The 87.2 was one way
the round trip was more like 55-60.
The ZX2's manual transmission is much deeper geared than the automatic. IIRC it is a .75 5th with 4.10 final! So the auto has the advantage of much lower revs on the highway. The Escort sedan transmission is better geared for cruising though, so I will swap it in when the auto goes ka-blewy! For the time being I am focusing on getting a 50 mpg tank with sights set on 75 mpg.
Dave, you will see tomorrow
but what works for me is cruising between 40-50 mph while keeping my instant readout high. It maxes out with 60 mpg @ 40 mph. I EOnC as much as possible, with my mpgs between 300-500. I DWL on hills and am not afraid of losing speed. The aero mods have helped majorly, since I might be close to the Honda Insights (Cd=0.25) drag.
