How do I improve gas mileage on my Vauxhall Astra?

I recently purchased a Vauxhall Astra and I'm noticing that my gas mileage isn't as good as I expected. What steps can I take to improve it?

First, make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage. Additionally, avoid overloading your car with unnecessary items, as this adds weight and can also decrease fuel efficiency.

Another tip is to avoid rapid acceleration and braking, as this uses more fuel. It's also helpful to maintain a consistent speed while driving on the highway rather than constantly changing speeds.

Regular maintenance is key to improving gas mileage. Make sure to get your oil and air filters changed regularly, as dirty filters can decrease your car's efficiency.
