Mines the same. I have a 2006 auto 4wd s model. I was doing an average of 240 or so. The more 4wd use the lower it went. Now Im careful driving and not 4wheeling much(it says in the manual 4wd eats gas) and its getting higher. Last i checked, I got 275 miles. Hey, it could be worse.. jeeps get even lower milege.
this question is VERY old, and I doubt I will get points out of this BUT I really would like to help your pain/ agony. I have a 96 Ford 4 x 4 as well. I have THE same issue. there is nothing wrong ( or little). Because the vehicle is a 4 x 4 your mileage will be dumps because the vehicle turning both axles at same time. gas mileage in Subaru is horrid, so I hear because they are WONDERFUL cars but terrible on mileage! What I did to make mine run better.. I use Seafoam to burn sentiments and tiny debris out of gas tanks. It's about $15 BUT is cheaper than buying a brand new tank. there are more problems with older tanks because they are stainless steel so therefore they tend to get mysterious chips in them and clog up filter faster. Babysit your air filter A LOT more often if you live in windy areas. My elevation is over 4,000 ft, and the winds pick up the sands from Nevada and carry them over. The air is FILTHY here, so babysit the air filter. Also, buy a more expensive gasoline that burns cleaner and you should get a better result. This is why aircraft us jet av fuel. It's burned at the same plant as where gas and propane is made from mud hauled in. Consider your MAS as well. your air sensor has to read air coming in to the air intake and communicates with the computer that tells the pump I need so much fuel , etc. If the air sensor cannot read the air because it's plugged, clean it or replace it. I'd take a cigar cleaner and splash alcolhol on it to clean that eye out and therefore it has a better reading of how much air is coming in and how much fuel I will need coming to create my chemical reaction of 14:7:1 over the piston where the spark plug is. good luck
