Here's a question for all you dieseloids: At what temperature does fuel gelling actually become a problem?
There are an awful lot of people claiming gelling problems at temps well above 0 degrees Fahrenheit. My job entails turning diesel fuel into happy trails at 41,000 feet, and we're only required to keep our 'diesel' (they call it 'Jet-A') warmer than -40. We don't run Jet-B or additives. Now I realize that jet fuel's not precisely the same as diesel (I do know of one operator that ran diesel in their King Air for years with no apparent problems), but I can't see a 50 degree F difference in the freezing point.
Is it just water freezing in the lines or filter? Or is the stuff we run in our cars so crappy that it gets gunky at 15 degrees? Any wisdom would be appreciated.
