Papo is talking about the fuel consumption calculator reading as a real time calculation while on the highway after a reset once up to speed. I bought my 370 this time last month. Its a daily driver... I routinely see even up to 33mpg on the way to work, 63 mph in 6th, cruise control set. I chuckle inwardly knowing the better I do on the freeway, is merely offsetting losses I'll see on the streets... Its a little game that plays out daily in my head... Whatever it takes to drive past just one more BP.
