I've only bought ground kero once & it was contaminated, some gritty looking residue that was fine enough to slip through my filtering material & it always looked cloudy with this crap. I ended up giving it away to a guy to wash greasy parts with but wasted my oil which I put in the drum previously.

For the Aussie readers the servo was the Liberty on the corner of Gilba & Targo roads, Pendle Hill in NSW - avoid it!

Looks like you US guys have better luck, kero is just about extinct in OZ except in little bottles from the hardware store. - John.
