MPG in or M6

[ALLEGROAE]

Have done a lot a traveling in my daughter's 2009 Altima 2.5S

I did the last part at about 80mph and tried to determine whether it was better to remain in D or go to M6 while in the interstate going up and down hills.

Any input?

Your girl have a great car. She must be happy to have it.

I haven't tried any long drives in the manual mode, but I did get really good gas mileage on my trip to Huntington Beach a few months ago. I live about 127 miles away, and before I left I filled up and when I was back home (round trip) I still had just below a quarter tank left.

Oh, I forgot to mention I have the 3.5SE so I can only imagine that the 2.5S would get even better mileage. I'd assume the CVT would get the better of the two, just because it usually keeps the tach pretty low unless you're hauling a**.
