Having returned from our Scotland jaunt, I note two things: This is the first long trip (1500 miles) I have done with the car fuelled entirely with E5, and secondly my average fuel consumption over the distance was 40 mpg, as opposed to the 37mpg or so I had consistently got in previous years.
So either E5 isn't as bad consumption-wise as I was led to believe, or I haven't been giving it as much beans as I used to. The first 1250 miles were all top-down, but the last 250 miles I did with the roof up as it was straight down the M6/M5, there were periodic heavy showers, and quite frankly I fancied a more peaceful drive with less wind buffeting. The consumption for that leg was 42mpg, the car is clearly a bit more aerodynamic with the roof up.
Oh, and fuel in the West Highlands is no more expensive than in Gloucestershire. 205.9p/litre.
