Just a quick one... (im sure its got a loooong answer though!
I do a LOT of miles and i cannot guarantee the quality of fuel i use. I try to use Tesco 99 or V-power if i can, its its impossible for me to run it exclusively.
If i were to get stage 1 map on my Edition... would it be ok to run it 50/50 on 95RON when i have to and better fuel when i can choose?
