Iv'e got the opposite to geordie boy, my 94 auto normally does around 21 ish mpg,over the last three weeks or so i seem to have been filling up more than usual,seems i'm getting 16.5 mpg, now i know the first figure normally goes down slightly in the colder weather to about 19 - 20 mpg. no change of driving habits, same journey to & from work, brakes are not binding, tyre pressures 40psi no signs or smells of leaks, fuel filters done 14500k, what's going on ?
