Sainsbury's fuel is the reason I don't use supermarket fuel. I used it twice on my Megane and it knocked out one of the four injectors each time. I find that Shell is the best for the Megane, using the ulimate unleaded I have achieved 56mpg out of my Megane on a 120 mile run. I don't think the Focus could ever achieve that even if I pushed it down a hill :lol: .



This is interesting as My Focus 1.6 1999 at 76,000 used to give more MPG on Sainsburys. The cam belt went (nothing to do with sainsburys) and I had an engine swap for a newer Zetet 1.6 with only 33,000. Ever since I have driven it the fuel consumption is definatley poorer. Same engine cc , same car but not as efficient. I have even resorted to turning off the engine at lights now. It's a lovely car and very comfortable but how I miss the cheap running of my Peugeot 106.

Turning off the engine will have an adverse effect. Huge amounts of fuel are used to start and engine compared to nigh on nothing to keep it ticking over. Make sure your windscreen blowers arent on full demist if you have air con fitted as it will use air con to clear the windscreen quicker even though the little light isnt lit on the air con button. For a car with a 30mpg average text book, I dont think 28mpg average is poor at all this time of year. Engines love cold air. More cold air means more fuel used. Summer makes cars more economical. Mine pulls like a train this time of year and the mpg falls from 45mpg running around to about 42mpg. But in summer its back to normal.

Aircon is a useful tool in the cold, as it draws moisture out of the air. Most people associate aircon with being cool, but it's a very quick way of getting your car up to a comfortable temperature this time of year.

Granted, it affects economy a little, but it's more useful than not :)

gotta be honest 28mpg youre getting and its stated as 30.1mpg nowt to grumble about its pretty decent strange that my mk1 1.8 zetec has better mpg than a newer smallewr engine though

Well 30.1mpg is the minimum stated cold consumption on the urban cycle combined is meant to be 40.9 mpg and extra urban is stated as 51.4mpg see: http://www.vcacarfue...ils.asp?id=7027

thats what i found remember it isnt the reg but the build date of the car it may be an 04 but it can have been built a fair bit prior to that so it very well could be the older engine in the car

http://www.etis.ford...eRegSelector.do

go here enter the reg and youll get the details you need

also if you read the info on the link you had its tested in a lab at temps of 20-30 degrees max speed 31mph minimum 12mph for 2.5 miles thats not real world figures we dont drive in temp controlled labs at those speeds for a mere 2.5 miles it does not acvcount for minus5 conditions or the fact that with the temp outside the car is running cooler taking longer to heat up or that you are using rear demisters front heaters lights etc or that the car is burning more fuel to do this it also doesnt take into account driving styles no offence but some women brake too late too much and accelerate too hard men too not just women.

take the car for a run a good 15 mile should do it when you get home leave it running and get out sniff the exhaust if its burning too muvch fuel youll smell it also check the plugs if they are normal then the engines running as it should not over fuelling or running too hot/cold

That is a extremely useful link thanks mine was a 2005 car I just entered 2004 on the VCA site so it doesn't show the MkII by mistake. The build date though on the etis website states 04.11.2004.

I used the Focus last night as my wife has been using mine in the snow and ice. When it started at first all I could smell was unburnt fuel for 2-3 minutes and the idle was quite high but then it settled down so I think it is struggling with the minus temperatures as you say. It also has the heated front windscreen I'm not sure if this is standard or not but could be putting extra strain on the engine. I'm going to do a 2 week swap in a week or so with my wife and see what I can get out of it on my daily 36 mile commute.

I will check the plugs when the weather is a bit better, as I don't have a garage and the prospect of being under the bonnet of a car in this weather is far too depressing.

Just a quick update on the last tank of fuel the Focus returned only 26mpg which is now well off the urban figures and even taking into account the cold weather I think this is still pretty poor. I tried removing the spark plugs and they won't budge at all. Which is also concerning so I have left them for now as I don't want to damage the Aluminium head.

I have swapped cars with the wife so I now have the Focus to give it some long motorway runs. There is a part at the end on my journey that just is pottering around the uni campus mostly down hill so I usually dip the clutch in gear and freewheel I have noticed that the Focus unlike my Megane doesn't speed it it feels like it is going to then slows slighty. Could this be the brakes binding? it would certainly explain the poor economy.

Also should I be worried about not being able to lossen the spark plugs? I was using all the force I could muster but it was just a Halfords spark plug tool with very little leverage.

Thanks

Hi, have you recently purchased the Focus? If so like me [I bought mid October] your experiencing winter consumption. I also was disappointed with the fuel consumption, coming from a 2.0lr turbo diesel. Mostly knocking around town on 2 mile journeys at peak time and queuing in traffic. With the odd 13 mile round trip to the next village once a week. Returning on the last "brimmed" tank reading 28.06mpg [manual says 32.5mpg] The last two brimmed tank readings prove the trip reading to be accurate to 0.1 or 0.2 of a mile. So considering it is winter conditions, and the journeys undertaken, maybe it is not that bad after all.

I say this because immediately after my last brim tank visit to the petrol station, last Saturday. After resetting the trip meter, I set off on an evening 31 mile round trip on A roads. I had an adult passenger on board, with a full tank of petrol weighing us down. We did not experience any major traffic hold ups, though we had to negotiate three sets of traffic lights in a town on route. It was below freezing, verging on damp and fog, so was running with AC, heater, and lights. I was doing mainly between the mid fifties to sixty on the open road, with the trip meter at end of journey recording an average speed of 34 mph. And it recorded that the journey had returned 42.7 mpg. So I reckon that its not so bad after all, waiting to see what some sizeable mixed tour driving returns in the spring and summer months

PS: the spark plugs removal, have you tried slipping a bit of tubing over the tool handle, thus giving you more leverage?

diesels are quite frankly rubbish in town driving and dont give good economy petrols are better in town but on long hauls the diesel will show its economy

Thanks all for you advice, but I think it is due to binding brakes I jacked it up today and there is alot of friction when turning the wheel the inside pads and worn right through and the caliper piston appears to be sticking. So that would explain the fuel consumption issues it has its MOT tomorow and so will undoutably fail the nearside lower torsion arm bush is shredded as well. oit will fail in style.

I let you know how much the consumption improves by when the brakes are sorted.

to check the brakes jack the car up and the wheel should spin freely if not the brakes are binding you may have water ingress through the washer jets which has corroded the spark plugs in those halford tools are useless a decent socket for it and a ratchet is best also free wheeling damages the engine and doesnt save fuel sounds like the pistons need to be cleaned and greased with coipper grease and worked back and forth to free them up the excessive heat would have warped the disks so ide change these and the pads and check that the heat hasnt effected the wheel bearing

If it's going to fail it's MOT why waste the 50 having it done. I had front disks and pads fitted by an indy on a T reg 1.8 Zetec back in Dec 08 for 100 [in the hand]

copper grease on a caliper piston? eek! that will scratch the bore to f$ck and it will damage the seals.
when rebuilding calipers, you use brake fluid to lubricate the piston back into the caliper? surely you would do the same to free it up?...

behind the rubber seal of the piston it should be copper grease in there i didnt describe it well not the actuakl pistio n i push the piston out qa good inch or so and gently lift the rubber seal up then using a syringe pump some copper grease inside refit the seal compress the piston back then out again then back clean up any residue it doesnt damage the seals half youre brakes are lubricated with copper grease
