Something different Building for MPG.

I thought about doing an electric conversion to the Falcon. I'm not too concerned about performance in that car and I don't mind cutting up a Ford. The problem is it's just not cost effective right now. I'm sure in a few years once the technology evolves this type of thing will be a viable option.

One more thing... about 5 years ago I put a high quality synthetic fluid in my Swinger's differential (8.75 with 3.23 gears.) With that single upgrade I immediately improved the highway fuel economy by 6%.
