I am sure some of you have this information, but for those who don't, may be of some interest.
I have scanned and reduced to a reasonable size, I think it is just legible.

Show me the figures!stuart_hedges wrote:I misread the topic as MP3 chart - I had no idea what the thread was going to be about!
My TZD Turbo Estate does rather worse than the chart suggests in town, but better at 75 - which is what I tend to use it for, so that's good. I have no intention of ever finding out what it achieves at a steady 56mph, life's too short!
Sounds about right, although that 32 must have hurtstuart_hedges wrote:Sorry, Jonathan, I don't keep precise figures - I just brim the tank every time I fill it and calculate the mpg over the last tank. As a general rule I manage around 44-45mpg, a bit better if I happen to have done a lot of motorway miles on that tank and a lot worse if I've done a lot of town driving. Lowest I;ve ever seen was 32 on a tank where I drove across London three times...
I'm pretty sure the older square port engines were a tad better on diesel. For a time the parents had two diesel BX estates, one square port, one round port, and the square port one was consistantly better on fuel with the same usage.toddao wrote:I think that I've got a pretty economical BX - the bloody thing does run on fumes. Being a relatively 'new' 1.9 n/a ( 40,000miles since 1985) I put in €35 ten days ago and I've covered almost 600 kms since then and it's on quarter - must be almost 60 to the gallon in Uk terms or 4.5 litres per 100km.
They were, mainly due to being 6hp less powerful. That's the reason that 1.9D 309's were so economic: They stuck with the square-port engine right up to 1992, and so always looked more economic than they would have been if they'd changed to the oval port engine.jonathan_dyane wrote:I'm pretty sure the older square port engines were a tad better on diesel.
That's quite exceptional, particular as the TXD didn't have the 'long range' tank. Wish I had the self control...MULLEY wrote:Yellow low fuel light is now permanantely on, reading 670 miles on odometer, quite good? Thats in the txd by the way.
I suspect this car must have the long range tank, otherwise that's over 75mpg average, which I don't believe is physically possible.jonathan_dyane wrote:That's quite exceptional, particular as the TXD didn't have the 'long range' tank.
