Two things specially noted from the article:-
a) 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 percent of the time it was. “There’s little difference between brand-name gas and any other,” says AAA spokesperson Geoff Sundstrom.
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.
b) Cars run on gasoline—but not all cars need gasoline to run. In fact, 6 million cars on the road today (mostly from U.S. manufacturers and built since 1998) are “flexible fuel” vehicles that can run on E85, a fuel that is 85 percent ethanol and only 15 percent gas. When Minneapolis resident John Schafer bought a car in late 2001, he chose a Chevy Tahoe because it’s a flexible-fuel car. Since then he’s filled up almost exclusively with E85. The big difference he’s noticed: Cars using E85 get about 15 percent fewer miles to the gallon. But it’s a drawback he’s willing to put up with. “I’m committed to the technology,” Schafer says. “With E85, it burns cleaner so it won’t pollute as much.”
While E85 generally costs less than regular gas, there is some concern that it may grow prohibitively expensive as demand outpaces supply: By 2006 ethanol was not just being used in E85—it also composed 15 percent of every gallon of gas sold. Supplies of ethanol are likely to grow thin, which could drive up the price of E85. And even die-hard Schafer says he won’t buy E85 if it starts to cost more than gasoline.
