OK folks thanks. I'm now the proud owner...or rather my daughter is of a White Rogue Sport. I suspected the ECO button did next to nothing, but the overall gas mileage is pretty good and it feels like a nice solid piece of kit. We'll forgo the ECO button. She's not heavy on the pedal and neither am I, mainly I'm thinking of the effect on the Engine & Trans rather than gas savings. I never boot my vehicles around.
