How do I improve the fuel efficiency in my Vauxhall Astra?

I have noticed that my Vauxhall Astra is not as fuel-efficient as it used to be. Is there anything I can do to improve its fuel efficiency?

Regularly maintain your car by getting it serviced and changing air filters. This will keep your engine running efficiently and improve fuel economy.

Avoid speeding and rapid acceleration as this uses more fuel. Try to maintain a steady speed and drive at a reasonable pace.

Make sure your tires are properly inflated and aligned. Underinflated tires can increase fuel consumption.

Remove any unnecessary weight from your car, as this can also impact fuel efficiency. Only carry what you need for your journey.
