Summer blend must be here: averaging 44.4 mpg on current tank (1/3 of a tank so far)

You can get those numbers with a automatic if you dont go above the speed limit. If you drive 75-80mph like most people then your mpg will start to drop. The final drive on the 4 speed auto isnt geared as high as the 5 speed manual so your going to be running a higher rpm range which is less fuel efficient.
