I get much worse economy than this on my 92 900T with 55k miles. I'm lucky if I hit 21 mpg, normal is 20 mpg or slightly below, at highway driving. My mechanic (who is pretty good and reasonably priced) couldn't find anything amiss with the car when he last looked it over. Any idea what could cause this awful economy?
