V-Power racing isn't going to give you a power boost because of the 100ron rating. If anything, its just imaginary. Rather then using V-Power Racing just use 98ron fuel and you'll be fine. As for the ethanol eating away at your fuel lines, they're just rumours, unless you start using more then 20% in your fuel.

The reason why V-Power is out in NSW is because a few units at the refinary have died and the production of V-Power was ceased mid January. There was supposed to be a delivery 2 weeks ago but it was delayed and an eta hasn't been provided. However this does not affect the production of V-Power Racing.

Personally, i use Mobil 8000 petrol and i've been able to get around 480km-500km on a full tank, i barely ever hit v-tec, maybe once or twice a full tank.
