It will over-read by about 10% as do virtually all speedos. That's to make sure they satisfy the c & u regs that say they must not under-read, and they have to allow for wear and tear of tyres etc.

Well i have had my car for about a fortnight, and to behonest, I am loving it, although it does have some idiosyncrasies that I am notused to after my Scenic, but these are out-weighed with having air-conditioninglol.

The only thing I wasn't too happy about was I took it for its first real tripdown the motorway, and after working it out I averaged a mere 47.5mpg, travellingmore or less the speed limit(ish)... and in my Scenic I was usually up aroundthe mid 50's.. I suppose there are always compromises to what I am starting tosee as a better car.

Is there anything that can be done to help my fueleconomy, other than slowing down :$

If it's a brand new car it will improve A LOT come time and more miles. Our previous Roomster was improving its MPG with every tank up until 20 000 miles driven or so. Also if you generally drive on very low revs diesels tend to clog up, so assuming the run in period is over, drive it a few minutes in high revs and it will feel like a new car. Just make sure the engine and oil is up to running temperature before to avoid any unnecessary wear.

When you say high revs, is that over 4k?

Yep! I was running almost up to red line in hard acceleration, then driving a couple of miles with ~4K RPMs. (I do happen to have a convenient stretch of highway next to me so this was easy). A few times during the drive I was flooring the pedal and accelerating up close to the red line. Then some slow driving before turning the engine off again to let the turbo cool down.

This in no way scientificly proved, but at least in my opinion I could see a clear improvement in MPG after such a "cleaning run". Also the particle test at the MOT was passed without any problems so I was obvuoisly doing something right.

I'd be intrigued to know what speed you'd be doing at 4000 rpm in a diesel engined Skoda.

Not much more than at 3500rpm! It seems to tail off at that level... Really there's no need to go above 3000rpm with the 1.4TDi... Keep it between 1500 and 2500 for best economy...

That means I can't go as fast as I wat to :( lol

Around 90 km/h in third gear if I remember correctly!

I was using a 1.9 TDI, but I guess the diesels behave similarly in this respect. I was not saying that the car delivers more power in the high revs, my point was that by occasionally revving and stressing the engine a bit it cleans and runs better and more economical on the lower revs for some time.

'course you can, but what's the point? If you want to rev the nuts off an engine then buy a small Italian petrol car, not a small Skoda diesel!!

I couldn't afford the insurance on a small italian
