I was getting near empty so went down to the local garage and OMG!!!! No V-Power
Had to pop to Tesco's and put some Momentum 99 in, so not a happy bunny, but it was cheaper and better than putting 95ron in.
I guess the 75 litres of Methanol will help if I get desperate. I can add 16% methanol into the tank to 95 ron to get 105 ron, but I don't really want to go there!!!
