That's interesting about your mpg findings poodle. As mine seems unchanged between shell, BP, tesco and sainsburys. And I'm fairly anal about mpg recording, got a spreadsheet and everything lol.
I would switch back to a better brand if there was likely to be an mpg increase. Don't suppose you can remember which was 2nd best for mpg as they no longer sell fuelsave?
