Thanks for recommending Shell V Power fuel - I use it in my 1996 Cadillac Deville.
Great news. Thanks for the support. In the summer (generally 15C +) I get around 54 miles per UK gallon from a Fiat 500 1.2 petrol for the same reasons you describe. It runs much cleaner at low revs. Ford has always reckoned that on a 200 horsepower engine, a 99 Ron fuel like V-Power is good for an extra 25 horsepower. Of course, manufacturers dyno test and rate their engines on the best fuel, so running on 95Ron you actually get less than the stated power output.
