We all know pump gas is shakey for quality at best and will only get worse with oxygenated fuel stratisfieing? out as it sits so what is so bad about avgas??? I have heard that it is TOO DRY but what does that mean??? I can get 100LL for around 4.00 a gallon and can rest somewhat assured that the quality is a far cry better than what I get at the pump and it will not flatten out in a couple of weeks so other than the lead screwing with the pipe probe what is wrong with running it in a pump gas turbo???? THANK YOU garry
