This is not in any way scientific, but my experience tells me the following things can cost as much as 5MPG during a 50 mile commute:
running head lights
driving in moderate rain
running heater blower on high
10mph or higher cross wind or head wind
air temps below 25 degrees
My current plan to try and minimize the amp draws and cold warm ups is to add a water and oil pre-heat system and to do a alternator delete with a large AH battery back-up. I hope to have it up and running on the red 92 VX in a couple of weeks.

Excellent post. Thanks friend. I checked the plugs, they don't look too good. I'll post pics. Def want you guys opinion on them, as I'm no "plug reading" expert, by any means.
I did manage to squeak out a few 58+ trips over the last few days, which were promising.
I'll make another update post soon. Some pretty sweet stuff has been going down on the project.
