Not sure on the mileage, but I drove a 95 Talon TSi from Birmingham, Alabama, to Denver, CO. Only thing was that 8 hours into it, the tires were so bald that one blew from the heat, and I dropped onto the wheel. Almost lost control going 80+, but managed to get it to the side of the highway. After a big rig pulled over and took me to a gas station, I got a tow truck to a hotel, had to stay the night. The next day was sunday, couldn't find a wheel for my car to save my life since most places were closed. On monday I found a Probe GT wheel that fit, Bought 4 new all season tires and was back on my way. After that, my friend and I would drive 6 hours, sleep for 3, switched off all the way back. It was QUITE the trip to say the least, but I do remember getting 38 mpg, and we were going about 80-90 the whole way back. Not bad for a 4 banger turbo. Other than that, I've driven from Littleton, CO to Spokane and Seattle, WA a few times since my family is all there.
