OK, with that said, when I want to optimize my mileage, I don't look too much at the actual speed I'm travelling, I try to minimize my RPM's. For example, when starting from a stop, gather speed gradually rather than punching it. I try to keep my RPM's below 2,800 at all times and it really saves a lot of gas.

But come on, who's really going to drive a $60,000 car down the highway at 55 MPH?
