"My gas isn't better for your car; it's just more expensive."
Oil companies spend lots of money explaining why their gas is better than the competition's. Chevron's gas, for example, is fortified with Techron, and Amoco Ultimate is supposed to save the planet along with your engine. But today, more than ever, one gallon of gas is as good as the next.
True, additives help to clean your engine, but what the companies don't tell you is that all gas has them. Since 1994, the government has required that detergents be added to all gasoline to help prevent fuel injectors from clogging.
State and local regulators keep a close watch to make sure those standards are met; a 2005 study indicated that Florida inspectors checked 45,000 samples to ensure the state's gas supply was up to snuff, and 99% of the time it was.
"There's little difference between brand-name gas and any other," AAA spokesman Geoff Sundstrom says.
What's more, your local Chevron station may sell gas refined by Shell or Exxon Mobil. Suppliers share pipelines, so they all use the same fuel. And the difference between the most expensive brand-name gas and the lowliest gallon of no-brand fuel? Often just a quart of detergent added to an 8,000-gallon tanker truck.
