10.17.1 The following classes shall be restricted to petrol having maximum characteristics not exceeding “Avgas or Unleaded FIM” as defined in Appendix E.

As far as I can see, this covers F4 & F5 and appendix E, unleaded allows for 10% Ethanol. In other words Buckets can now legally use Av gas or any of the common commercial fuels sold to the general public for use in motor cars and these can be conveniently found at your local service station.

Yes you can now legally fill the bike up on your way to the track with you'er local service stations best, most already do.

It looks to me like any advantage to be had from deleting 24.2.1 is more about common sense convenience and cost.

A performance advantage, I doubt it, but if there is a performance advantage to be found at the local pump, then its an advantage available to everyone.

For what its worth, Team ESE still intends using Av Gas.
