That is good to hear that Frans is not in a hurry to make a direct change. I still have about 10 liter of fthe old 16% uel and it seems the Netherlands and Belgium is forcing the new fuel because the new Nitromax is on its way. Also the upcoming EC40+ need to be run with the new fuel.
I will mix some methanol and castor oil to nitro less fuel to mix it up with my fuels to 13%, I have heard the Italians run 13.5% nitro that stays just within the maximum determined weight of gravity.
There is a high chance this year I will swap to OS, I am running my last Novarossi engines, thats why.
