I bet mine is pretty much identical to yours over that period. Urban makes up most of my trips.

Now that I am solely a city driver my dashboard display for this tankful in my Mk 1 is showing 44.5 mpg. The good thing is, despite the drop in mpg I now get two months to a tankful instead of two tankfuls a week.

Just bought a 2011 Jazz 1.2 S
Filled up tank with e10 95 octane Petrol  from BP
Only done 130 Miles in it, but MPG is currently 47.8 according to Computer
##Update:filled up after 317.7Miles, with 32.15L 7.07Gallons calculated real 44.93mpg
Travel is mixed 20/80 town/country
I also try to drive quite light footed changing up when the green indicator comes on etc.
I'm tempted to use e5 98 octane petrol next fill up as I had good results with it in my last car. i.e. better MPG almost compensated for the higher price.

Are you using Supermarket petrol? My mpg deteriorated over time after using this on my old car and recovered after a few fill ups of Shell 95 Octane petrol (this was before E10 petrol was introduced).

Well it is winter.
My weekly shop used to be a 25 miles round trip: It is now a 3 mile round trip (new Aldi)
I used to travel 50 miles weekly to yoga. Now 30miles (new yoga teacher locally).
Start of beekeeping season so I travel 12 miles a week on narrow roads with passing spaces up and down hills and top speed 25-30mph.
Net effect is my weekly travel has reduced from c120 a week to c90.

My average fuel consumption is currently 37mpg. ( annual average 42.something over 10 years).

Perfectly normal.

I just got a 43mpg result from my first full tank on my 1.4 EX. That was calculated, not the dash readout (which said around 47mpg).
It was mostly motorway mileage (260 miles) with a small amount of town and 40mph road driving.
I used supermarket fuel with an octane booster additive in it.

I am averaging 52MPG on every whole tank during the school runs/shopping etc. The best stats I have managed is 58MPG on an 18mile town & b road journey, 61.8 MPG on a 70mile motorway journey.

2013 1.4 Si

Wow  :o Really!? I own SI not so long 51K miles.
And on a motorway yesterday doing 1.5h run i managed only 55.6mpg on E5 petrol. I do think all the time smtn is wrong with mine consumption wise... But mine doesn't have full history.  :(

Does your SI have k&n filter or "paper"!? I don't know what else could be wrong with mine... 😕

That is excellent mpg especially this early in the year.

2013 1.4 si.  78K.

I was getting an indicated 48 on a run - in reality 45mpg.

Just had the spark plugs changed + service.  Same run, indicated 59.8mpg, in reality 53mpg.

Surprised by this change. Suspect that it is largely down to the spark plugs change.

In this time of spiraling petrol prices, an 18% increase in economy is welcome.

The plugs must have been really ropey. I have changed my plugs at 50% over the recommended mileage and it made no difference to mpg. The warmer weather will probably have had a bigger impact.

Jocko, agree on the potential impact of ambient temperatures

I am running a 15 plate CVT 1.3 

 I use Shell E10 fuel,and have to drive like a butterfly with sore feet to get 50mph.


  mileage is 33K,

  I seem to remember my previous 61 plate car ,with flappy paddles was more economical,.

  what do you think?

With fuel prices being what they are at the moment, I've been driving with a bit more focus on economy. The fibometer on the last tank showed 61.6 over 304 miles. Actual mpg 55.95 !!  8) I'm well chuffed with that, given that it includes a fair bit of town work and I'm using cheapo Asda petrol.

That said though, just over 300 miles now costs £46.72. Ouch. I always used to work on £10 per 100 miles.....those days are sadly very much over.
