At one time I was getting ~27mpg. Lately (past 6 months?), it dropped to ~22/23. I thought it might be the plugs, so bought a set. Unfortunetly, I haven't been able find the time to put them in. Anyway, this weekend I found that the parking brake cable was binding and therefore never fully releasing the parking brake. I think the drag induced by the parking brake wasn't helping my milage.
If your milage doesn't seem that good, you might consider checking the parking brake cables.
I noticed that there was a lot of chafing on the brake cable housing; the plastic housing was rubbed off exposing the metal housing. I suspect it was chafing against the Fwd Tie Rod being the tie rod had a flat where the cable would touch(this is the left side of the car, BTW).
Hopefully, the milage will go back up, but I still need to put in those plugs!
