10 tricks to save you fuel  when driving an automatic car [UPDATED]

10 tricks to save you fuel  when driving an automatic car | SuzukiSave money in your automatic with these insider tips on driving fuel efficiently.

Petrol prices make up a massive portion of the day to day costs of your car, and are notoriously unpredictable. In fact, “Fuel takes up to 40 - 45% of the running costs of your car,” says Willie Venter, a Fleet Consulting Manager at EQSTRA Fleet Management. Added to this, automatic cars are slightly less fuel efficient than manuals, according to stats by the USA’s Environmental Protection Agency.

As a driver of an automatic car, it feels like there’s not much in your control to save on petrol costs, but there are driving techniques that’ll extend your fuel to the end of the month. 

1. Keep your momentum

It’s science - a body in motion stays in motion, and therefore uses less energy and fuel. Don’t brake unless needed, and driving slowly and consistently will keep your car going forward.

 2.    Don’t keep your foot on the brake

Resting your foot on the brake pedal, no matter how lightly, immediately applies drag to the car, which hugely impacts fuel economy. Says How Stuff Works, “It'll place an unnecessary burden on the engine and transmission. You'll wear out your brakes rapidly, as well.”

3.   Tyres properly inflated 

Your car only touches the ground on, quite literally, a handful of places. Each tyre has a portion as big as the palm of your hand that actually touches the road - and this has a huge impact on your driving and fuel efficiency. An underinflated tyre causes your car to drag, increases stopping distances and is generally unsafe.

 4.    Don’t drive angry 

Racing to the robot, fast braking and crazy accelerating all chow fuel rapidly. Says the US Environmental Protection Agency, Aggressive driving can lower your fuel consumption by 33% at highway speeds and by 5% around town. Accelerate gently, and pull away slowly to save petrol.

 5.    Buy petrol when it's cool 

Science, again, explains this one. Liquids expand in heat and you’ll get more bang for your buck when the petrol is compact in the cold morning or evening air.

 6. Transmission

You’ll find that some automatic cars stay in lower gears longer than is fuel efficient. Try coax the transmission into shifting earlier than it wants to by taking your foot off the accelerator after 50 Km/h. Accelerate slowly when you’re in the higher gears.

7. Make fewer trips

The more trips you make, the less fuel you’re going to save. This because once your car is parked for a few hours, the engine has cooled down and it will use more fuel to for the first 10 kilometres or so. Try combine going grocery shopping and picking up your kids from their after-school activities if you can.

8. It’s all about maintenance

When your car runs smoothly and is in good mechanical condition, you’ll be able to get the best fuel economy from it. How Stuff Works says that sending your car for regular maintenance can boost fuel economy up to 10 per cent. Regularly schedule maintenance so that car parts will last longer, allowing you to save money through less fuel consumption and reducing repair costs.

9. Cruising when you can

The RAC UK say that cruise control actually helps with saving fuel when driving on a consistent flat surface such as highways and freeways. This is due to driving at a constant speed, which cancels out unnecessary acceleration. Using your cruise control on steep hills could increase your fuel consumption as the cruise control will attempt to keep your vehicle travelling at a constant speed which uses more fuel.

10. Don’t lose traction

Your tyres are more likely to slip on wet or gravel surfaces, and each time that happens you lose fuel mileage as well as endanger yourself and others. Make sure to take care when starting off on unpaved and slippery roads and slow down on rough surfaces.

All of these small, manageable changes add up to savings you’ll feel between pay day.  Read our post on what to do at a petrol station and remember that not all  petrol stations are made equal..
