If you use a 2-stroke engine, bear in mind the high lead content of AVGAS 100LL will cause long term harm. I read an article in a motorbike magazine many years ago which compared unleaded with AVGAS and the old 4-star leaded petrol; AVGAS contained about 3 times as much lead as the 4-star(which was abolished many years ago, so how long before AVGAS goes the same way?)!!
