Why does my Vauxhall Mokka's fuel efficiency decrease over time?

I recently bought a Vauxhall Mokka and noticed that the fuel efficiency has decreased over time. What could be the cause and how can I improve it?

The decrease in fuel efficiency in your Vauxhall Mokka could be caused by a variety of factors.

One possible reason could be dirt and debris build-up in your air filter, affecting the air flow to the engine and reducing its efficiency.

Another factor to consider is your driving habits. Frequent acceleration and braking can use up more fuel, so try to maintain a steady speed and use cruise control if available.

Regular maintenance and tune-ups can also help improve fuel efficiency. Make sure to follow the manufacturer's recommended maintenance schedule for your vehicle.

Lastly, make sure to check your tire pressure regularly. Under-inflated tires can decrease fuel efficiency and also be a safety hazard.
