However, doing the same route a the same speeds since my first oil change and putting the pirreli run flat tyres on the front, (still got decent dunlops on the back) that my miles now average about 235 per tank...

This is now costing me a fortune and im considering taking it back to be checked over, but has anybody else noticed this with the pirelli tyres or even the firs oil change? I would expect it to be more efficient!

Thanks
Mike

I have 3 Dunlop RF's and One (odd) Pirelli Euphoria RF. I had an oil change 13000 miles ago and it didnt make any difference (or at least any noticeable distance) to my fuel economy
