Changing from avgas to ulp jab2200

"Several years ago, EPA legislation mandated the removal of Tetraethyl Lead (TEL) from motor fuel. The EPA granted a special-case reprieve for leaded aviation fuel as long as there is continued progress toward a suitable alternative. Any such alternative must, by definition, be less-toxic than the TEL it replaces, which has been a problem with replacement additives such as Methyl Tertiary Butyl Ether (MTBE). Currently, there is no suitable replacement.
Here are a few of the factors which are contributing to the prospect of the demise of 100LL, EPA reprieve notwithstanding:
(1) There is now only one factory in the world which produces TEL;
(2) Of the several hundred refineries in operation, there is only a very small number which produce 100LL;
(3) A production run of 100LL requires a subsequent purge of the refinery (very costly) before resuming production of unleaded motor fuel;
(4) The leaded avgas requires completely separate transportation and storage facilities;
(5) The volume of avgas production represents an extremely small portion of the gasoline marketplace.
Those, and other factors will, in all probability, cause significant price increases for 100LL. That will result in declining usage, leading to further reductions in capacity, leading to yet-higher prices. The likely result is that, eventually, oil companies will no longer view avgas as a viable product"
