Yay, the Ford has a manual transmission.
That's where your biggest potential for savings lies in that vehicle. As Pete says, read the hypermiling/ecodriving tips list. You want to cruise in the highest gear you can without lugging, miminize your use of the brake pedal (and engine braking), maximize the time spent coasting in neutral toward stops & turns, and avoid idling (shut it off when stopped for more than ~30 seconds).
I don't know how capable a driver you are, but advanced techniques that save a lot of fuel are engine off coasting and pulse & glide (though this one is arguably harder on the vehicle as well). Check those out as well ... and don't try this stuff in traffic. Learn in a safe, isolated location if you're going to try those so you don't crash your car when you inevitably screw up.
And... welcome to the forum!
