My 1987 2.6, at 75,000 post rebuild, about 255,000 miles total, with a semi-stock Mukini, stock tires, and no emissions stuff gets anywhere between 20 and 22 mpg in my running around. I drive a combination of twisty country road, interstate, and city each way to work and back -- I get about 20.4 doing that -- when everything is working right. When the bowl vent valve went out I got about 8-10mpg, and had similar poor mileage when the aux acceleration valve went out.
