Everybody wants to find cheaper gasoline prices, right? Luckily, there are simple ways to save money on gas. By following one or more of these gas-saving tips you can easily save hundreds of dollars a year on gas.

Go to Gasbuddy.com Relying on volunteers from across the country, this website reports the latest gas prices in your area. Enter your zip code and discover both the cheapest and most expensive places to buy gas. There's usually a .25 cent or so difference between the two, which translates into a $5 savings for a 20 gallon tank. And if you live in cities like NY or LA, the difference can be as much as .60 cents!

Don't buy gas in "good" neighborhoods If you can, go to gas stations in less affluent areas. This is because richer areas have higher property taxes, so to compensate they make the gas more expensive.

Don't use highway gas stations Few people are willing to get off the highway to buy gas, and the highway gas stations know it and mark their gas higher than normal. But it's not unusual to find much cheaper gas right off the exit ramp. This little detour is often worth it.

Use a gas rebate card A typical card offers a 10% introductory rebate, which reduces to 5% later. It's a great way to save hundreds of dollars a year--but only if you pay off the balance every month!

Try running your car with water This technology has become massively popular recently. Basically, you install a device in your car that separates the hydrogen and oxygen in water. The resulting mixture is called "Brown's gas," which is supposed to run your car smoother, cleaner, and cheaper than regular gas. You might have heard about a company in Japan that recently unveiled a car that runs on water, so there's seems to be something to this.

Use cash instead of credit Some gas stations encourage their customers to pay cash by offering a discount on gasoline prices. If you use cash, the gas station doesn't have to pay a credit card transaction fee. Everybody wins!

Let's face it, gas is not going to get cheaper. In fact, some experts think we might be paying $10 or even more per gallon eventually! You can't do much about that, but you can learn how to save money on gas right now. You'll be glad you did.
