What can I do to improve the fuel efficiency of my Ford Ranger?

I recently purchased a Ford Ranger and I've noticed that I'm not getting as much mileage as I expected. What are some ways to optimize the fuel efficiency?

One of the easiest ways to improve fuel efficiency is to make sure your tires are properly inflated. Underinflated tires can decrease fuel efficiency by 0.2% for every 1 psi drop in pressure.

Another tip is to avoid idling or warming up your engine for extended periods of time. This can waste fuel and decrease fuel efficiency.

Consider using a fuel injector cleaner to improve the performance of your fuel system. This can help remove any built-up deposits and increase fuel efficiency.
