Ford recommends plugging-in 6.4L trucks
For all you folks that live in this kind of climate, this is what Ford recommends.
6.4 PowerStroke cold weather starting procedure/recommendations:
With the new high pressure fuel system, the 6.4 PowerStroke starts at much lower temperatures than previous engine modles. To ensure proper bearing lubrication in ambient temperures below -10 degress it is imperative that the engine block heater be used. It is recommended the block heater be powered three hours prior to starting. In addition, it is recommened that a light oil such as 0W-40 or 0W-30 beused. Ensure the API rating of the oil is CJ-4. SSM 19603. CI-4 Plus is permitted if CJ-4 is not available, but severe duty oil change intervals must be followed.
