The combined EPA for my Forester is 20 MPG, but I was getting twenty-seven, before my ex started driving it. I left her my Ultragauge, hoping it would help her drive better, so she closed the car door on it.
Did the car come with the roof rack cross-members? I removed mine (and then my ex harassed me, saying that she needed them), but read that to remove the rails, you need to remove the headliner--it would be a mess.
Improving fuel economy is great, but only if the investment pays off. Sometimes we make modifications that do not have a return on investment, but maybe someone else can take our idea and do better.
What have you tried that did not work?
