Make the grade: Many people think you have to put premium-grade gasoline into your vehicle for maximum performance. Not so, according to the Automobile Club of Southern California.

Using premium-grade fuel in a vehicle designed to use regular is a waste of money, according to AAA, which advises using premium fuel only in high-performance vehicles that require higher-grade gasoline.

All fuels sold in the U.S. contain detergents to prevent the build-up of deposits in the engine’s combustion chamber, AAA notes on its Web site, www.aaa-calif.com .

DETROIT (Reuters) - Toyota said on Tuesday it would fix all Tundra pickups sold in the United States for the 2000 to 2003 model years to address a risk that part of the truck's frame could corrode, causing spare tires or even the gas tank to drop to the road.

In November, Toyota Motor Corp had recalled 110,000 Tundras sold in 20 cold-weather states, saying exposure to heavy road salt could cause the corrosion. Toyota spokesman Brian Lyons was unable to say how many additional vehicles would be covered by the additional repairs.

The repair campaign comes at a time when the world's top automaker is trying to recover from a damaging series of recalls that have tarnished its reputation and cut into its sales and financial results.
