Did a 200 mile round trip at the weekend (Saturday) and noticed that my mpg was considerably higher than during the normal commute to work at the moment. The only difference was that the ambient temps were noticably higher than of late....up to 14 degrees rather than the usual 7 or 8. It confirmed to me what the cause is for certain.

Mine's hit 57mpg going a 50 mile round trip per day. Incidently, air filter renewal every 40k? Are you serious? My old Pug needed one every 6k! I wonder if mine's had a new one yet then, I only just bought it on 40.5k.

Try changing the air filter more frequently. It is so easy that I can try train my dog to do it. I change mine every 8-9k miles.

mines suddenly started drinking fuel aswel!!!....the last three fills are only getting me 450 KM!!.....the last two i have driven like a granny (staying under 2k rpm) trying to improve it but no joy!!!:( .....i was getting those figures in my octy RS and i was booting that!!!:(

Well I do not how you guys get a above 50mpg

I have never achived 45mpg, dealers say that it because it has only done 20k, I think that there may be more there than meets the eye!

Mine is now on 5500 miles so that statement from the dealers is crap. Although it is true economy will increase as engine wears in. Drove from Bristol to Weymouth and back (220 miles) which is a combo of m/way & a/b roads. Achieved avg 58.9mpg. That included a few foot-to-floor overtakes and 80-90 on motorway. Normally I get 40-45, but that is short trips and spirited runs.

Beats the cr4p out of my previous V6 Mondeo's economy - 28mpg from 100 miles @ 40mph!

Winter diesel and the damp air will make it marginally harder for the engine to breath through the air filter. If this is already full of cr*p then the economy will suffer.

I'm the same at the moment, I guess it is the cold weather cos I got 334 miles out of my tank which lasted me two weeks, and my miles per gallon over one week was 36.3mpg.

I find changing up at 2000rpm instead of 2500rpm on my 9 mile commute to work increases the (indicated) effciency by about 6-8mpg. Previously I've been getting 360-380miles from a tank but I'm on course for about 420-440miles this tank after changing up early.

Top tip

63.4 MPG on way home tonight (26 miles approx). Last owner had the air filter replaced last April at 36k and I'm on 40.5k. Looks like he did about 7-8k per year in the service record, I'm going to be looking at 12k+.

Incidentally last owner left a little MPG note in the back of the wallet. Looks like 58-60MPG was quite normal. I shall have to print a small document out for me to continue with.
