Reliable detection of Win98 may not be possible. When Haslett's Bob Rich drives to the Upper Peninsula to vacation this summer, there will be more on his mind than good times. With gas so expensive, the retired General Motors Corp. engineer now considers how much fuel he can conserve. It is a challenge to see how much fuel economy I will get.
Motorists can improve gas efficiency by how they handle their cars.
The amount of brake use, speed, tire pressure and maintenance can drastically affect vehicle mileage. If you took someone who was a very aggressive driver and taught them to drive more conservatively, they could probably save 30 percent and maybe as much as 50 percent of their fuel use. The biggest impact on gas mileage, according to Clark, is the speed you drive. In highway driving, the U.S. Department of Energy said the most efficient speed is 55 mph. As you drive faster, wind resistance increases, hurting fuel efficiency.
