bishi - '95 mitsubishi eclipse rs
90 day: 38.22 mpg (US)

My commute consists of about 100 miles round trip every day. About 75ish miles of that is flat freeway driving, 10ish miles of 55mph somewhat hilly road and the last bit is the drive to and from the highway. I do know that my car is OBDII, they changed the eclipses in 95 to be OBDII but not sure if it is within the same specs since it is not a 96, I also think I am having a vacuum leak which I am wondering if that is causing any problems getting readings because of my map sensor that is controlled by vacuum. I did some more experimenting today and coasting downhill in gear would read anywhere from 80-120 mpg depending on speed and grade of the hill, but every time it would read that high I would hit the clutch and the number would drop down to 30's maybe 40 at most, then if I continued to hold clutch in but rev the engine up to around 2k the mpg would just up to 70mpg or so and upon letting off the gas it would drop right back down in the 30's again.
