Just cause you are getting Jat A from an airport is no reason to suspect it is super clean! I get mine from Slidell airport here in Lousyana. You would simply NOT BELIEVE the crap I find left in a five gallon drum. I expect someday to find the airport guy's lost tennis shoe!

Filter, filter, filter!
That's why I get it from the gas station, it is much cleaner.
