Mine is behaving well as of late, in the luscious weather.
New record for me on Tuesday coming home from Loughborough.

Had the journey been longer it would have been much better as i came off the motorway with a solid instantaneous 71mpg, and having average 64mpg. A few traffic lights and some slower roads gave me the above average by home. Was v happy with that. All on ACC but no aircon needed as car was nice and cool.
Previous trip had been down to Worthing and back (150ish each leg). Disastrous trip down with tons of stop/start on the M25 after a vehicle fire and 90 mins of queuing saw 46.5mpg. Worthing to Rugby with some sticky traffic on the M25, aircon on the whole way home (3 hours) and ACC all the way on the motorway gave 55mpg. Oil temps over 100 for the entire of both journeys (anyone else find this in the warm weather?)
