What comes from the refinery is mostly clean fuel. Over a period of time. The tanks at the gas station accumulate junk over time. Everytime a tanker dumps it load. It stirs all that chit up. It takes a couple of days for it to resettle. The kicker is how often does that tank get refilled? If it's every couple of days. The junk never fully settles out. If I remember right. The pick up pipe is about a foot from the bottom of the tank. This is to allow for a accumulation of water and junk. The station is required to stick the tanks daily to check for fuel level and water level. When the water gets to a predetermined level. They will come in and pump the water and junk out. Most tanks will have a few inches of water in them.
My brother used to own a gas station.
