I know some on the forum use aviation gas (100 octane) for their small engines. I read today in a general aviation magazine that the FAA is going to phase out the current formulation by 2016.The reason? Not what you expect! It does contain lead and the EPA has concerns but the real reason is that their is only one maker of the lead additive in the world..and they"re considering discontinuning it as it is a very small market. Shell among others have been experimenting with other addititives and "think" they can get all the benefits of lead with other propietary formulas. It would retain the 100 octane rating. Thought you might like to know.
