What is the best way to improve the fuel efficiency of my Ford Ranger?

I recently purchased a Ford Ranger and I am looking for ways to improve its fuel efficiency. I want to save money on gas and reduce my carbon footprint. What are some practical tips or modifications that I can do to improve the fuel efficiency of my Ford Ranger?

One of the easiest things you can do is regularly maintain your truck by changing the air filter and spark plugs. This will help improve your engine's performance and fuel efficiency.

Consider adding a tonneau cover to your truck bed. This will create a more aerodynamic profile and reduce wind resistance, leading to better fuel efficiency.
