How to increase fuel efficiency in my Vauxhall Astra?

I recently bought a Vauxhall Astra and I feel like I'm spending too much on fuel. What are some tips to increase its fuel efficiency?

First and foremost, make sure that your tires are properly inflated. Underinflated tires can significantly decrease fuel efficiency. Also, try to drive at a constant speed and avoid unnecessary acceleration and braking. This will help you save fuel.

Another tip is to avoid carrying unnecessary weight in your car. The more weight in your car, the more fuel it will consume. So, clean out your trunk and only keep essential items in your car.

Regular maintenance is also crucial for fuel efficiency. Make sure to get your car serviced on time and replace any worn out parts, such as air and fuel filters.
