Since this contaminated petrol fiasco I have avoided the supermarket petrol and though this is early days seem to actually get quite a few more miles per gallon than usual. (Noticeably on longer journeys) Do (the supermarkets) water down the petrol or something like the slops go in the carling?
Anyone else noticed any difference? My brother has better mpg too and he drives an XJ6.
