I spent years driving a tanker and delivering av gas to assorted general aviation airports (FBOs) in the PNW. It's blue; it's clean and the consignee will have done a white-bucket test and a gravity test on it. After every load British Petroleum, whom we hauled for, required that every compartment be bucket-drained and tested for water before the next load. I kept a 5-gallon can in my trunk and netted that much every day that I hauled av gas. I had a BMW 78 320i and a Norton Commando motorcycle at the time and both were very happy when I came home with a can of av gas. I also ran it in my 51 Chev pickup with a 235 and 8:1 compression. Never a problem. During one fire season I had a daily run from Seattle to Redmond OR to fuel a 4-engine DC6 outfitted as an air tanker that used about 10,000 gallons a day. This went on for over a month. Log books were exempted by the state on orders from the Governor. We ran as many hours as we could stay awake. The Norton and Beemer were happy.

I also hauled jet-A for B-P to all sorts of locations, mostly helicopter applications: logging shows, fire fighting and some FBOs. Same story as av gas on quality; same bucket-drain requirement after every load. The difference was that the drained jet fuel ended up in my old Mercedes diesel car. It was quite happy and I would lube the injection pump with a qt. of ATF that I got the same way as jet fuel; that is until I realized that the state fuel-tax authority could sample diesel in cars and trucks, checking for un-taxed, red-dyed diesel. By that time we were hauling bio-diesel and I used that as a pump lube.
