[Healeys] Gas and ethanol

[Bob Spidell]

Well, avgas doesn't have alcohol in it, if that's what you mean.  But, I 
think you'd have problems running exclusively on avgas, as it still has 
lots of lead in it.  It would likely foul your plugs and/or rings (with 
elemental lead) eventually, esp. since I doubt modern auto oils are 
formulated to scavenge lead (Mobil AV1 full synthetic aviation oil was 
pulled from the market due to it not scavenging lead properly and 
causing some engines' rings to gunk up).   Plus, avgas is up to twice 
the price of auto gas, you'd have to transport and pump it, you'd owe 
the gov't road taxes, etc.  It has a lower Reid Vapor Pressure than 
autogas, and would make for hard starting in a cold climate.

Best bet, if you're worried about it, is to replace rubber components 
with modern parts.  I'm sure I've run some gasohol in my BJ8 since you 
can never be sure, and I've had no problems.
