It's not indicated mpg at all, some of us actually work it out!!
The indicated MPG is up to + or - 2, it's very rarely bang on in the Focus I find. Was more accurate in the Golf, less accurate in the Vectra, interestingly.
Marketting purposes may like high numbers...but it's pointless when people KNOW the numbers will be wrong now... No-one believes their stated MPG figures any more. I don't even bother looking at them now, much more accurate to ask on a forum and get a rough average...
