Well, believe it or not, my gas hog was actually my last car: 1992 Honda Civic VX! Of course it was no longer stock, but instead home to a turbocharged B18A1. I think it's ironic that I destroyed this champion of gas mileage in favor of a gas guzzling power plant. I did make some impressive numbers though - 240 whp / 236 wtq - pay special attention to the last. That torque was nuts, and it was so much fun.
Anyhow, I got between 19 and 29 mpg, depending on how hard I drove it, and I usually averaged about 22 mpg.
