After 9 months ownership my Mark 2 Jazz Si 1.4 bought with 10000 miles on the clock has done 50/50 city/long distance driving. Most of the city drives are very short. My overall mpg is 39.7, single fill up best 50.76, worst 31.68 (when I first had it).
I'll have to try harder to meet the 47.9 quoted on Honest John's Real MPG website
Try driving as if the brakes don't work. The primary avoidable waste of energy is that lost in braking so more anticipation of the need to slow down saves fuel because you ease off the accelerator sooner. However, those short urban trips are a fuel guzzler particularly if cold engine and made worse by cold weather simply as more fuel is pumped into the cylinders unitl the engine is up to working temperature.

I clock my mileage between red light coming on (usually always comes on with a range of 34 miles remaining) and when I fill up e.g. red light comes on - I fuel up right away, reset mileage counter and then clock mileage until red light next comes on.

Based on this I get around 35-40mpg taking into consideration miles driven, cost of fuel (pence per litre) and spend of fuel when I fill up. Car computer tells me that this same period is average of 43-45mpg so there is a clear discrepancy between actual and what the computer thinks.

My driving is very mixed but I predominantly drive with windows up, air con off and usually just myself in the car with no extra weight. I'd say 80% of my driving is city/town driving on small journeys less than 3 miles and I drive around 180 miles per week.

I done low miles trips to work 3 miles there and back few trips of 7 miles checked mpg since I had car in Feb 16, from my own calculations I have got and average of 36.5MPG with a low of 33.5 and high of 41MPG, my car ave mpg is about 3 higher than my calculated, car only just gone past 10000 miles on 15 plate, only average 356 miles a month since I purchased it 11 months old.

My previous Jazz Ishift Ave was 40mpg with ave of 412 miles a months just slightly better than the CVT, 44.4MPG was the best 33.3MPG the worst on the Ishift .

Our 2014 automatic has now covered 22000 miles at 49.3mpg. Mainly rural driving in the New Forest and trips to major urban centres like Southampton and Bournemouth. No long trips these days.

Interesting week on the mpg front. Had a UK holiday and drove from the North West to Cornwall via The Malvern Hills. We did quite a bit of driving - 960 miles to be exact. 3 tankfuls (just did the last one today).

1) This one - about 311 miles - involved the trip down to Malvern and some local driving about then the continuation to Cornwall. Average speed around 45 mph and an mpg of just on 47 mpg. Quite disappointed but I had forgotten how hilly that A30 running through Cornwall is. There was also torrential rain at times. When I could I drove at 70.

2) The second tank included quite a bit of driving round Cornwall. A roads, B roads, narrow country lanes and the first part of our journey home (via Bath where we stayed one night). Better this time at 49.3. Ave speed 41 mph

3) Filled up today and this includes most of our journey home - mainly motorway with a few country lanes on the way to our overnight stop in Bath. 53.2 which I was happy with. I took a decision to cruise at around 60 ish - basically at the speed of the faster trucks but blipping up to 70 or 75 to get past clusters of vehicles.

Last time I did this type of driving I was in a diesel VW Golf (1.9tdi) which I would expect to get well over 60 mpg cruising at 70. Clearly the little petrol engine in the Jazz has to work much harder and 70 mph on the motorway might result in relatively disappointing mpg. At 60 ish on a longer journey, well over 50 mpg is easily achievable.

I find motorway driving returns disappointing mpg. I found the best bet is to sit in behind a truck doing 55 - 60 mph (not too close - those bars on the back are rather solid) and take advantage of him pushing the air aside. 55 - 60 seems to be best for mpg as well and sitting behind the truck doesn't p** off other motorists, as you might do on your own.

45.5 mpg (calculated) averaged over 51000 miles.
The display offers an optimistic 50.6.

38-42mpg, mostly town driving and used by learners. Only 260-270 per tank! But today up to 289! The garage tells me 350! But never really got there. Best tank full was 303.

Iím attempting to see how far I can take Hypermiling in a budget.

I commute 150 miles a day so good mpg is a big deal for me.

I have an 09 1.4 ex

Iím logging all my mpg for each journey.

The first week of driving in a normal manor returned an MPG of approx 48.

Ive recently removed the rear seats, ariel stalk, rear seatbelts and boot tray, anything that doesnít need to be there is gone. And I only keep half a tank of fuel.
So far Iíve run about 58 Mpg avg. with the highest run at 60.0 mpg

It should be good for some better results when itís nit so cold and Iím not battling wit snow etc!

Looking to have the car lowered in the next month, and the panel filter is desperately in need of changing.

Iíd really like to swap out the oem 16Ē alloys for the 15Ē ones but I canít afford to buy unless someone here fancies a direct swap!? 😀

To be continued ...

Just to add the the starting weight of the Jazz was 1100kg

I have her down to approx 1063kg and aiming to get more out!

Iíd like to be under a Tonne but thatís unlikly!


EDIT: To add that Iíve just been down to have her weighed again and sheís down to 1040kg! Pretty happy with that, under a tonne might not be impossible!

How much do you weigh?

Do you use EOC?

69kg, so around 1109kg with me in it. (The curb weight being aboht 1119kg I think)

I use P&G which is pretty effective as I have to climb over the penines to work. Reducing the weight helps me climb it (although it does marginally reduce the distance I can glide)

EOC is that similar or does that require turning the engine off? Um...maybe I donít understand but wouldnít the steering lock turn you into firey death pretty quick!😀
