Why leave a diesel running while filling it up?

[MattB]

I've never got a good answer. I understand if it's below 40 degrees, or the truck isn't warmed-up yet, but what if you have been driving 3-400 miles, and the temperature is normal outside? Is there a benefit to leaving your truck running?

Keeps the a/c kicking!

^yup. Dont worry, youre not gonna accidentally ignite the diesel because it running or with a static spark from your shirt rubbing on the car like you see in worlds craziest videos crap. Diesel doesnt ignite easily at all.

Gotta keep the beer cold..

just make sure you use the diesel pumps so the guys in diesel trucks have to wait on you.

Ever had to replace the starter on a diesel? Me either but I know they are heavy as crap and expensive. That and idling a diesel barely uses any fuel at all compared to a gas engine.

I bet the main reason though is so you don't have to look at that "wait to start" light for 30+ seconds. They nearly all have one and it doesn't matter if it's hot or cold, it's going to come on.

You do not have to wait for the light to go off to start the truck, especially if its already warm.

The Glow Plugs and Grid Heaters are not even for cold starts, they were designed to heat up the cylinders before the first start to burn more of the fuel the first few strokes to cut down on emissions.

My 6.0 starter was the same weight as a factory 5.0 starter from 89.

I don't wait to start in the summer, or when the engine is warm.

I do turn my truck off when I'm getting fuel.

The fuel it consumes starting and fuel consumed idling is practically equal.
Thus, why bother shutting it down if there is only a negligible difference in costs?

That's kind of open ended. Fuel consumed during startup = fuel consumed idling for how long?

What about everyone within 200 yards of those stinky, rattling biatches?

Wrong. If its cold enough they are a neccessity to get the bastards to start. Take it from me, I just moved back down here from Philly and i could damn sure tell when my GP relay went out! Its rare that it gets cold enough down here, but grid heaters and glow plugs are definitely meant to assist in the ignition of the fuel when the block and cylinders are stone cold in the winter.

That would be my damn iPhone helping...
