Another question on fuel. I was told when filling up with fuel and the pump cuts out when it is full, not to be tempted to put more in as this goes into a reserve tank. Previously with my old car, my TT I would keep pulling trigger until the pump cuts out every fraction of second, which would be when the fuel would put at the top of the tank touching the nozzle.
So, my question is how are you meant to fill up. Have Audi told me porkies, or not? To answer the original question I alternate between Shell V-Power & regular mainly doing 3/1, but I'll now change to only V-Power. Also, only 2x Shell garages in my area until recently, & I have never been near any of them when I need to refill.... Typical!
