The new fuel REALLY attracts water causing problems with saw performance , I guess it's good for the saw shop ...:
Is there any reason NOT to use 100LL in chainsaws? I mean, would it damage the saw?
Actually the reverse is true .Av gas burns slower therefore prevents or curtails pre ignition . In addition to higher compression an internal combustion gasoline engine is effected by altitude regarding pre ignition therefore the reason for av gas in the first place .Likely you will get pre-ignition knock using it in a stock saw, the fuel/air mixture igniting too soon before reaching higher compression.
Mike, High alcohol content fuels have mixing issues with oil making some autoracing fuels problematic. I don't think there should be any mixing issue with avgas. 82UL is about the same as regular unbleaded pump gas except for stricter vapor pressure control.....it would be perfect except most of the new generation of saws require higher octane per the makers. 100LL has plenty of octane rating but it is leaded so we will get some lead exposure from the exhaust gases.
