only recently inherited mums car, when I find some time, some photos and an egggnog to follow, but last three tanks have given following mpgs

Nissan Micra 1.3 GX

37.26 mpg
37.98 mpg
38.16 mpg

and its not sedentary driving either, plenty of aggressive acceleration thrown in, so not bad!! main tip i learnt from last fulltank, dont go crazy with the throttle when engine is cold - once its warmed up, which takes all of 3 mins, then by all means go nuts!!!
