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

I recently purchased a Ford Galaxy and I'm looking for ways to improve its fuel efficiency. What tips or tricks do you recommend?

Regularly maintaining your car's engine and keeping it clean can greatly improve fuel efficiency.

Try to avoid aggressive driving and speeding, as both can greatly decrease your fuel economy.

Check your tire pressure regularly and make sure they are properly inflated, as underinflated tires can drastically reduce fuel efficiency.
