And which 95 were you using, just remember not all 95's are 95's...

And your feel economy will almost always improe when you reset ecu. The only way or you to do a proper comparison is on a racetrack or provig ground with identical cars.
Shell E10, which according to the pump is 94 RON, and Shell 95.

I did run through 3 or 4 full tanks, and noticed no difference between any of them. After the final tank I got a figure which was 0.03L/100km less than what I initially got on E10, which is probably nothing to do with the fuel anyway, and simply because the driving conditions can never be 100% identical.
