Well Guys, I took the plunge and added 10% methanol to 10 litres of bio (I assumed there was 10 litres still left in the tank) in my Citroen Dispatch van. It's 2006, d4w engine, non turbo and is gutless, as they all are.
Now I know it's a bit pointless making statements without any data to back it up, but it 'seems' to be a totally different animal, much better power and acceleration.
