Also (geek warning, sorry I have powertrain development qualifications) a 1600cc Sigma petrol (1.6 zetec s, focus, mondeo etc) has a compressed chamber volume of about 35cc. 450cc of petrol in 2 revs (1 engine cycle) is 112.5cc of fuel per cylinder, it would lock solid. And diesels have compressed volumes of as low as 10cc in some cases. Sorry nerd off over.

Long story short, duff statistic mate
The actual figure is most likely out, but it is certainly true that a cold start uses more fuel, but no it won't affect the fuel gauge lol, that will be the shonky instrumentation!
