my V6/1991's mileage is 17 in town (if already warmed up) and 31 ... 25 Hwy.
A mileage of 31 with this car on hwy is best. 29,5 ... 26 is average on hwy
(maximum speed at 75mph). Lower than 25 is only under worse conditions (e.g.
12 is while speeding; 15,2 is at an average speed of 95mph .... yes!!! and
at the Rockies)
