After reading lots of post on this forum about fuel I would still like to know which kerosene would be better as far as dealing with contamination(algee,water dirt......ect).One from a 50 gallon sealed drum or out of the pump from BP gas station.They don't have the crown or what ever it call at home depot and the airport guy's ask to many questions.Also is there something you can add to fuel to fight algee.And how big a problem is a little water as far as flame outs go.
