What can I do to improve the MPG of my Vauxhall Astra?

I recently bought a Vauxhall Astra and I am disappointed with its fuel efficiency. Is there anything I can do to improve its MPG?

First and foremost, make sure your tires are properly inflated. This can greatly affect the fuel efficiency of your car.

Regularly servicing your car can also help improve its fuel efficiency. Be sure to check and replace your air filter if necessary.

Avoid unnecessary idling and try to drive at a steady speed on the highway. This can also help improve your MPG.
