New here, poor gas mileage
Posted: Wed Apr 20, 2011 5:07 pm
Hey guys,
I'm new here...just picked up a 1993 Legacy L AWD Wagon in early February for a daily. The car has 192,000 miles on it, and I'm just trying to figure out why I have poor gas mileage. I usually get around 200 miles to a full tank...I'd think I'd get around 300 or so normally.
I picked up the car from a dealership, so I don't know how the maintenance was performed by the previous owner; the dealer had the clutch assembly replaced, as well as an oil change, new spark plugs and spark plug wires at my request (I took it to a shop of my choice).
The car threw a CEL, and I originally found this site as I found a diagram showing how to figure out OBD-I codes here, so thanks for that. I'll get the code ASAP, but any ideas what could cause the bad gas mileage? Bad fuel filter, bad o2 sensor would be my first guess...? The car sounds like it has an exhaust leak, but between the 4 or 5 early model Legacy's I've seen, they've all sounded about the same as mine.
Any tips or pointers?

so i get a little more then 200 miles to a tank normally. But my car is boosted with upgrades that im sure dont help with my economy.... lol. Definitely check the code and you might as well replace or check out the easy stuff. Spark plugs and wires are a good start but did you get the stock oem replacements? The correct spark plugs to use in Subaru engines are NGK V-Powers, part no. BKR6E11 for the EJ22, gapped somewhere between .038 and .043 inches( the set i just picked up were gapped from the factory at like .039 all around) . Also the fuel filter is very cheap and easy to replace.
