Why is my Vauxhall Crossland's fuel economy worse than expected?

I recently bought a Vauxhall Crossland and I noticed that the fuel economy is not as good as the manufacturer claims. What could be causing this issue?

There could be several factors contributing to a decrease in fuel economy. Check your tire pressure, as low pressure can increase fuel consumption. Also, try to avoid excessive idling and opt for smooth, steady acceleration when driving.

Have you been using the recommended fuel type for your vehicle? Using lower than recommended octane gasoline can result in decreased fuel efficiency.

It is also possible that there is an issue with your air filter, which can affect the fuel to air ratio. Have it checked and replaced if necessary.
