How can I maximize the fuel efficiency of a Ford Ranger?

I've noticed that my Ford Ranger is using a lot of gas lately. What are some tips for improving its fuel efficiency?

One simple way to improve the fuel efficiency of your Ford Ranger is to regularly check and replace your air filter. A clogged air filter can significantly decrease your gas mileage.

Make sure to keep your tires properly inflated. Underinflated tires can cause your car to use more fuel.
