In normal use I used to get about 35mpg from a 1.3 and 22 from a 1.6. I'd do a brim to brim measurement and if you are lucky you might just find that the gauge is not all that accurate...
Good luck

So if we're expanding this out to other Lancias...

My first 8-valve integrale did 23 mpg on the run to work and back.  The best I ever saw was 28mpg pootling around the roads of Wales on holiday with the family on board; I was astounded since most of that was done in a third gear.  On a night road rally I work on 15 mpg to estimate how much fuel to put in.  One thing that's better than my old Fulvia is that it'll do a whole 150 mile event without needing filling up when my Fulvia always needed to stop at the petrol halt.

The worst I had in that car was less than 2mpg competing on an Autosolo.  It did about 4 miles at full chat which left 70 miles of petrol missing from the tank when compared against normal running.  It also ruined the front tyres rubbing the lettering away half way up the sidewalls (set at 40psi).  That was running a Power Boost fuel pressure regulator, not a part I'd recommend to anyone

My new integrale (still an 8-valve) started off at 22mpg but, with the fitting of a Stack Lambda gauge I've been able to adjust the fuel pressure down a bit and now get 24.5mpg which is a 10% improvement.  And it'll still do a sustained 130mph (not at 24.5mpg!!!) so the fuelling can't be wrong and there may be scope to improve that further.  When I've finished I'll measure the fuel pressure and let you know what it's set at.

The gauge could well be completely wrong, but that doesn't change the fact that I only get 80 miles from 12 litres.  You were getting 35mpg from your 1.3, so mine should be there or there abouts.  Perhaps I ought to take the upright piano off the roof rack when I drive around 

I'm only a little way off, and I'd been told that she was running a little rich - perhaps it had always been like that but I'd never noticed prior to petrol going over a pound a litre.

If one good thing comes from this thread, it'll be a useful matrix... just don't use my car as the basis for the 1.3 Fulvia data Sparehead

I am surprised nobody has suggested entering the Cotswold Economy Drive. Around 120 miles of varied country motoring where you can compare results. There are six places left. Latest entry is a Saab Sonnet.

hi Lima,

In my view it would be worth taking out a second mortgage & filling the tank, and comparing the results brim to brim. Otherwise you can't be precisely sure about how much fuel is used for a particular distance. If you are lucky you might find that the results are not too bad (or they coudl be terrible!)

Best wishes

Peter, I'd love to enter the CED but we're away this on holiday this year (again!) ... next year we'll go earlier or later and make sure we're there ... (even if we need a second mortage!)

[peterbaker]

Whoops. Try again!

Have a good holiday and lets hope we both get lots of sunshine

Just to add a bit more useless information. This year I have done four sprints in my road car, an Alfa 147 1.9 Turbo D with 150bhp instead of the Fulvia until I can rebuild my engine. On the road it does the usual diesel act of retunring over 45 mpg but on a sprint I got it down to 15mpg which compairs well with 2 mpg from a petrol engine. Handy having the electronic buttons to get the exact readings!
It was fun but not as satisfying to drive fast as the Fulvia but fitting the Q2 LSD to the torquey Alfa gave it grip in the tight wet corners and stopped the wild scrabbling.

Thank you Marky - I'll create a separate topic and everyone can contribute ... then I can compile a spreadsheet (which I'll pop back into the thread) ... watch this (cyber)space

How's the matrix coming along? It must be quite comprehensive by now Steve
