Re: Terrain's ECO Mode and Bluetooth!
I don't even know why GM made "Eco" an option to turn on/off. Turning it on gives you marginally better mileage (slightly quicker upshifts/lower idle rpm) yet turning it off doesn't noticeably improve performance. There really isn't a reason to turn it off unless you are bugged by the slightly rougher idle.
