Fuel-saving hacks: Small changes can cut consumption by 30%

Would you like your car to consume up to 30% less fuel? Although it may seem unrealistic, small changes in habits can bring significant savings. Although implementing just one of the following tips might not have a substantial effect, combining several can result in surprising outcomes.

Economical driving starts with caring for your car. The first step is ensuring the correct tyre pressure. Too low a pressure increases rolling resistance, which raises fuel consumption. If the pressure is 7 psi lower, fuel consumption rises by about 5%.

Next, pay attention to the vehicle's technical condition. In petrol cars, the ignition system must be maintained. A dirty air filter and old spark plugs can increase fuel consumption by up to 10%. Removing unnecessary luggage from the car is also worth doing, especially dismantling unused roof racks.

Modern cars often have a gear assist feature that indicates when to shift to a higher gear. Following this guidance is essential because contemporary engines are designed to work at low rpm.

Shifting up at around 2,000 rpm or slightly more can lower fuel consumption. For example, at a speed of 30 mph, the difference between driving in third and fifth gear is about 30%. Naturally, high gearing is only for maintaining speed, and you need to downshift when accelerating.

Another essential habit is engine braking and using neutral. When approaching red lights or driving downhill, consider engine braking. In this case, fuel is not supplied to the engine, which saves fuel and reduces wear on brake discs and pads.

Don't be afraid to use neutral, either. Many cars with automatic transmissions have a "coasting" mode, equivalent to neutral. Neutral is helpful for short distances at low speeds, such as in residential areas or decelerating before exiting the motorway. Ensure you don't obstruct traffic, though.

Aside from technical issues, attentiveness behind the wheel is significant. Look at the road, not just the car in front of you. If you see a red light from a distance, don’t accelerate. Sometimes, it’s worth paying attention to pedestrian signals. The car light will also change when the green pedestrian light starts blinking.

While driving on country roads, maintain a safe distance from the vehicle in front. This allows for efficient reaction to other drivers' manoeuvres and saves fuel. It also enhances safety.

In summer, drivers often wonder whether it’s better to turn on the air conditioning or open the windows. GM has proven that opening windows is more economical at lower speeds. However, due to deteriorated aerodynamics, air conditioning is the better solution on the motorway, albeit used wisely.

On hot days, it’s worth opening the windows first; after driving a few hundred yards, close them and turn on the air conditioning. This helps cool the vehicle’s interior faster.

The most straightforward advice is to rethink whether you need the car every time. Perhaps it’s worth walking to the shop or cycling to work? It’s cheaper and healthier.
