FAQs

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.

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, 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.
