idle time

i've been searching, but haven't really found a good answer yet. I'm wondering when/how long it is fuel efficent to let the truck idle and when to shut it off? I'm looking into getting gauges so that i know how long it takes to let it cool off.

Cool off as in EGTs? I usually shut it off 375 and under. Doesn't take much to get to 375. Longer to get to 350 and under.

It's always cheaper to shut it off right away. But cheaper by maybe a few cents. I've heard these trucks use somewhere around 1/2 a gallon per hour? Which is 1/120th of a gallon a minute. So using about $3/gallon (it's like 2.70 here), that's $1.50/hour. Roughly .025 cents per minute. SOOOO it doesn't matter Compared to old IDIs and such, the amount of fuel used to start up is negligible which is why I'm not even accounting for that.

i shut mine down when it hits 250*
sometimes when you get off the freeway pulling it takes a while to cool down

Most trucks will excede 250 at idle even from cold start up..... When you have the gauge, just idle till at 350-ish. Or about a minute after a long drive.
