As petrol continues to rise in
price, there has never been a better time to think about eco-driving!
Regardless of the vehicle you are
driving, there are techniques you can use to save fuel and to minimise
your impact on the environment.
- Ask yourself: "Do I really need to drive?" It's
the shortest journeys - less than two miles – which cause the most
pollution and are inefficient in terms of fuel consumption. A straining
cold engine will produce 60 per cent more pollution than a warm one.
Yet it's these shorter journeys that are ideal for walking or cycling.
- Plan your route . A bit of forethought can save
much wear and tear - for the car,and the driver. Try to take the most
direct route and go off peak if possible. Sitting in congestion means
you are often doing zero miles per gallon. If you have to commute by
car, think about car sharing, Park and Ride schemes or public
transport.
- Have your vehicle serviced regularly . This helps
maintain efficient running and good economy. Inefficient,
under-serviced engines can reduce fuel economy by ten per cent or more.
Catalytic converters are environmentally friendly - but only if they
are properly maintained.
- Check your tyres . Correct tyre pressures will keep
wear down and fuel economy up. Under-inflated tyres need replacing more
often (itself an environmental problem) as well as being dangerous.
Anybody who has cycled on under-inflated tyres will appreciate how much
extra effort is involved! Make a point of checking them at least once a
week.
- Obey the speed limits . Try to "feather" the
throttle as you reach your cruising speed. Doing 56mph uses 25 per cent
less fuel than 70mph and a smoother driving style can bring significant
fuel saving. But never coast to save fuel; vehicle control must not be
compromised.
- Reduce the drag factor by removing roof racks and
carriers when not in use. Driving with the window open also increases
drag and lowers fuel economy. Remove unnecessary boot luggage, avoid
heavy accessories and wide tyres that add rolling resistance. Air
conditioning lowers fuel economy so use the vent settings as much as
possible instead.
- Use gears effectively - change gears sooner and
keep the car driving in as high a gear as possible as much as you can
to reduce the speed and fuel consumption of the engine, use block
gearing when possible (skiping gears, e.g. gear 1-3 or 2-4 or 3-5)
generally don't let the engine race unless you really need to.
- Use “accelerator” sense . Do you go straight from
the accelerator to the brake? You would save fuel if you planned ahead,
and rather than have to brake as you hit traffic, gently let the speed
of the vehicle bring you to a halt as you join a queue. There is no
point in rushing and then having to brake to come to a sudden halt.
- Reverse in when you park. When you start off again,
the engine will be cold and at its most fuel inefficient. If you can
drive smoothly away without having to reverse when the engine is cold,
not only will you save fuel you will also have better visibility.
- Be a tank miser. Why fill the tank up to the very
brim? If you do so, you may be carrying around additional fuel, which
in turn means that you have more weight on board than is necessary.
That extra weight will itself reduce fuel efficiency.
