    Is there an issue with the fuel tank in my 2008 Ford Focus?

    Ford Ford Advice Ford Focus Ford Focus Advice Ford Focus 2008

    I recently picked up a 2008 Ford Focus manual hatch through a private sale, and I'm worried there is an issue with my fuel tank. Firstly. I can't seem to fill it more than three-quarters (around the 30-litre mark) yet the specs say the capacity is 55 litres.

    Secondly, 20 litres just got me through 140kms despite online info saying average city driving is about 9.3 litres per 100kms. Is this cause for concern?

    I'd say you're looking at two different problems here, neither one of which involves the actual fuel tank (which is, indeed, 55 litres). The first problem is more likely to be the calibration of your fuel gauge that is out. If the gauge isn't reading accurately, it will tell you the tank is emptier (or fuller) than it really is. Your car is actually doing what most fuel gauges do, which is to be a bit pessimistic, suggesting there's not as much fuel still in the tank as there really is. You could have the gauge recalibrated, or simply know that even when the needle is at empty, you've still got a buffer zone of fuel remaining.

    The fuel consumption, meanwhile, is another issue and it's true to say that 20 litres for 140km of driving is too thirsty. A basic tune up might help, starting with fuel filters, air cleaners and spark plugs. But don't ignore things like correct tyres pressures and whether there's a roof rack fitted; these things will affect fuel economy more than you might imagine. And never under-estimate the affect driving style has on fuel use. A driver who smashes the throttle from every green light will soon start using more fuel every kilometre.
