Been driving my AWD Mavi with 2.0 Ecoboost mix of city and highway, last week just about all highway, and best I’ve gotten at the pump is close to 25mpg avg. Last week I mixed up using eco mode and regular mode and the only noticeable thing I’ve found between the two is the earlier shifting less responsiveness to the accelerator in eco mode. When I filled up at the pump today my average mpgs came out to 23.5 mpg. Does eco mode make a big difference in overall mpgs or will driving in regular mode and just keeping my foot out of the throttle achieve the same effect? I also just switched over to regular 87 gas today. To see how that adds up next week.
