Looks like you have proven that the guidance to turn off your engine while refueling has been effective! QED:icon17:

Damn fine point there.

So, it is possible that if gasoline spilled on the hot exhaust pipe it could autoignite. It is also likely that turning off your engine would allow the exhaust pipe to cool the 25-50 degrees below the autoignite temperature fairly rapidly.



From what I read the reason for the varied temperature of autoignition has to do with many variables. The temp of the gas, how much gas is there (thin film vs someone pouring a bucket of it) so I'm still not sure that gas hitting the tailpipe would cause it to ignite. That being said, I'm still going to turn my car off when fueling, this just seems like a really interesting topic.

It's been my experience that typically a rule is set because of an incident. Like when you see the warning label on a hair dryer telling you not to use it in the bath tub, some idiot actually did that and now they have a label, which leads me to believe that something cause this rule to be born. I'm just curious what it was and how it holds true today. All the same thanks for the info about exhaust temps.

Ummm I don't know if you can read but that's what I was stating that I was upset about. You've probably never heard of natural selection so that's what confused you? Look it up.

The "Turn Off Engines" sings have been at gas stations for decades because back in the day it was possible that a running engine could spark a fire that could travel back through the system. Nowadays it is almost impossible with newer vehicles. It's still highly advised that you don't because of freak occurances. The only exception is vehicles with diesel engines. Those can be running and NEVER cause a problem.

EDIT: It's your life though and if you think the extra 20 seconds you save are worth playing a death lotto with really, really, really bad odds of "winning", go for it.

Ahh, of course...because we all know that a car's exhaust-pipe is significantly cooler 30 seconds after shutting off the engine than it is while idling, thus making it safer in the event of "splashing gas." :)

Since that one's moot, can you think of another reason? As 300ShooTTer mentioned, gone are the days of where it was possible for a spark to travel back up the fuel-system while the engine was running. But guess what...if that were to happen, you're screwed anyway, pumping gas or not.

I will note that I do not condone leaving your car running while pumping gas, nor do I regularly. I just mentioned that I have done it a few times in the past when I knew I would be stopped for less than a minute.

BTW...quit splashing gas everywhere when you fill up. ;)
