Fueleconomy.gov, a federally run site, searches for the cheapest gas prices in your area. It also provides up-to-date information on hybrid, diesel, and alternative-fuel vehicles, as well as their respective tax incentives.
CleanMPG.com is a forum where drivers can share and discuss their favorite tips on “hypermiling”—clever and sometimes odd techniques that drivers can use to exceed their vehicle’s EPA fuel economy rating.
Petrofix.com sells “price protection” for gasoline. Drivers can lock into a fixed gas price for up to two years at a cost of roughly 25 cents a gallon. If gas prices dip below the locked-in rate, drivers can still buy at the lower price. But if prices rise above it, Petrofix will send you a “check for the difference.”
