HAHA, no im not stealing it.
i work in the aviation industry, thats all
and i know a bit bout the fuel,
it burns slower than 98 therefore increasing its detenation charateristics, and in turn it burns hotter, and killed my poor litle civic engine's valves
it doesnt make the exhaust go red but when running really rich i have seen it going 'sort of white' but mostly black
its got alot of lead in it, say the old leaded fuel for cars was like 0.05g of lead or something, avgas is about 6g (my numbers my be a little wrong) thats why they are trying to get rid of it just like in cars
it has a lower reid pressure, cant be bothered explaining, plus it doesnt matter if your running it in a car.
