Why is my Vauxhall Grandland's fuel economy decreasing?

I recently noticed that my Vauxhall Grandland's fuel economy has been decreasing. What could be causing this issue and how can I improve it?

This could be due to a number of factors including driving habits, tire pressure, and engine maintenance. I recommend monitoring your driving habits and making sure your tires are properly inflated. If the issue persists, consider getting your engine checked by a professional.

It's possible that your vehicle's air filter may be dirty or clogged, which can lead to decreased fuel efficiency. I suggest checking and replacing your air filter if necessary.

Have you recently changed your driving route or been stuck in traffic more often? These factors can also have an impact on fuel economy. Try finding alternative routes or using public transportation when possible.
