I tested these by resetting the trip meter in 10 mile segments on my way back so they are not the most accurate. It did appear that for every 5 MPH I slowed down, I gained 2 MPG on the reading.
PS I did not make this thread for people to fight. Please keep the purse swinging to a minimum or use a different thread.
Almost identical to the http://www.mpgforspeed.com
calculations for each speed, more accurate than people give it credit for!
This is inputting 36mpg highway into their calculator:
Speed Effective MPG
55 MPH 36.0
60 MPH 34.9
65 MPH 33.1
70 MPH 29.9
75 MPH 27.7
80 MPH 25.9
