With global warming now high on everybody's agenda, there has never been a better time to think about Eco-driving, (practised by Hi-Way Drivings' clients for many years)
Regardless of the vehicle you are driving, there are techniques you can use to save fuel and to minimise your impact on the environment.
These techniques have been part of the Advanced Driving process. delivering eco benefits through fuel efficiencies, since the IAM was first established in 1956.
Ask yourself: "Do I really need to drive?" It's the shortest journeys - less than two miles - which cause the most pollution and are the most 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.
Have your vehicle serviced regularly. This helps maintain efficient running and good economy. Inefficient, under-serviced engines can reduce fuel economy by 10 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 and tear down and fuel economy up. Under-inflated tyres need replacing more often (itself an environmental problem) as well as being dangerous. Make a point of checking them every week.
Obey the speed limits. Try to 'feather' the throttle as you reach your cruising speed. Doing 56mph uses around 25 per cent less fuel than 70mph and a smoother driving style can bring significant fuel saving. Never coast to save fuel; vehicle control must not be compromised.
Reduce the drag factor by removing roof racks 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.
Buy green fuel - and use less of it. If you get stuck in traffic, switch off the engine. Find out if you can buy low sulphur diesel (City diesel) or cleaner petrol locally.
Use accelerator sense. Do you go straight from the accelerator to the brake? You could save fuel if you planned ahead, and rather than have to brake when you hit traffic, gently let the speed of the vehicle bring you to a halt as you join the queue. There is no point in rushing and then having to break to come to a sudden halt.
Reverse when you park. When you start off again, the engine will be cold and at it's most 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 up to the very brim? If you do so, you may be carrying around additional weight which will itself reduce fuel efficiency.
