Two simple steps can save you hundreds of dollars each year in gas costs

Instead of driving all over town looking for cheaper gas, consider this: A little more air in the right places can save you a lot of gas — and money. It is simple: More air in your tires, and a clean air filter. And this money-saving tip won't take you even 15 minutes a month.

Two screws or a couple of clips, five minutes, and it's replaced.

Keep Tires Inflated…

About 1.2 billion gallons of fuel are wasted annually due to under-inflated tires, the NHTSA estimated in 2005. One easy way not to lose air pressure in the first place is to fill your tires with nitrogen instead of regular air. Thousands of nitrogen fill stations exist all over the country and a nitrogen fill is usually under $20 bucks. Because nitrogen is a larger molecule then air
