My 95 Legacy L wagon got 25mpg on my last full tank..
3/4 highway doing 80 most of the time with another passanger, and 100 lbs of luggage
1/4 in town lots of stop and go and being heavy on the throttle.
i figured this was pretty good. since my tires were 2psi low, and i think my cats are a little clogged up, but not enough to cause a CEL. oh and noisy lifters in the passenger head..
i'm sure i can get 30mpg once i get new fuel, and air filtes. new plugs, wires, high flow cat, and 34/32 psi in the tires. oh and take the led out of my right shoe.
