Trouble is petrol is no longer what it was. No longer can you go to something that's been standing for 5 yrs and start it up, because today's petrol is a blend of mysterious molecules that die young. The component that gets you started evaporates and the ethanol (why's that used?) hygroscopic. I think the methanol route is the way to go (yes, I know that's hygroscopic too). And all for what? To satisfy the easily led who go around thinking fossil fuel is damaging the planet because they read somewhere that man is causing the planet to heat up with CO2. Sad they never studied science, which proves CO2 rise occurs around 600 years AFTER global warming. It doesn't cause it, it's a consequence of.
