Could be the change in the weather. I assume you have checked the tyre pressures?

I was going to do that this afternoon, but it's piddling it down... and I seem to have misplaced the pressure gauge. I'll have a look tomorrow, other half would happily drive around on four flat tyres.

I was going to do mine too, but it was pretty miserable. I'll wait for a nice dry, sunny morning.

I took it out for a good run, I very rarely drive it. I think we have a binding offside front brake. It's not bad, but the disc is noticeably warmer than the other side. Can't find anything else wrong, so will have to start with that.

Can't get mpg above 44 on the fibometer, usually over 51.

Sounds like that could be your problem. One of the benefits of regularly tracking your mpg is you soon know when something is off.

I have started a spreadsheet and using the clock (odo) reading and how much petrol I fill up at the petrol station, I average around 42.5 MPG. The sort of driving I do is a mixture of motorway, main road and local roads.

Knock 10 mph off your motorway speed, check your tyre pressures every week, anticipate instead of braking where possible. See what that does to your mpg.

Just want to share that did a few upgrades on my Jazz CVT 1.3 and now doing 48-55mpg instead of 34-42mpg before.
1. Changed new front tyres (toyo proxes cf2).
2. Start adding Redex fuel additive.
3. Switched from Morrisons fuel so Sainsbury's fuel.
4. Started use engine braking with paddle shifters.

Done the same over time. 1 and 4 made a difference, 2 and 3 had little effect.

Wouldn't engine braking using the paddles in the CVT add undue wear on the gearbox?

How does the onboard computer fuel economy thing work?

I reset the odometer about a 100km ago and have been driving sedately since and it pretty much continuously says 8L/100km average fuel economy.

Someone mentioned somewhere that the average is linked to how far back you reset the odometer, the shorter the time the more responsive it is.

Don't see how. No difference in accelerating or engine braking forces on the CVT, the steel belt is a push type.

I just reset the "Fibometer" at top-up time, then disregard it from then on (I cannot easily see it as my ScanGauge E sits in front of it). Reading L/100km doesn't make for a very accurate display. Yours says 8L/100km whereas mine says 62.4 mpg. A tiny change on mine is displayed.
Best thing is just to do the calculations at top up time. Use Fuelly.com or the like.

I'm assuming not more wear than acceleration but still wear none the less?

Much cheaper to replace brake pads than eventually opening the gearbox.

I do use fuelly but I was just wondering if the average shown by the onboard computer is typically pretty far off?

The onboard instantaneous economy meter seems to show 5L/100km when I expect it to.
