You have to consider that mine needs a set of injectors and weighs close to
9K lbs. On the highway, I can get about 15 if I can keep it at 60 mph. I have been putting off changing the injectors, figuring that they will last until an engine swap. I don't drive it much right now, so the fuel mileage doesn't bother me.
