Some more stuff from old post on TT:Anyone who claims that the lead deposits are bunk had obvioulsy never torn apart a motor after using leaded fuel. I ran nothing but unleaded pump gas in my WR250Z motor was alwas deposit-free. Started running AvGas (100LL) continued running it for a whole season. Tore the motor down, WOW what to yah know, lead deposits on the rod, coating the intake ports & sides of the case next to the crank. If I had pic I'd post it.Avgas also has a high alcohol content, to displace moisture. It is also formulated to enable high altitude operation. AvGas, Race fuel & Autogas are very different in formulation, about the only thing they have in common is that they burn and let us go fast
