Birch Performance think: The perfect pour in fuel for those who demand a high quality of fuel but don't have a specific race fuel tune. The lower oxygen content of this 106 Ron unleaded has minimal impact on your AFR and fuelling, whilst still packing a punch. Perfect for a bit of fun whilst providing extra engine protection when pushing hard at events.
