Just come back from a 3 hour journey to get ice creams. Normally its a good hour and half 60 miles round trip but todays sunshine found us finding excuses to just extend further and enjoy the drive. I've been using E10 petrol , so I thought I would try the E5 to see if there was any difference, and I couldn't tell any discernible difference whatsoever. If anything it used slightly more E5 fuel, but that could just be me, enjoying the country lanes more.
