Can anyone help with a fifth gear change for a 1994 Geo Prizm? I have been able to reach 42mpg under ideal conditions (flat ground, 55mph, non-Winter seasons, and no traffic to consider). I am expecting to do a 100 mile commute for a few months increasing my present trip by 5X. Most of the driving will be highway so I thought a gear change to my 5-speed might improve my 38.5mpg average. I would love to be able to reach a repeatable 45mpg average without insighting road rage in fast New England/Boston 70mph traffic. My wife said she did not want me to do extensive aero mods and my budget is very modest. I do have access to a mechanic friend and I like the lowered suspension and the belly pan.

My first post,

Neal
