I think some people might get 50 but if you go on Fuelly.com and look at other Jazzes you won't find many average more than the low 40s. Some much lower than that.

I've never got 50 even on a long run.

It's not an especially economical car but, as a package, it suits me.

Yep,  realising that now.

I think 45mpg may be optimistic for me.

As you say , as a package its good at what it does.
Lifes too short !

As my previous post, now done 17000 from new at an average of 54.3 mpg for those 17000 miles. Last 1200 miles average 53.3. It can be done !

Is yours a CVT bill? They do do a bit more mpg according to the figures. Also, are you using the computer or brim to brim to measure?

And what's your secret? I must admit I am reasonably happy with just over 40 because I do so much stop start stuff but the most I've got on a long journey is 48.9 and I wasn't caning it.

Winter is not a good time of year to get good fuel consumption. Apart from the basic problem of the engine taking time to warm up (I always wonder why car manufacturers don't provide thermostatically controlled louvres on the air inlet to the engine compartment), cold air has higher viscosity (= more drag), it's often windy (and tail winds don't compensate for head winds) plus there is usually more demand from the electrics.

A couple of my fuel saving tips would be (a) keep the revs below about 2,000 unless needing the power and (b) drive as if the brakes didn't work and try to anticipate needing to use them by easing off the accelerator a bit sooner.

As above + drive at 60-70 instead of 70-80mph, although I do that because I'm paranoid that mine will be the first Jazz caught speeding at 75 mph !

When I first got the car , which is manual by the way, I used the brim to brim (oo-er missus!) method once, found it was roughly what the computer said, and got a life and trusted the computer. If it's 5-10 % optimistic I'm still happy with my fuel consumption.

Oh, and the other trick is to tape a raw egg to my accelerator pedal and try and finish the journey without breaking it . ;)

I forgot (being an old duffer), my best fuel consumption was Billericay to Portsmouth , about 120 miles, mainly motorway, when there was about 10 miles of 50 limit due to roadworks, by the time I got to Portsmouth the computer said 59.9 mpg. for the journey. I can live with that.

Good stuff bill. Even if you knock 10% of for computer error you are near 50 mpg overall.

I've got a period coming up when I'll be doing 70 miles a day, mostly motorway, for 4 weeks. I shall be watching the mpg closely to see if I can crash though the 50 mpg barrier if only once.

Hi everybody, I make a 60 mile round trip to my mums each week, I set off with a full to brim tank, refill when I
get back, it takes a fiver which is about 5 litres, 1 gallon is 5.1 litres so that's about 60 mpg (mixed driving conditions)

Charlie, you may like to revise your calculations,I believe one gallon is 4.54 litres which, I think, works out at 55mpg.
Still very good though.

All my Jazz's fuel computers have been optimistic by about 2mpg so roughly 4%.
That's close enough as far as I am concerned for day to day comparisons.
My Mk 1 CVT's returned about 48mpg on average, my Mk 2 manual about the same.My current car is a Mk2 facelift CVT 2011 model that is returning about 50mpg but the CVT's have always had higher overall gearing than the manuals.

I had to use an online conversion tool as i only know liter/100 kilometer. ;)
Our Jazz computer 'says' 6/100 what is 47mpg. Now it is cold when i step in the car and i use climate control plus extra blowing front window and back window/mirrors until it's warm and clean. Before the cold it was 5.8/100, which is 49mpg.
Mostly short town driving and the numbers are without correction to real usage -- it is just what computer shows me. ;)

Hi Guys

My 2013 Ex CVT has now covered 19662 miles and the main trip is showing 45.9 mpg.
However the 'A' trip is showing 7552 miles and is showing the same mpg, so I must have reset the trip at some point, so not really sure which mileage the result relates to
The best recorded result so far has been 57.7 mpg over a 240 mile return motorway run, from Solihull to North Lincolnshire, driving at around 60-65 mph.  This is a fairly regular trip and I can usually repeat the result, within perhaps 1 or 2 mpg. All results from the trip computer.

Best regards to all.

We have a 14 plate CVT. Managed to get 66.2 mpg (computer) on a 40 mile run (Croydon to Hornchurch).
