How can I improve the fuel economy in my Vauxhall Corsa?

I've noticed that my Vauxhall Corsa is not getting very good gas mileage. Are there any tips or tricks I can use to improve the fuel economy?

Regularly check and replace your air filter to ensure proper air flow, leading to better fuel economy.

Avoid driving at high speeds or aggressive acceleration and braking. This can greatly impact fuel efficiency.

Check your tire pressure regularly and keep them properly inflated. Under-inflated tires can decrease fuel efficiency.
