· U.S. manufacturers benefit, because rising ocean-freight costs — reflecting fuel prices — make imports more expensive. Some production returns to the United States, and some shifts from Asia to closer exporters (Mexico over China). Since 2000, estimates Rubin, the cost of shipping a 40-foot container from East Asia has gone from $3,000 to $8,000. With oil at $200 a barrel, the shipping cost would be $15,000.

· Inflation becomes more stubborn. For years, the Federal Reserve has focused on “core inflation” — prices minus energy and food. The justification is that large food and energy price changes usually reverse themselves. But if they move steadily higher, that logic collapses. “While core inflation may be barely over 2 percent, that’s only of solace if you don’t eat or drive,” Rubin says. Overall inflation is twice that, about 4 percent.

Do not underestimate oil’s fallout. The world may have arrived at Peak Oil, when dwindling oil reserves no longer permit much annual increase in production. This may not be literally true; estimates of vast undiscovered oil reservoirs imply that Peak Oil is decades away. But governments that control 75 percent or more of known reserves are behaving as if Peak Oil is already here. They’re hoarding a scarce commodity by limiting new exploration. Meanwhile, production at some old fields is dropping rapidly. Spare capacity has been depleted as demand outruns new supply.

High prices close the gap. The grim price outlook by Rubin and others presumes that this situation persists. Of course, they could be wrong if higher prices cause demand to drop sharply and supplies increase unexpectedly. Saudi Arabia recently signaled a modest production increase. In the United States, prices have already led to less driving. In March, highway travel was down 4.3 percent from a year earlier. Buying patterns for autos have shifted. Through May, sales of sport-utility vehicles dropped 31 percent from a year earlier, reports WardsAuto.com. Oil demand is also stagnating in Europe and Japan.

But higher demand from developing countries and oil producers is offsetting the lower demand of wealthy countries. Consumption in these countries will rise 3 percent in 2008, projects the International Energy Agency.

There’s been a huge transfer of power to oil producers. Even at $100 a barrel, Saudi Arabia, Kuwait and the United Arab Emirates will earn almost $8 trillion in oil revenue between now and 2020, estimates the McKinsey Global Institute. More troubling are the political implications. “This has really strengthened the Iranians, Russians and Venezuelans to be more provocative in the world,” says Larry Goldstein of the Energy Policy Research Foundation. Although governments control crude supplies, private companies have dominated distribution. Anyone can buy oil at a price. Now oil could become a political commodity offered to friends at a discount, withheld from rivals.

How can we retrieve some of our lost power? The first thing is to get out of denial. Stop blaming oil companies and “speculators.” Next, we need to expand domestic oil and natural gas drilling, including in Alaska. Although we can’t “drill our way” out of this problem, we can augment oil supplies and lessen price strains. It might take 10 years or more, because new projects are huge undertakings. But delay will only aggravate our future problems.

Finally, we need to realize that high prices may stimulate new biofuels from wood chips, food waste and switch grass. Production costs of these fuels may be in the range of $1 a gallon, says David Cole of the Center for Automotive Research. If true, that’s well below today’s wholesale gasoline prices. To assure new producers that they wouldn’t be wiped out if oil prices plunged, we should set a floor price for oil of $50 to $80 a barrel, says Cole. This could be done with a standby tariff that would activate only if prices hit the threshold. Oil prices are unpredictable, and should a price collapse occur, Americans wouldn’t be deluded into thinking we’ve returned permanently to cheap energy. We’ve made that mistake before.

He averaged just 88.3 miles per gallon.

Most drivers would take a victory lap if they managed to squeeze that kind of mileage out of increasingly precious gasoline. Even on this, a bad day, Hudgin coaxed 28 mpg more out of his 2000 Honda Insight hybrid than its federal highway mpg rating.

Hudgin’s disappointment — he usually averages about 100 mpg this time of year — stems from his pride in being no ordinary driver.

He’s a hypermiler, part of a loose-knit legion of commuters who’ve made racking up seemingly unattainable mpg an art. And a sport.

Hypermilers practice such unorthodox techniques as coasting for blocks with their car’s engine turned off, driving far below speed limits on the freeway, pumping up tire pressure far beyond car and tire makers’ recommendations and carefully manipulating the gas pedal to avoid fuel-burning excess.

They endure not only occasional honks from other motorists angry at their slow-poke ways, but intentional discomforts, as well. Like keeping the air conditioning off and windows barely cracked on a more than 90-degree day. Or parking in the boondocks at shopping centers so they can motor head-first toward the exit rather than backing out of a space.

Just about anything for an extra one, two, maybe even four mpg. With their odd fixation and log-book scribbles obsessively tracking their mileage, the hypermiler community might in other times be typecast as tightwad eccentrics. But in an era of $4-plus-a-gallon gas, they’re garnering increasing attention as driving superstars, even saviors of the planet.

“More power to them if that’s important to them, and they are accomplishing a goal that also benefits society,” says Ron Cogan, publisher of Green Car Journal.

Automakers are taking notice. Honda will install an instrument in a new hybrid it will roll out next year that cues drivers for gas-saving actions, such as when to ease off the accelerator, says spokesman Sage Marie.

Hypermilers share their triumphs and secrets on a handful of websites. They also gather in some cities as a subset of clubs for hybrid-car owners, which many now are.

Driving safety advocates laud some of their habits — but heap scorn on others.

“Probably the most beneficial aspect of hypermiling is its emphasis on a less aggressive approach,” says Geoff Sundstrom, spokesman for AAA, formerly the American Automobile Association. “The downside of hypermiling is some of the techniques can be extremely dangerous.”

Turning the engine off while coasting can, in some cars, leave the driver without power steering or brakes and allow the possibility that the steering wheel will lock up. Drivers can endanger themselves and others if they go too slow for the pace of traffic.

How about that urge to “draft” trucks — follow close behind for less wind resistance — on the interstate?

“There’s another term for that. We call it tailgating,” Sundstrom deadpans.

Safety first

Hudgin, a 56-year-old professional pilot, says serious hypermilers always put safety before mileage. Sure, he doesn’t mind using a truck as a windbreak — but only, he says, if he can stay at least three seconds back.

During the afternoon drive with a reporter, he observes all traffic laws in a mix of city and highway driving.

But having to make a stop at Phoenix Sky Harbor International Airport, grabbing a quick taco at a Mexican restaurant and getting stuck in rush-hour traffic on Interstate 10 take their toll on his usual mpg.

Normally, Hudgin says, he can roll up 100 mpg in warm weather, about 90 in the winter. But on this day, the kiss of mileage death came when his hybrid’s battery started recharging, which causes the hybrid’s gasoline engine to work harder and burn more gas. Those few minutes on the freeway slashed his mileage temporarily to a paltry 48 mpg, according to the car’s computer. That’s 12 below the two-seat, three-cylinder Insight’s EPA mpg rating for highway driving.

Hudgin is not new to the mileage game. When Hudgin was young, an uncle drove a 1955 Morris Minor, a small English car, to Canada and bragged about 50 mpg. “I thought, ‘That’s phenomenal.’ And it made an impression on me.”

Hudgin has owned a series of compact vehicles known for their little engines and big mpg, such as a Subaru Justy and Chevy Sprint. He had a long commute, he says, and needed dependable and cheap cars.

Some mileage tricks he found himself. “I started going the back way, slowed down from 55 to 45 miles per hour and saw an increase of 16 mpg,” says Hudgin, who flies executive planes for the state of Arizona.

Slow going on the byways tacked 19 minutes onto his commute, but he says he didn’t mind.

In 2001, he bought his then-slightly-used Insight, an odd-looking car that was the first hybrid sold in the USA, though in limited numbers. It got the highest EPA mileage rating of any model until it was discontinued. He got 59.6 mpg from his first tank of gas.

Not bad, he says, but around 2005, he discovered the world of hypermiling, including Internet sites such as CleanMPG.com, Greenhybrid.com and several others where hypermilers share mileage tactics.

Finding miles online

Hudgin says tips culled from the sites helped him improve until in 2006, he averaged 112 mpg on a tankful while practicing to be part of a six-man team for the Insight Marathon, a mileage contest. All the claims are unverified, but Hudgin and other hypermilers say the proof is the car’s own mileage computer.

Others claim similar triumphs. Randall Burkholder of Blackwell, Okla., whose Insight was used in the marathon, says the team got 164 mpg. He says 100 mpg is pretty routine on his 82-mile round-trip commute to work as a machine programmer.

“We know what the cars are capable of,” he says.

Another hypermiler, Sean Welch of Coon Rapids, Minn., says he often gets more than a thousand miles out of the 10.6-gallon gas tank on his Insight. He says he uses the same techniques in his non-hybrid 2002 Hyundai Elantra and also gets astounding mileage.

“Hypermiling is a whole suite of tools. It’s half science and the other half is art, knowing when to apply them,” says Welch, 31.

Some of the science comes from a gauge hypermilers put into cars that don’t have one built in that offers a continuous reading of their gas mileage at any moment. Without such gauges, it’s hard to figure out what works or what doesn’t.

“There’s no magic pill,” Hudgin says. “You really need to change your driving style. If you’re talking on your cellphone (behind the wheel), it isn’t going to happen. You have to concentrate on your driving.”

Hypermilers have their own lexicon for their tricks.

There’s “pulse and glide,” in which the driver speeds up then shifts into neutral or turns off the engine to coast. There is “ridge riding,” which is driving the car off center in a lane to keep its tires out of the tracks worn into pavement from years of traffic.

A natural result, of course, of all this intense study is competition for bragging rights as top hypermiler.

Many will gather in Madison, Wis., on July 19-20 for Hybridfest, which will pit hybrid owners from Florida to California in a contest to see who can get the best gas mileage over a scenic, winding, 30-mile loop.

The entry classes cover a wide range of hybrids, from tiny Insights to one for the guy bringing a new Chevy Tahoe full-size SUV hybrid that is government rated at 21 mpg. “He’s pretty sure he can get 35,” says Eric Powers, who is organizing the event as part of the Dane County Fair.

Adapting to road, weather

The strategy behind winning such rivalries is knowing which techniques to use at different times, based on weather and road conditions. Not all work on any given day.

“If you leave some on the table, that’s fine,” says Wayne Gerdes, who runs hypermiling site CleanMPG.com and holds seminars. Gerdes says he gets more than 40 mpg out of his 2003 Ford Ranger pickup.

Drivers don’t have to be as extreme as the top hypermilers, however, to get better mileage.

Slowing down and laying off the brakes has helped California Highway Patrol Officer Heather Hoglund get about 10 mpg more out of her private car, a Toyota Prius hybrid.

But she says she’s cautious about using hypermiling techniques: “Don’t get so hooked on your hypermiling you don’t put your foot on the brake when you need to.”

Using a little gas for comfort

Hudgin’s wife, Laural says she happily uses her air conditioning and has stopped turning her engine off during stoplight waits “because it dragged down the battery.”

Yet, by driving smoothly in her diesel-powered 2004 Volkswagen Golf and carefully trying to time stop lights to avoid waits, she averages nearly 50 mpg, she says, about 10 mpg better than the car’s EPA rating.

“She’s a hypermiler in her own right,” Louis Hudgin says.

But like any spouse, he admits, “I have to bite my tongue while she’s driving.”

TELL US: How do you make every mile per gallon last?

You can get more gas by volume by purchasing gasoline at that time. You’ve probably noticed that gas prices soar shortly before an upcoming holiday when many of us travel farther distances to visit family and friends. So try to fill up before that price-jump surprises you! Be sure your gas cap is tight or your gas might be vaporizing into thin air, literally. If your vehicle is in poor running condition it uses more gas. So invest in a tune-up. Replace a dirty air filter because a clogged filter can damage your engine, reducing gas mileage efficiency. Check those spark plugs as well. Under-inflated tires are gas-guzzlers too, so have the air checked. I personally dislike using cruise control because it feels I’m not in control. However, if you don’t have that issue, you should use cruise control, as it does keep your driving speed steady and that does help fuel economy.

Turn off your engine if you’ll be idling for more than thirty seconds. Starting and stopping the engine uses some fuel; sure, but idling the engine for long periods of time uses more. Plan ahead. The less you have to stop the better your gas mileage. So when you see other drivers racing to the red light to beat you they are wasting gas. Better to attempt to catch as many green lights as possible, as the less stopping you have to do, the better gas mileage you’ll get. Accelerate slowly and take more distance and time when you brake.

This way of driving is effective at reducing gas mileage. The more weight you’re carrying with you, the worse gas mileage you’ll get. Attempt to stick to the basics. For safety’s sake too, it’s not a good habit to be lugging around heavy items in the carriage along with passengers. When you must travel with luggage, etc., it’s best to put them in the trunk, as hauling stuff around on a rack messes up aerodynamics and your car’s workload increases.

Lastly, I’ve heard that both running the air conditioning as well as driving with your windows open are going to reduce your fuel economy by as much as 10%. Well, whether you’re hot or just want some fresh air, do whichever you like. There is really no major difference between driving with the windows down or using the AC when it comes to conserving fuel. AC uses a mere 1-mile per gallon. Obviously, you never want to run your AC while windows are down! Let a cool head prevail!

1. Buy a good used sub-compact car that gets great mileage and use it for the daily commutes to work and store, etc.

2. Car-pooling and sharing the cost of gas or charging per passenger, per ride, will reduce your own costs.

3. The tried and true mechanic’s advice: Tune-up and keep the tire pressures at optimum.

4. Driving habits we can recall from drivers ed: Reduce speed, accelerate gradually, slow down before traffic signals require you to brake.

5. Maximize each trip efficiency: Do more things each trip and plan your route in advance.

6. Don’t carry extra weight around in the car – ditch the spouse and kids!

It has virtually no noticeable effect when driving on the highway, and while it’s a little more noticeable when it comes to city driving, it may not be worth the discomfort if it’s a particularly hot day. Another thing I try to do is avoid breaking abruptly. Breaking gradually is better for your mileage. Hopefully these tips will help you save some gas money!

In the summer time it is possible for some of the liquid gasoline to turn into vapors inside your gas tank. To avoid this fill the tank to the normal full level and try to keep it there. This reduces the amount of space available for gasoline vapors and actually increases gasoline mileage.

You can also improve gasoline mileage by keeping the tires of your vehicle full of air. Check the tires before you have traveled a long distance or before it gets to warm during the day. Warm air expands in the tires and may give a slightly false reading. Keeping the tires full with air may save up to 5 per cent on your total gas mileage.
