How to improve the fuel efficiency of my Vauxhall Astra?

I've noticed that my Vauxhall Astra has been consuming more fuel than usual. Are there any tips or tricks I can use to improve its fuel efficiency?

One simple way to improve fuel efficiency is to make sure your tires are properly inflated. Underinflated tires can cause your car to use more fuel.

Another tip is to avoid idling your car for extended periods of time. This can waste fuel and decrease efficiency.

Regular maintenance, such as changing air filters and spark plugs, can also help improve fuel efficiency.
