What can I do to improve my Ford Ranger's fuel efficiency?

I noticed that my Ford Ranger's fuel efficiency isn't as great as it used to be. What can I do to improve it?

Regularly maintaining your Ford Ranger is key to improving fuel efficiency. Make sure to keep up with oil changes, tire rotations, and air filter replacements.

Check your tire pressure regularly. Under-inflated tires can reduce fuel efficiency.

Avoid idling for long periods of time and use cruise control on the highway. This can also help improve fuel efficiency.
