If it is a manual, then one should be able to get one-and-a-half to two times the stock FE with mods and great hypermiling. Topping 40mpg on tank averages should be "easy" in this car, I think. Pump up the tires, remove unneeded weight (100lbs or more if you can find it), do some simple aeromods like an airdam and grill block, and learn to pulse and glide with the help of a reliable gauge that tracks engine load and RPM. You'll be topping 40mpg in a few months.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
