Just read through previous thread about not getting the right mpg. I put 20 quid in the car yesterday and it showed just over 3/4 of a tank full. Only driven about 30 mile since yesterday and now i showing just over half a tank. Wondered if it was the guage but dont seem to be and wondered if it might be a cracked breather pipe. But does anyone know where i should be lloking for this as i don't have much of an idea? Cheers
