I can't quite understandthe MPG calculations from reading the owners manual. I have a 2014 Cruze ECO, so I have afew extra features in the instrument panel relative to MPG calculations. I always liked to utilize the calculations that were available on my other cars. With those vehicles, youcould always reset the Average MPG calculations anytime you wanted, which Ialways liked to do as I started a trip, so that I could really see what fueleconomy I was getting on the freeway. With my Cruse ECO, I don't believethat you can reset the calculations, but you can change the settings so that itwill compute for one of these; 1) the past 25 miles, 2) the past 50 miles, or3) the past 500 miles. I'm not sure when it actually starts those miles -for example, how far back does it go when I change the setting from say, 50miles to 25 miles? And, if I'm looking for the "latest" averagemileage - that will change for the most recent timeframe - wouldn't it be bestto just leave the setting at 25 miles?
