Greenfleet - Driving Tips

Reducing fuel consumption means reducing greenhouse gas emissions and fuel costs - regardless of the car you drive. Here are some really simple tips to help everyone drive more efficiently.

Drive smoothly

Aggressive driving can use as much as one-third more fuel compared to conservative driving. Avoid accelerating or braking too hard, and try to keep the steering action as smooth as possible.

Tune and service the engine

A well tuned engine can improve fuel economy by up to four per cent. Change the oil regularly and follow the car manufacturer's recommendation on servicing.

Keep the tyres at the correct pressure

Correctly inflated tyres are safer and last longer, and they also reduce the amount of energy required to keep the vehicle rolling. A tyre that is under-inflated by one psi (pound per square inch) can reduce fuel efficiency by as much as three per cent.

Travel light

For every extra 45 kilograms (100 pounds) carried in a vehicle, the fuel efficiency can drop by two per cent, so keep the boot and rear seat clear of any unnecessary items that just add weight to the vehicle.

Take the roof rack off

Remove roof racks or roof bars if they are not being used to carry anything. They reduce the aerodynamic efficiency of the vehicle and create drag, reducing fuel economy by as much as five per cent.

Use the correct engine oil

Always use the recommended grade of motor oil. Using the manufacturer's recommended lubricant can improve fuel efficiency by one or two percent. Higher quality motor oils can also help your engine operate more efficiently.

Use higher gears

The higher the gear, the lower the engine speed. This can improve fuel efficiency, so use the highest gear appropriate, without causing the engine to labour at an ultra-low rpm.

Automatic transmission vehicles will upshift through the gears more quickly and smoothly if the driver eases back slightly on the accelerator when the car has gathered sufficient momentum.

Avoid excess idling

Idling gets a vehicle nowhere but still burns fuel. Turn the engine off when you're in a queue, or waiting for someone, until you need to drive.

Avoid high speeds

The faster you travel, the more wind resistance you'll encounter and the more fuel your vehicle will consume just to maintain speed.

Travelling at 110km/h uses up to 25% more fuel than cruising at 90km/h. For city driving, 60km/h is the most fuel efficient speed.

Maintain the distance

Leaving a sensible distance between your car and the vehicle in front gives the driver ample time to anticipate obstacles and to brake evenly.

Use air conditioning sparingly

Air conditioning puts added strain on the engine and uses additional fuel when operating, so limit its use to particularly hot days. On milder days, use the fan instead of air conditioning.

Check the air filter

The air filter keeps impurities from damaging your engine. Replacing a clogged air filter can improve fuel economy by as much as 10 per cent while helping to protect your engine.

Avoid rush hour or traffic jam hotspots

If you can travel outside of peak times and avoid known areas of heavy traffic, you'll spend less time stuck in queues and slow-moving traffic, thus consuming less fuel.

Conserve momentum

Think ahead when driving. For example, slow down early to let red traffic lights change to green, rather than stopping completely. Also, speed up a little before reaching the start of a hill and then allow the vehicle's momentum to carry the vehicle up the hill without working the engine harder.

Keep calm

When you are not calm, you are more likely to make judgement errors. Fuel efficiency is all about smoothness. Judgement and keeping calm is absolutely crucial to achieving fuel economy.

Use the handbrake on slopes

Many motorists do not use the handbrake when stopped temporarily on a slope. Instead, they either partially disengage the clutch (on manual transmission vehicles), or use the accelerator (on automatic vehicles), to keep the vehicles from rolling back. Both actions use fuel unnecessarily.

Break records

John and Helen Taylor (right with Greenfleet CEO, Sara Gipton) proved that combining good driving with the right car, can help to break Guinness World records for fuel economy.
