How can I improve the fuel economy on my Vauxhall Astra?

I've been noticing a decrease in my Astra's fuel efficiency lately. Are there any tips or tricks I can use to improve the fuel economy and save some money on gas?

The first thing you should do is check your tire pressure. Under-inflated tires can significantly decrease fuel efficiency. Keep them at the recommended pressure for your Astra model.

Another tip is to avoid idling your car for long periods of time. Idling leads to wasted fuel. If you know you'll be idling for more than a few minutes, turn off your engine.

Regular maintenance is key for optimal fuel efficiency. Make sure to get your oil changed and have your air filter checked and replaced regularly.

You can also try using a fuel additive or cleaner to improve the overall performance of your engine and increase fuel efficiency.
