I'm getting 60.77mpg average over the last 3 tankfuls. Average over 1 year is 57.59mpg. Best (last tankful) is 64.63mpg. Almost all my driving is 15 mile commute to work, roughly 5 miles urban 30mph / 5 miles A road and 5 miles motorway. Keep speed down to 50mph on A roads and 55-60mph on motorway.
