Clark Howard's Tips

April 11, 2008

It used to be that weather was the topic of choice for small talk. But these days it's gas and the high prices at the pump.

Callers are telling Clark that some gas stations won't let you fill up your tank completely; they cap you at a certain dollar limit. This helps protect them from drive-offs and bum credit card numbers in the age of inflated gas prices.

If you go back 3 years ago, the cost to fill up was 40% what it is today. That's an enormous change in a short time.

Since we can't control what we pay at the pump, we'd better start controlling other factors. In Denver, 400 cars have been equipped with technology to monitor how you're driving and let you know how to maximize fuel economy on the road. So far this experiment has yielded a 20% increase in fuel economy. Clark himself has become obsessive about using cruise control, even on suburban drives.

Years before computers were routinely in cars, Volkswagen helped increase fuel economy by 30% in its stick shift vehicles. They had a light that would flash and beep to alert you when to shift gears. Most drivers tend to shift too early and waste fuel.

Many more automated solutions will be coming in the next few years. But for now, it's all about controlling our behavior as drivers. That means no jackrabbit starts. When Clark got his first hybrid, a Honda Insight, he averaged about 58 miles/gallon. On the highway, he was getting 70-77 miles/gallon. It's all a matter of what you're willing to do -- be it drive a smaller car, drive smarter or drive less.
