V-Power was the only fuel I ever used in the Cossie - when out at the 'Ring, I used their super high octane stuff (I think it was 102 ron at the station in Adenau) - the engine seemed to love it
Now tho, I just use regular Shell in the 540i - again, I have a shell card - V-power club member too from my cossie owning days
In the escort - anything remotely diesel like that burns LOL
