How do I increase the fuel efficiency of my Ford Galaxy?

I recently purchased a Ford Galaxy and I am looking for ways to improve its fuel efficiency. Are there any specific maintenance tips or modifications I can make to achieve better fuel economy?

One way to increase fuel efficiency is to regularly check and replace your air filter. A dirty air filter can decrease fuel efficiency by up to 10%.

Another tip is to avoid idling for long periods of time. If you anticipate being stopped for more than 30 seconds, it's better to turn off your engine.
