Shell has developed unleaded 100-octane fuel to replace 100LL

Shell Oil announced that is has developed an unleaded 100-octane piston engine fuel to replace 100LL.  Presumably, the fuel will enter the FAA’s recently established fuel testing and certification process. Shell said the fuel is a culmination of 10 years in R&D and initial testing has been done with two OEMs, Lycoming and Piper. None of the companies offered any information on what the new fuel might cost.
