How to improve fuel efficiency in Vauxhall Astra?

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

Regular maintenance is key. Make sure to keep your Astra's engine well-tuned and check for any issues that may be affecting its performance.

Consider changing your driving habits. Accelerating and braking aggressively can greatly impact fuel efficiency. Drive at a steady pace and avoid sudden bursts of speed.

Check your tire pressure regularly. Under-inflated tires can decrease fuel efficiency. Keep them properly inflated according to the manufacturer's recommendations.

Use high-quality fuel. Cheap gas may save you money in the short term, but using a premium fuel can actually improve your car's fuel efficiency in the long run.
