    Is it fuel injected or older carbs ? If carbs then you can get them balanced.
    If fuel injected then try buying a bottle of fuel injection cleaner in a car shop like Halfords. Makes a big difference if your injectors are dirty/clogged.

    I cleaned the air filter last week and am now getting an extra 20% on a tank. Amazing how it was running so rich for lack of air. Extra power too.

    Had that exact problem on a Nissan Micra. Good advice Doc.

    If your filter was clogged badly enough to cause such a difference then it is overdue a change by a huge amount.

    No thats whats annoyin me :L thats why Im asking is there anythim that could be causin it to use up the fuel without actually burnimg the fuel, as in mixture to strong or somethin? :)

    Well any faulty componant would throw up the engine warning light.

    How often is it serviced? Fuel filter changed? This is a regular service item on older Nissans that hardly anyone every changes. How are your tyre pressures? Have you got a boot full of junk?

    Other then those things, driving style and driving conditions can have a huge effect on economy, much more then people realise. The example I used above of my old skyline getting 400 miles to a tank, this was steady speed motorway/N road driving, however on the same car I could also use a whole tank in less then 30 miles on track.:eek:

    Fuel filter would have never beem changed, everything else would be changed frequently amd tyre pressure would be fine, the fact that you could get 400 miles on a tank is saying theres something definitly wrong with mine, driving style would normally be gentle acceleration and changing gears as soon as possible and speed would normally be 60 mph then 80 mph sometimes and 100+ the odd time

    Yeah it was full of oil and bugs.
    It's a motorbike so you don't replace them - just clean with petrol and clean oil, problem was it is has ram-air from two big holes at the front and so got a lot more clogged up than I was used to.

    That explains that, oiled filters are a different thing altogether to the dry filters used in cars.

    You've just diagnosed your own problem. On the vast majority of cars once you go over 60mph the fuel economy falls. If you already short shift and accelerate gently then try keeping a steady 60mph on longer drives and I'd say you'll notice a difference. 80-100mph will guzzle fuel on a 1.6.

    He's right, running at anything over 2000 RPM wastes fuel. Keep an eye on your RPM when cruising. Around 55 mph should keep you under the magic 2000 RPM or close to it, and is usually the most fuel efficient cruise speed.

    Also quick takeoffs from junctions and the lights etc., as temping as they are, really guzzle fuel like nobodies business. Cut out the quick take offs and you'll watch the MPG soar.

    I can't remember anytime in the last year, I was driving under 2000rpm.
    Keeping your engine revs too low, destroys the engine, and is not good for economy either.
    For most petrol engines, rev between 2000 - 3000 should be fine on flat surface. If you are climbing up the hill, you most likely need more.

    Yea thats true but it would normally be drove at 50-60 most of the time :)

    You must be driving a honda 50 then mate, or a perhaps hairdryer. ;)
    No one said anything about rpm climbing hills, of course it will be higher.
    The engine/gearing combination on every car is different. Either way if your particular buzzbox isn't capable of cruising on the level at around 2000 rpm then keep it under 2300-2500.

    You can still do the rally style driving when you feel like it, you just don't have to do it all the time.
    Hypermiling is a very challenging skill and art all of its own, and can be taken to all sorts of levels.
    Google it to you see.
    Without trying too hard, I've managed a 5 mpg improvement, saves me several hundred yo yo's a year.
