FAQs

Yes, it can do.

Hot weather on its own does not always increase fuel consumption, but the way we drive in summer does. Air conditioning, heavier traffic and carrying extra weight all make the engine work harder, which means more fuel is used.

So while the temperature plays a part, it is usually those combined factors that make the biggest difference.

It depends on how you are driving.

At lower speeds, opening the windows is usually more efficient than running the air conditioning. However, at higher speeds, open windows can create drag, which can actually reduce fuel efficiency.

In most cases, a balanced approach works best. Use air conditioning when needed, but avoid running it constantly if you are trying to keep fuel consumption down.

Yes, more than most drivers realise.

Incorrect tyre pressure or uneven wear can increase rolling resistance, which means the engine has to use more fuel to keep the car moving. Even a small drop in pressure can have a noticeable effect over time.

Keeping your tyres properly inflated and in good condition is one of the easiest ways to improve fuel efficiency. Learn more about tyre pressure and other FAQs in this handy guide.

While there’s no perfect speed, usually, cars achieve their optimal efficiency at speeds between 45 and 50 mph. Fuel economy varies among vehicles, but it is also influenced by additional factors like tire pressure, the presence of roof racks, and driving style.

Coasting in neutral or with the clutch pressed can save fuel by reducing engine drag while rolling downhill. However, if you are going uphill, it’s better to keep the car in gear as this enables the engine to help you climb up and make use of the available power. This also applies when changing gears – shifting too soon can cause unnecessary strain on your engine, resulting in a higher fuel consumption. For best results, changing gears at the right rpm is recommended. This ensures that your engine is running as efficiently as possible and can help you save fuel.

The answer to this question is yes – changing gears can use more fuel than keeping the engine in a single gear. To get the most out of your fuel, it’s important to drive smoothly and keep the number of gear changes you make to a minimum. Driving at a steady speed where possible can help with this, as well as using cruise control on highways or long drives.
