It's been a while since I had my '95 (v-6 ATX) , but I'd say for a real-world estimate , expect to get about 25/26 mpg city driving & about 32 mpg highway . As for mileage on a tankful (highway , on a trip) you'll get about 325 miles before you'll need to look for a gas station , and around town mileage per tank ... usually much less , maybe about 250  ) .
