I used BP 97RON for a month and then BP 95RON for a month and my MPG has been higher with the 95RON.
Being as Tesco's have been running a promotion with 3p off a litre for the last 2 weeks I have been filling up with that and my MPG is still rising.
I'm thinking that my engine is loosening up (only done 2,000 miles) and once the Tesco promotion has ended I'm going back to 97RON for a while to see if my MPG rises.
As far as performance goes I have not noticed any difference, but I don't thrash it anyway.
