Gas $3.12/gal - What have you done to improve MPG?

[farside847]

Since the gas prices took a jump overnight, thought this would be a good subject to see how people are helping their MPG....

I have tried a few things myself. I started at about 12MPG:
- Tune up - gain 1MPG
- New plugs - nothing
- New K/N filter - nothing
- Elec Fan - gain 1MPG

So now I am up to 14MPG.

Things not yet tried:
- pcv filter
- acetone additive
- swap rear to a 3.08
- swap tranny to a 2004r
- farting in gas tank

PS:I have a 307v8 with a 2bb and a standard 3speed and 3.73 rear end.
