  1. How to get best MPG

    General Commander Discussion
    Okay so I know Commanders aren’t known for their amazing MPG, but I’m going away to college next year (I’m in my senior year of high school) and I have a Commander that I love and I don’t have money for a second car to get better MPG. College is 550 highway miles away. What mods can squeeze...
  2. Improving Gas Milage

    General Commander Discussion
    Trying to do what I can to improve my gas milage on this car. Researching cold air intake systems (an opinions on best one?) and maybe replacing spark plugs. Just bought the car with 98K miles on it. 3.7L V6 2007 Commander. Any ideas to improve it's performance under the hood?

    Regular Service / Maintenance

It kept dropping as I was driving. It has now...
  7. Real world gas mileage?

    General Commander Discussion
    Wife and I for the first time ever actually agree on a vehicle we both like. The Commander. We don't plan to buy for at least another 4-6 months, but we are going to test drive one on Saturday with the 4.7L. Our biggest concern is the gas mileage as here in NY gas is one of the higher prices...
