No in for real there buddy no need to be a dbag either
Calm down I wasn't trying to be mean, I thought you were making a joke about Ford ecoboost.
As far as I know the "eco" light under the mpg indicator is like a glorified vacuum gauge, it tells you that you are driving in a fuel efficient manner.
EDIT: I think when you said eco boost you meant MDS? where the engine runs on 4 cylinders to save fuel? I don't think that was around in 2005.
