Hi anyone know what a bottle or half bottle of booster will do for a tank of 95ron Irish spec petrol
We can't get shell vpower or anything like it and power on mapping day is way down on where it could be

 

depends what brand you use, most of them are just a temporary fix though not a full time solution. if your getting the car mapped why not just get it mapped to run on the fuel you can get?

Not sure what its like down south but up north Topaz and Go super is pretty decent with Sainsburys lagging behind and BP at the bottom (on my own car anyway).

There was a good thread about it on scoobyireland:
