    Tips to improve Fuel Economy

    Here are some very good tips on improving your vehicle's Fuel Economy / Increase Fuel Efficiency / Mileage. With increasing fuel prices it is becoming more and more prudent to use them.

    Use your gears wisely.

    Driving in the highest gear possible without labouring the engine is a
    fuel-efficient way of driving. A vehicle travelling at 60kmph in third gear
    uses 25 percent more fuel than at the same speed in fifth gear

    Drive smoothly

    Think ahead! By applying light throttle and avoiding heavy braking, you can
    reduce both fuel consumption and wear and tear. Try to predict traffic at
    junctions and when in queuing to avoid accelerating and then braking.
    Research suggests driving techniques can influence car fuel efficiency by as
    much as 30 percent.

    Switch off your engine
    There are two schools of thought on this one. Switching your engine off for
    short periods of time can actually increase fuel consumption, as it requires
    more fuel to get the engine started. Also your catalytic converter will no
    longer be running at full temperature and so your car will be less
    efficient, increasing the amount of pollution you cause. However if you are
    stopped for more than a few minutes then your car will simply burn less fuel
    with the engine stopped.

    Drive off promptly to prevent wasting fuel
    Don't leave your engine running when you first start up. Drive off straight
    away if you can, but drive gently until the engine has reached its normal
    operating temperature. This doesn't increase fuel efficiency as such, but it
    does mean your engine is switched on for less time.


    Lighten your load
    Think carefully about what you need on a journey. if you do not need
    something, do not pack it. Remove roof racks if not needed. The lighter the
    load, the lower the fuel consumption, and emissions, and the higher the fuel
    efficiency.

    Tyres effect fuel efficiency
    It is estimated that about 50% of tyres on the road are under inflated.
    Aside from increasing the rate of wear, this wastes fuel and decreased your
    fuel efficiency. Check your tyre pressures every fortnight. Worn tyres will
    also decrease fuel efficiency (and your safety!), so check the tread
    regularly. If you are replacing tyres then consider some of the newer 'Eco'
    tyres that are designed specifically to increase fuel efficiency.

    Car Windows
    Driving with your windows open drastically reduces your fuel efficiency, far
    more so than putting the air conditioning on when motorway driving. So in
    those hot summers(?) preferably keep the windows shut, and the air
    conditioning on if you want to keep cool. Of course the air conditioning
    decreases fuel efficiency too, so try not to over use it.

    Invest in a new fuel efficient car

    New cars come in all shapes and sizes, but it is possible to pick a new car
    that can greatly reduce your fuel bill, and your fuel emissions.

    Size matters. Choose an economical car - small cars use far more fuel
    efficient and produce lower emissions than large cars.

    Drive the most fuel-efficient car that meets your needs. Compare models and
    classes. Even similarly sized cars can vary in fuel efficiency by up to 45%.

    Consider diesel engines (with a particulate trap), and LPG (Liquefied
    Petroleum Gas) and CNG (Compressed Natural Gas) fuelled cars - all have
    lower CO2 emissions than standard petrol cars.

    Consider 'hybrid' vehicles - they combine a conventional engine with an
    electric motor and battery. These offer reduced fuel consumption and CO2
    with potentially lower emissions of all pollutants.

    Diesel Engines
    If your going to buy a diesel, ensure it is a new 'common rail' type, as
    these are approximately 10% more efficient than older diesels. also replace
    (or clean if applicable) air cleaner elements as often as is required by
    your vehicles servicing schedule.

    Regluar Maintenance maintains fuel efficiency

    Air Filter:
    One of the most common reasons for a drop in fuel efficiency is a dirty
    intake filter. This will decrease the amount of air entering the cylinders
    of the engine resulting in incomplete combustion. Check the filter regularly
    to ensure that it is clean.


    Spark Plugs
    Ensure your spark plugs are in good condition. Renew the plugs and wires at
    intervals specified by the owners manual. This will keep all cylinders
    firing properly resulting in higher efficiency.




    Lube Oil:
    Change the lube oil at intervals specified by the owners manual. Use the
    recommended oil only especially in newer cars. Use of an engine flush before
    changing the oil will help to get rid of a lot of the dirt that collects in
    the engine that a normal oil change will not remove. On older engines it is
    advisable to use an oil treatment agent. This basically thickens the oil
    which creates a better seal between the piston and the liner, preventing
    blow past and consequent loss of combustion pressure, resulting in higher
    fuel efficiency.

    Exhausts alter fuel efficiency
    Most cars have special sizes for the exhaust. When cars are reasonably old
    the silences has to be changed. The garage people always try to fit a size
    that they have in the garage it self. Which might not be the exact size
    recommended for the car. The wrong size a bigger or smaller silencer size
    effects on the MPG of the car and the HP of the car. It may be cheaper to
    put another size than your recommended size for your car but on the long run
    it will cost you in many ways, especially on fuel consumption. Always put
    the recommended size of the exhaust that is indicated in your car manual
    because the car company knows how to optimize the performance of your car.
