[murrawo]

hi,
george in crawley, high fuel cons...how to diagnose and fix?
't' reg profile, with 114k on the clock - i know, a lot!!
i think the cons is about 28-30 mpg - this is very poor.
i expected about 35-40 with the usage i am ''subjecting'' the car to.
mostly urban and country lanes with limit less than 60mph.
can you help or advise pls?
thanks in advance,
george.
ps any good garages for micras in crawley ? not the main dealer!!
