Done 43K in my Mjet trip computer showing about 60mpg though when I checked it brim to brim over a number of fills it was 5% optomistic I run mostly on fast A roads now which hammers the mpg I was getting 65+ on bimbley slow roads littered with retired folk wearing hats. Driving at night lights on seems to affect it by 2-3mpg. Anyone got any info on good fuel or remapping ? any info would be appreciated.
There's Econotune for the remaps:
