It's getting harder and harder to buy Jet A around here due to the increased scrutiny airports are receiving from TSA and DHS. I can get kerosene in 5-gallon cans from the hardware store for $9 per gallon, or I can buy it from the pump at a local convenience store for $3.79 per gallon. I've never gone the latter route because I'm afraid of contaminants in the ground tank, especially this time of year when the kerosene in the ground has probably been there for months.

Am I being silly? Anyone out there routinely use kerosene from ground tanks without problems?
