Just thought about asking who still adds kero to there diesel fuel for the winter? I guess My father in law hasent learned yet still, that adding kero does nothing to protect against water in the fuel. 2 years ago his tractor died when I was plowing snow for him with it. Apparently there was a layer of ice in the tank, when I poured in fuel, after 2 gallons it over flowed. The fuel couldent get to the bottom of the tank because of the ice. After that I left the tractor there, his problem not mine, My tractors run fine, with power service conditioner, and never used kero. He thinks the tractors crank over easier with kero???? Not true. Anyway I asked him last knight if he added any conditioner to his tractors and he said no, I added Kerosene... I guess you can lead a horse to water, but you cant make her drink it.!
