Sounds like a job for http://ecomodder.com/forum/showthrea...you-15182.html!

I have heard 55 MPH many times, although I have not read it in these forums, just that it is better than 60, let alone 65, or eighty. Generally speaking, the slower that you drive, the better, but about a liter of gas an hour just idling. The best way to know for sure is with instrumentation, which can be as simple as an OBD-II dongle and Torque or another app. You can get an idea of this in: http://ecomodder.com/forum/showthrea...0-a-30169.html
