Driving Tip Number 12
18th July 2008
As soaring fuel prices continue to hit the headlines, motorists cannot fail to be interested in ways to get the most miles out of every tank of petrol. Regardless of your choice of vehicle, there are techniques you can use to save fuel and at the same time minimise your impact on the environment. These techniques are part IAM Fleets Advanced Driving courses, which has delivered eco-benefits through fuel efficiency methods since the IAM was established in 1956.
Ask yourself: "Do I really need to drive?": Short journeys that are generally less than two miles 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. Walk or cycle where possible instead.
Plan your route: Take the most direct route and go at off-peak times if possible to save fuel and time. Sitting in congestion means you are often doing zero miles per litre. Consider car sharing, Park and Ride schemes or public transport (if available)
Have your vehicle serviced regularly: 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 reduce wear and helps fuel economy. Under-inflated tyres need replacing more often (itself an environmental problem) as well as being dangerous. Make a point of checking them at least once a week.
Obey the speed limits: Try to ‘feather’ the throttle when you reach your cruising speed. Doing 70 km/h uses 25 per cent less fuel than 110km/h and a smoother driving style can bring significant fuel saving.
Reduce the drag factor: Remove roof racks and carriers when they’re not in use as well as unnecessary boot luggage and heavy accessories. Driving with the window open and using air conditioning increases drag and lowers fuel economy, so use the vent settings 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 (low sulphur/aromatics) locally.
