Right, so these are my figures for my 1.7 CDTI FWDafter my first full tank of fuel.

Diesel price was £1.39 ltr on both occasions.
On the 24<SUP>th</SUP> January I filled up with Diesel with 166 miles on the clock.
Filled up with 46.27 Ltr (10.2 Gal)
Costing £63.34
I then did another 402 miles and filled up again on 29<SUP>th</SUP> January
Filled up with 49.47 Ltr (10.9 Gal)
Costing £67.72
As you can see I put in aboutthree quarters ofa gallon more on the most recent filling howeverthe needle before filling was actually slightly higher than on the first filling!!! The difference I would estimate to be 20-30 miles which would then coincide with the DCI reading of 44mpg give or take.
According to this and the estimated difference because of the apparent discrepancy in the amount of fuel that was put in it would seem that I have only got 41mpg which I am not very impressed with considering the published combined figure of 62.8mpg or even the lowest figure for Urban which is still 52.3mpg!!!
I know that this will get slightly better as the engine beds in and I have still reduced my cost per mile from my previous car which was 20ppm to 14.6ppm which even with this starting and hopefully lower consumption figure saves me £2.70 per day just getting to work (50 mile round trip) which is also £675 per year using 250 days per year.
Due to the above I can therefore estimate that the red line is just under a gallon so I will have approx 40-50 miles when the gauge gets to the red.
Look forward to seeing what the next tanks gives!!
