Alright, me and my friend have a bet going, and i am 99.9% sure i am correct. He enjoys driving his jeep on the road with 4WD on because "he thinks it handles better", which is an entirely different story that i argue with him against. But anyways i told him that he is getting worse gas milage w/ 4WD on, especially for having it on for no reason. So he came back and said no it gets the same milage. Does anyone else have an opinion on this? Im almost positive i am right, what do you think?
