I am curious about the whole plugging in a diesel truck in the winter.
I live in a condo (on the second floor) with no option of being able to plug-in... so with that being said, is there an option out there for me to not plug in my truck? thanks
The fuel stations in your area will automatically prepare for colder winter temps by changing the diesel fuel additives at the pump to prevent the diesel from "gelling" in frigid temps. This is where waxes in the fuel actually solidify due to low temperature. This typically occurs in the fuel bowl and the wax solids block the fuel system and prevent cold weather starting.
Depending on what year Ford you purchase, it is also a common practice for guys to use an additional additive when fueling up...one that is rated for winter use as an additional safeguard against fuel "gelling".
Also, if you are considering a 6.0 then not being able to plug in a block heater will likely increase the chance of "stiction" issues with your injectors. This can be mitigated by using a product called Archoil AR9100 which is added to your motor oil at each oil change.
If all your system are good and the engine well maintained you shouldn't have too much problem. I add my truck in -35*C not plug in, didn't have any problem. Lucky me i was in the middle of nowhere ???
