What temp idle to prevent gelling?

If you're only getting fuel up north, the fuel has additives in it already. Now if someone fills up in Texas and gets into the sub zero temps, they might have issues.

And here come the assumptions!


That being said, again: this is about what temp you need to idle to prevent the fuel from gelling. Not what to do to keep your truck warm. In retrospect, it's healthier for the truck to leave it shut off and then warm it up as you drive it...... But what do I know. As you said, I've been doing this for 16 years. Funny how it's only the rookies that are 'correcting' me.

 

Note to future posters:

When I said #2 diesel gels at 15°F, I was referring to #2 diesel WITHOUT any additives. Fuel service stations up north have to put additives in their fuel. Why? How hard is it gonna be to pump fuel when it's gelled? So next time someone calls me out on misinformation, or next time someone says I don't know squat after 16 years of driving, pick up some reading comprehension skills and take a double-take of what I said.
