Diminishing MPG
I got my Touring Sports 1.8 in April. Right through until September I was getting a steady average mpg of 68. Recently I'm struggling to beat 63 with no change in driving conditions. I'm wondering if anyone has similar experience? I would have expected it to improve as the engine runs in. I've done 6500 miles so far. I'm not sure if Toyota would recognise it as a guarantee issue.
That's what they say, for the slightly excessively named Esso Synergy Supreme+ 99 E5, at any rate!

Apparently it does depend on where you are tho', Scotland and 'The North' as well as Cornwall for some reason are still ethanol'd
