Cruise control is a nice option, it makes driving a set speed easy. However, I hear people refer to it as a device that offers good mpg. Aside from the fact that the unit on our CRV automatic causes unneeded downshifts, I don't think CC offers the best mpg. I think the best mpg would be from a steady throttle setting, with uphill speeds being reduced and downhill speed increased. This is the stragety I employ, going uphill slower to reduce drag when there is also the penalty of ascention and go faster downhill when there is a sort of "excess" potential energy being released, easily overcoming increased drag. Is this correct? I don't think the varied throttle of cruise control is efficient.
