Just filled up at my local Sainsbury's today, and was confronted with the new E10. Didn't think that was coming till September.
Anyway, performance seems to be the same, though I thought the fuel gauge dropped quicker. Also, I thought the Bird was running hotter than usual. Outside temp was only about 20 C, but the temp gauge was wavering just under HOT in town, which is more than usual.
This whole E10 is a load of b******s ( to use a Boris quote). All the hassle it brings is going to save less than 1% a year on CO2 emissions in this country.
