How can I improve the fuel efficiency of my Ford Focus engine?

I have been driving my Ford Focus for a few months now and I have noticed that the fuel efficiency is not as great as I expected. Is there anything I can do to improve it?

Hi Sarah, have you tried replacing your air filter? A dirty air filter can greatly decrease fuel efficiency.

Another tip is to check your tire pressure regularly. Under-inflated tires can cause your car to use more fuel.

I have found that using cruise control on the highway helps improve fuel efficiency. Give it a try!
