Thanks to all of you for your ideas and support. Personel best of 60.8MPG.
Last tank changes were, 3 degree timing increase, new O2 sensor, platinum plugs, ign. wires, part time with fender enclosed, and lastly smoothed out the front end and blocked off 1/2 of the rad. intake. This was for the last 200 miles. Biggest change was being able to run closer to my normal commute. I'd say the tire change was also a big help. Had a gallon left but I was getting nervous about running out. Last tank was 56.60mpg so I'm happy till next tank!
