Alright, my Bronco II is coming together i still have a problem though gas mileage; i havent done any calculations but i estimate it around 6 mpg right now, not good im down to 1/8th tank after about 120 miles from a full tank, no bueno. there are no known problems at this point so what could it be im running b12 through along with some lucas oil so that should help a bit but not gonna give me back 11 more mpg what is the problem?
