Hey Bullitteers. Question on gas mileage. How far can most of you get on a full tank of gas? I'm not looking for the distance during road trips, just throughout the week. I filled up Monday morning, have traveled about 150 miles and have LESS than a half tank left. It's been a city/hwy driving combo and I haven't really floored the car that much. My 73 Datsun with leaky fuel vent hoses and a 12 gallon tank can get 250 miles per full tank. Wussup?
