Well I ate my words on fuel additives this morning.

If it that’s cold I would cover my grill too. Less problems with regens if you are driving newer truck. Better fuel mileage with older truck.

 

You’re good down to about 0 with winterized #2 but -17 is well below the CFPP (cold filter plug point) and approaching the cold pour point. The best idea is to run #1 fuel when it gets that cold. Will start easier and burn better in cold temps. You’re good down to at least -20 CFPP with that stuff.

 

#1 is not available everywhere. You just have to put more additives (check the label). I heard some people use kerosene also, but I wouldn’t try it on newer trucks.

 

I would also take a look at where you got the last fill up on fuel. Maybe it wasn't treated as well as it should have been?

 

Agreed. I learned that the hard way also. I get my fuel from TA or Petro when it’s that cold.

 

Heck, it could be as simple as the wind was blowing from the front of the truck. Kept adding cold air faster than warm fuel was helping.

 

That’s why I

That’s why I cover my grill at these temperatures. Some people also put a heavy boot to cover their metal fuel filters. But how can you insulate your tanks?

 

No but it regularly is in places where it typically gets that cold. Any Town Pump Pilot in MT will have it. Most places in the Dakotas and MN will also. I have even seen it in ID along I-90.

They do not sell it anywhere around me since it doesn't get that cold really ever, but one place does have a kerosene pump would also work with a lubricity additive. That is all #1 fuel basically is anyway.
