How To Get Good Fuel Economy

Improving fuel economy

If you own a powerful car and you drive enthusiastically, you're probably not going to be blessed with marvellous fuel economy. However, there are various steps you can make to lower the amount of gas you use on any journey without driving like a miser. This article only majors on the most effective methods of reducing fuel consumption, if you need more tips please do a search on Google – there is a plethora of information out there…

Keep your car well maintained

Following the correct service intervals will keep your car running efficiently. New air filters will allow the free flow of air necessary for efficient fuel combustion, clean fuel filters provide a steady stream of petrol to the cylinders, and shiny new spark plugs will provide the spark needed to set the whole thing off. A thing of beauty! They key here is the efficient burn of the fuel air mix, which will allow more power to be extracted from a set volume of fuel. A new air filter alone could increase fuel consumption up to 10%.

Tyres

Underinflated tyres need more energy to roll. Keeping the pressures at the correct level can increase economy by up to 3.5%. Specialist fuel saving tyres are also available, although these may not perform so well on the track! Properly inflated tyres are also key to providing optimum levels of grip, so it's worth checking periodically.

Gears

Using higher gears won't give you lightning acceleration but will save fuel. Keeping your revs low (but not so low that your engine starts to struggle) is a good habit to get into when cruising. If you have a "Sport Mode" on your auto transmission, turn this off, as this will hang onto low gears for longer and may even prevent changing to the highest cog.

Accelerate hard to save fuel?!

A British automotive engineering consultancy claims to have unearthed proof that putting your foot down hard on the accelerator can actually be more fuel efficient than driving more conservatively. “It sounds totally counter-intuitive — and it is,” admits Cousins. The key to saving fuel, he says, is to accelerate hard until the engine reaches 2000 rpm, move up a gear, then put your foot down until you reach 2000rpm again. It’s all to do with internal friction. “Put simply, with your right foot down on the accelerator, the engine is working at its most efficient,” says Cousins. Above 2000rpm the benefits diminish and you start using more fuel, not less.
