When I do a tank full, I get around 400 miles from. 1.3 at 40/45mpg
Depends on what your doing short comutes kills mpg, as does stop start cold starts ,and ragging it
My fuel gauge is weird, and get about 70miles on £10 or 8ish litres ,not exactly a slow or the generalist driver
GOt a ga16 airbox, j&r filter, 185/60/14 conti eco tyres and added weight off options
