I've spent 3 weeks driving a brand new 2012 Kia Picanto 2 Ecodynamics 1.25L car. Supposed to be 65mpg ... By my calculation I think that's around 43mpg.

Brim to brim calculations are the most accurate way to measure mpg.
clangnuts is right - I drove over 700 miles on a tank once last year, low fuel light came on, did another 50 miles , indicated range dropped to 0, did another 15 miles, finally got some diesel (previous garage was empty!) and I still had 3 litres left in the tank. Wouldn't recommend it though :eek:

Well, first set of figures in. Managed 414 miles on £50 worth of fuel.
Filled it to the brim. According to the iPad app, the mpg is 44 mpg. This will increase as more readings are input and it gets more accurate.

This is a misleading headline written, I guess, by a journalist looking for attention on a slow news day.
The figures are 100% accurate - they're tested under laboratory conditions, for the same 2 driving patterns, for all cars.
Then school run mum comes on saying she sits at traffic lights and start-stops and has used up 1/4 of a tank and the computer only says 20mpg?
Who do you believe?
Everyone has different driving patterns, plenty of people don't even have a pattern.
In your current car, if it's in good condition, and the official figures say a combined 30 mpg, and you get 20, then it's safe to assume that for your driving pattern, you can knock 1/3 off ALL combined figures for ALL cars. Then you won't be so disappointed with your next car.
I know, for example that I can just about get the combined figure with my driving pattern, and that's what I have done in my last few cars. Longer runs, or 'enthusiastic' runs will affect this of course, but if you're not calculating your MPG properly (brim to brim as above) then don't bother posting about your MPG as it's probably inaccurate.

Not recommended in Diesels because if they get too low or you run out they need re- priming once you have turned them off. AT best it will be endless churning on the starter motor at worst doing it manually.
I knew about it but had no choice once due to fuel shortages. Limped into a service station OK but sat red faced at the pump, after filling, as I tried to coax a new Vectra into life.
