just replaced all the fluids in the freelander, gearbox,ird,engine,diff, replaced the air filter, all have made no difference to my fuel consumption, also replaced the plugs and now it hesitates slightly, are the plug gaps set correctly from the factory, as i didnt check them, and if they are incorrect would that burn more fuel as i am only getting around 40 miles to a tenner, sometimes less, i'm not heavy footed and i drive easy to see if i can gain more miles, also bought a new fuel filter, would this make much difference as i cant see myself keeping this with the mileage i am going to get, thanks
