Hey spitfire, is your car a 5spd? What have you done on the interstate to increase mileage? Mine will get right at 37-38mpg on the interstate with my cruise set to 70mph.

I did get 41mpg on one road trip doing 70mph with the cruise set (with a trunk full of luggage and 1 passenger!). I made the same roadtrip again the next year and only got 37mpg while doing everything else identical. I still can't figure out why I couldn't duplicate it.

^Wind could have been a factor.

Mine is a 5 speed. I do not have cruise control, which can help especially if there are hills because then i can control the RPMs more closely without them rising drastically. I drive about the same as you right around 70mph. I also try to draft semis at a safe distance and just accelerate slower and make more planned decisions to pass and other maneuvers. Coasting on the Interstate is harder as you will lose speed alot quicker than on two lane or residential roads.

I should say I dont get 49 on the interstate that is on two lane highway sorry, but I do get above 40mpg consistently on the Interstate.
