Hi there-I have had a 3 door Focus on a 54 plate for about 18 months now -the fuel economy I always thought was quite poor,but since using Bio diesel it has gone even more downhill . If anyone can give me a clue about this I would be very grateful Filling up usually costs me about 40-45 quid-using normal diesel, this would usually give me about 300-350 miles depending if I was doing more motorway/dual carriageway driving. With the Bio diesel I am getting maybe 250 miles- I have no idea why the mileage is so low, my only guess is that the A/C is on constantly ,even though I never switch it on. As it is under warranty still I have taken it the dealer a few times as the throttle sometimes sticks in 1st,each time they fix it ,and a few weeks later it goes wrong again. If I drove like a maniac every day I could understand ;) but I am Family Man these days!I must be as its Saturday night. TIA
