What about keeping tires inflated? My car has a fuel efficiency (average mpg) readout. When my tires are at 30psi (just below normal) I get 18 – 20 mpg. When I inflate them to 37psi (just above normal), I immediately get 24 – 27 mpg average. That’s a ~30% savings on fuel costs.
I find that monitoring gasoline commodity prices on a daily basis can help predict when gas stations will be raising/lowering prices in the near future. (As usual, prices tend to rise more quickly than fall).
