How to increase fuel efficiency

The 5.6-liter V8 makes it a very powerful truck and it's very quick for its size, but the fuel economy estimates are close to 10 MPG. How can you improve on that? Are there any modules worth purchasing to increase MPG?

I think each one of us is aware that gas costs continue to increase, well, it is not surprising that many drivers are downsizing to a used compact, or even becoming environmentally friendly with a pre-owned hybrid. But that trend is also driving up the cost of used compact and hybrid automobiles on the industry, according to Kelley Blue Book. Have you any idea how to finance a car with bad credit?
