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

I recently purchased a Vauxhall Astra and I've noticed that it doesn't get as good gas mileage as I expected. What can I do to improve its fuel economy?

One simple way to improve your Astra's fuel economy is to change your driving habits. Avoid sudden acceleration and braking, and try to maintain a constant speed while driving.

Regular maintenance is key for optimal fuel economy. Make sure to keep up with oil changes, tire rotations, and air filter replacements.

Check your tire pressure regularly. Underinflated tires can decrease fuel efficiency.
