Which engine size gets more miles per gallon? The 2.4 liter or the 2.0 (gas) engine. I was wondering because I am about to get a patriot since they get great gas mileage and I do not like small cars. I am going to be driving 30 miles on the interstate every day which engine size would be best suited for me? and how is the cabin noise, right now i drive a 2dr wrangler jk and can't even hear myself thank. -thanks in advance, brian
