In the meantime, if we all start paying MOGAS prices, if you take fuel as around 2/3 of the cost of flying a light aeroplane, and MOGAS as 2/3 of the cost of AVGAS, you'll shave around 15-20% off the cost of GA flying.
That would, despite a lot of fuss in the short term, be a really good thing.
Fine in theory but don't you think that Mogas would creep up to the price of Avgas? Due no doubt to 'difficulty with supply and production blah blah'
Look how Diesel has shot up in price over the last twenty years or so. For no reason whatsoever other than demand.
