I just got my first Scooby doo, a 2002 Forester with 53,000 miles on it. After 2 tanks of gas (87 octane with Methanol) I'm getting 22 1/2 mpg. I live near Denver at about 5200 feet elevation and have a automatic transmission. I've been using the air conitioner and driving to work, some stop and go, and freeway speeds up to 75 mph, is this the kind of milage I can expect? I thought that these were supposed to get 28 mph on the highway.
