Whatever the PCM is, I must have upset it, as today a miracle has happened. On a 30 mile journey to birmingham, at 70mph on the motorway, it gave 45.4 to the gallon. On the return journey, at 58mph in cruise control, an astounding 53.7 to the gallon. The Ford God must have heard my plea. Lets hope this good fuel consumption continues. will save me a fortune.
