My 86 4dr TurboD with 225Kmiles on it gets 24.5 to 26 in town and 26.5 to 27 on the highway, the ranges are winter and summer. I have attained 28 MPG only when running the dirt backroads at 2000rpm all day, or on a trip which included driving to Cooke City, MT on the switchbacks of Beartooth highway at low speeds keeping the turbo spooled up. It was so much fun putting a cloud of soot in the face of those tailgaters on that long winding road. 235 tires. Stock.
