Helen (Salt Lake, Utah) - 1984 Toyota Pickup
Helen moved to Salt Lake City from Milwaukee. Her gas mileage improved from 300 miles to 400 for a tank. But then she got new tires, and her mileage dropped back to 330. Where did her miles go? She may have an inaccurate gas gauge, but Tom and Ray say she first needs to figure her miles per gallon, not per tank. She may have been filling up less regularly when she first moved.
