How to improve fuel economy on Vauxhall Astra?

I've noticed that my Vauxhall Astra's fuel economy has been declining lately. What steps can I take to improve it and save on gas expenses?

Regularly maintain your car by checking tire pressure, changing air filters, and using the recommended fuel grade. This can help improve your Vauxhall Astra's fuel economy.

Try to plan your routes beforehand to avoid heavy traffic or long idling periods. This can also help save on gas expenses.

Make sure to avoid excess weight in your car as it can decrease fuel efficiency. Remove any unnecessary items and keep your vehicle clutter-free.

Consider upgrading to a more fuel-efficient model if your Vauxhall Astra is old and not performing well. It may be a worthwhile investment in the long run.

It's also important to drive at a steady speed and avoid sudden accelerations or decelerations. This can significantly impact your fuel economy.
