Smilin Ed, in respect of your last (1261), I think
not.
"Do I interpret this discussion correctly? Is it being said that whatever caused the freezing point of the fuel to be much lower than typical caused the fuel to not be properly combustible?"
I'm not a fuel chemist, just a pure chemist of sorts and hope to be corrected if wrong by those in this thread more knowledgeable than me, but simply shortening the average alkane chain length in the fuel will be the basis of the lowering of the freezing point/waxing point temperatures,
not the addition of non combustible additives.
Technically such changes will alter the Heats of Combustion a little but never so as to render the fuel non combustible. That the fuel was within spec is key.
The arguments for and against the effects of water scavenging additives (which are usually ether like molecules derived from ethoxyethane and inherently themselves very combustible) and / or fuel having become stratified, have been rehearsed at length in earlier posts on this thread.
