The Jazz really likes town driving, the gearing makes for great mpg tootling about.

Ours is averaging 50.7mpg on the fibometer after servicing, a mixture of driving, I'm happy with that.

I find town driving allows the greatest scope for improving your mpg. With anticipation, turning the engine off at long lights, avoiding using my brakes, and trying to avoid the wheels actually stopping (keeping the car rolling can make quite a difference), I can make huge improvements. On the open road my mpg is no better than the next Jazz driver (unless he/she accelerates up behind traffic then brakes heavily).

Wow Jocko. Incredible MPG figures.

My average with this weather is about 57MPG.

The number below my avatar is my overall average, summer and winter, for the entire time I have owned the car. This is recorded on Spritmonitor.de and includes fill ups from before I started driving with economy in mind.

Well, you can't really moan about 57mpg.

After a few slightly longer runs, ours is hovering around 52.5mpg on the fibometer, the service and Pento HP oil certainly seems to have made a positive difference.

Filled my tank up this morning and my calculated mpg was 63.6 mpg, my second best ever. Both my ScanGauge (at 60.5 for the tank) and the on-board display (at 61.4 for the tank) were pessimistic. For the first time I used the Fuelly/peteo48 formula ( https://clubjazz.org/forum/index.php?topic=7808.msg61314#msg61314 Reply 170), and it gave me 33% urban miles and 67% interurban. Surprising, considering I always considered I did more urban driving, but probably fairly correct going on miles driven.
My ScanGauge data for the previous tank was:
Average mpg: 60.5 mpg
Max coolant temp: 84°C
Distance travelled: 488 miles
Maximum revs: 3544 rpm
Max speed: 68 mph
Average speed: 30 mph

Using premium petrol i got it upto 41.5mpg from 39mpg, just before my clutch died. Hopefully a new clutch will increase my mpg instead of wasting half the power.

That's about the improvement I saw when I tried Shell V-Power. Unfortunately, the extra cost didn't warrant using it on a regular basis.

With my nearly 16-year-old, Auto box Jazz (bought new) and with careful driving I'm still getting 60+mpg, with BP Ultimate fuel…Only 50-53mpg with standard fuel, so as the percentage economy increase is larger than the percentage extra cost for the petrol it's worth paying for.

Still an incredible, workhorse car. And the greenest car is the new/used replacement you DON'T buy (as they say) so I intend keeping it until it craps out!  ;D

Welcome. That is very good mpg figures. I only saw 2-3 mpg difference, and here the price difference was 10p+ a litre, so there was no contest.

Once again, a disappointing fill up at Morrisons. Apart from the fact that I was shopping there yesterday and didn't top up, then went in for petrol this morning and found it had gone up a penny a litre overnight! Lucky Friday the 13th.
What was disappointing was the fact that that my fibometer said 58.1 mpg for the tank, my ScanGauge said 59.8 mpg and my calculated figure was 53.2 mpg. That is roughly a 20% drop since my last top up, with almost identical drives and weather conditions.
As I said, disappointing.
I think I will try one of the less convenient to get to filling stations for a spell. See how it goes.

well my new clutch claimed i was getting 48mpg....for a few hours, then it crept back down to 41mpg. I've since changed the oil and had the final four spark plugs changed; and i'm still at 41mpg. I'm out if ideas to try and improve it.

Probably more to do with your driving habits, routes and anticipation than the car itself. I seldom ever use my brakes. In fact, unless I am approaching a downhill junction, I consider it a failure if I have to brake. As someone said elsewhere, "the brakes are for stopping and correcting errors".

The price difference is 10 pence per litre on the branded fuels. It's only 5 pence per litre on Tesco and Sainsbury's high octane brews. Have you ever considered trying the supermarket stuff? Just interested.

Very impressive figures btw.
