Should I be idleing?

I idle under 20 and over 75.

 

hah i'd idle at 40 or below justn to stay warm! dang the fuel!

 

Most anti gels will go down in to the negatives, but its good to keep the tank stirring. A good steady wind even at 10 degrees will gel it up no time. But like super said, #### the fuel, stay warm...lol

 

I would generally idle for an hour every 4 or 5 hours at really low temperatures. The qualcomm has a sensor display of many things, one of which is fuel temperature. I've watched it get down into the 40's and idling will get up over 100 degrees.

 

Not silly. You can buy them at the truck stops. Just look at the bottle for how many gallons it treats. Split em between your tanks (I assume you have 100 gal tanks?) when you fuel, that way it gets mixed in good.

 

Fuel in southern states is not always treated, as for fuel gelling, somewhere between 10 and 15 degrees is the usual temps that it will start to gel depending on the fuel quality. In the winter if your not sure if the fuel is treated , add anti gel, you can ask at the fuel desk if their fuel is treated. I always carry fuel treatment in a side box so I can add it if I am buying fuel in the south and headed north.

 

it's not the fuel in tank I worry about,it's those little lines to the injectors that gel first. had them gel years ago when it was -40 below up in Quebec. had to stop every 20 minutes or so and the lines would thaw from the heat of the engine.lol. learned my lesson, add the additive under 15 or so. I was running southern fuel with no inline fuel heater or additive.

 

In case you're wondering what the bottle looks like, this is what I usually get at the truck stops.
