I know Dave Colledge from Retro Ford (Corby), not the magazine, has recently had his Duratec mapped by Dave Walker and had his Emerald ECU upgraded to incorporate the new Switchable Map feature and he has a map for 95, 99 and this Bio-Petrol.
The Bio Petrol gave Dave C a decent lift in power over the other fuels but I thought it was somewhere near 106 RON, it was almost like a race fuel.
