I refuel my petrol cars I always turn off the motor
When you fill your petrol cars you see the evaporation?
That vapour is what will catch fire if you smoke next to your petrol car.

Diesel on The other hand Is like motor oil, it comes out so low in the refinery that it doesn't evaporate

I have set you yanks straight and done my public service for today I'm going to bed because its 3.40 in the blessed A.M. Here in Brisbane

I wish you health and happiness

Thank God you updated this thread. I have not slept a wink since 10-22-2013 because I was so worried about this. I can finally rest, AHHHHHHHHHHHHHHHHH.

Lol.

It's a safety thing as an unmanned car can get away from you due to the driver being a dumbass (they're out there). Shift to park, shut off the engine, it's not that big of a deal. Plus diesel smells like ass.

Oh, thanks for necroing btw!

 

[smitbret]

There is so much balogna in this thread. Holy crap!!!!

I don't even know where to begin....

 

[wabbitslayer]

All this is sad and all, but on the other hand, it's so nice when a truck burning bio-diesel pulls in next to you and leaves his motor running and everything smells like french fries. :awe:

 

[smitbret]

Yeah, we've got a guy in town that owns a couple of fast food restaurants. He actually converted his diesel to run off of the frier grease. Just filter and dump it in. Smells like French Fries everywhere that he goes.
