I doing a little test right now to see what's the best MPG my 200 FF can manage. So far, the trip computer is saying 32.5mpg, but in reality it's much better. This has been done over 1.5 weeks going to work and back, which consists of sitting in Reading traffic, M4 J12 > J14 to Hungerford (through roadworks). On the way back I go a country lane route and come out onto the A4, then onto A34 > M4 J13 and back to Reading. I've also done a fair few school runs too.
Some screen shots and I know many won't believe me
Have seen 35mpg indicated over a 40 miles run, but school runs and sitting in busy traffic drags this down over a longer distance.
Hoping for 420 odd miles from this tank, which is about 35 REAL mpg (not some trip computer fantasy). After that, I'll see how low I can get it
