So, if most of the fuel-saving additives and gadgets on the market are worthless, what's a fuel-sipping driver to do?
Instead of following the advice of late-night infomercials and Internet ads, listen to the EPA. Keep your car well-maintained. Drive efficiently by accelerating slowly, coasting when you can and doing your best to avoid slamming on the brakes. Try to minimize unnecessary wind resistance by taking external roof racks and cargo carriers off your car when they're not in use. Keep extra weight out of your car. If it's August, you probably don't need to keep that bag of kitty liter in your trunk in case you get stuck in the snow. Trust me, the odds of that are really low.
Of course, the best way to minimize the amount of gas you use is to drive your car less. Combine trips when running errands. Carpool, or take the bus. Walk where you need to go if you can. With all the money you'll be saving on gas, you'll be eating a lot of Cheetos. You'll need the exercise.
