25 mpg is a lot to ask. Slow down A LOT. Don't go over 55, and shoot for 50 mph max. Take a different route to avoid the interstates. A lot of interstates have parallel rural routes. Air up your tires to sidewall maximum. Subject to argument, but I believe that if you use mid-grade or premium fuel AND increase the engine timing to "just before ping" then you will save money on fuel - vice using low grade and standard ignition timing. Do the standard tuneup items - spark plugs, wires, air filter, thinner motor oil. You might want to consider upgrading the ignition to a hotter coil (40 or 45k) and 9mm or better spark plug wires. The you could gap the spark plugs an extra .05 or .075.
