Hey there, I'm new here and looking for a little help. Last week, I purchased a 2014 town & country touring with a v6 and 40k miles. As advertised and from what I've read, I should be getting 17mpg on the low, I would even be okay with 16 city, but I am averaging 14.2 over the past 200 miles of city driving. I do not have a lead foot, the tire pressure is good, there are no engine lights or messages, and I am running unleaded gas. Is this normal?
