Norris explains:
Let’s say my friend Ana buys 10 gallons of gasoline in a cold place like the
Canadian tundra. And I buy 10 gallons of gas in the warm state of Florida.
My friend Ana will be able to drive further than I will with those 10 gallons.
That’s because gas expands at warm temperatures. But its energy content
does not.
There’s a gizmo gas stations can put on individual pumps that adjusts for
temperature differences. But each one costs a couple thousand bucks a pop.
Dave Maurer is with the US Government Accountability Office.
“There actually have not been a lot of studies done on the benefits and costs of installing this
equipment. Really what we found is that it’s not really known.”
Right now different states do different things. California has just started a
major study on this topic. But without much research, Maurer said it’s tough
for policy makers to make decisions.

Lots of new hybrids and electric
cars are coming to the market. But some
say you don’t need an expensive new car to
get really good gas mileage. In the second

Julie Grant met one group of guys who says

and drive like your grandmother:
John Stine – aka Johnny Mullet – has always been crazy
about fast cars and big trucks.
But in the past year, this self-described country boy put
aside the hot rods and four-wheel-drive pick-ups and bought
an old Chevy Metro with a tiny 3 cylinder engine. He made a
few changes to make it more aerodynamic such as taking off
the passenger side mirror and even the radio antennae.
And, Stine also started driving really slowly.
It took a while for Johnny Stine’s wife to come around to the
changes.
John Stine: “What did you think at first?”
Mrs. Stine: “At first?”
John Stine: “I’m a nerd. You’re crazy.”
Mrs. Stine: “I thought he was a big nerd. I thought ‘oh my
God.’”
John Stine: “What are you doing to my car?”
That all changed pretty quickly as prices at pump went up.
Her nerd went from geek to chic.
Mrs. Stine: “Anything to save gas. We have a big truck. It
was costing us over $160 a week in fuel. But when he got
57 miles to the gallon, I was just like, ‘wow, what a
difference.’”
(sound of car talk)
Stine is meeting up today with about 20 other motor heads
from Ohio, Pennsylvania, and as far as Virginia. They’ve
gathered at a state park to check out each other’s souped-
down vehicles.
The parking lot is not lined with macho- muscle cars with 20-
inch rims. These guys drive refurbished Ford Festivas, Geo
and Chevy Metros on the skinniest tires possible.
Paul Keim says they’re just trying to save a few bucks on
gas. But his wife isn’t completely sold on this hobby.
“Ask her. The lady in the green shirt, she’ll tell you, my
name is ‘cheap bastard’.”
Keim says his wife does appreciate his gas saving tips.
She’s picked up 5 miles per gallon – just by keeping up the
tire pressure, changing the oil regularly, and, adjusting the
nut behind the wheel.
“You are the nut behind the wheel. Once you adjust your
attitude, and your driving style, you can get incredible
mileage.”
So, what do we need to change behind the wheel?
(sound of car doors)
John Stine is going to give us a few tips.
First, pay attention to your aerodynamics.
Julie Grant: “It’s pretty warm, am I allowed to have the
windows opened?”
John Stine: “The windows open when we’re sitting is fine.
As I’m driving, I like to keep them up unless it is very hot.”
Open windows are bad for aerodynamics. Air conditioning
wastes gas.
So, there are sacrifices. You might get a little sweaty – just
carry some extra deodorant.
Everyone here today drive cars with a stick shift because it
means better gas mileage.
Stine does whatever he can to keep momentum and not stop
at a traffic light. That can mean coasting very slowly up to
an intersection.
Some guys here say it’s been tough to adjust their driving
habits. To drive slowly – especially when the driver behind
them is bearing down on the bumper in a race to the office.
Ken Pietro of Detroit says he knows it irritates other drivers,
but that’s their problem.
“It’s just like, ‘hey, go around, go around,’ we’re in no hurry.”
Pietro says he doesn’t care, since he’s getting more than 52
miles per gallon. What’s your mileage? He didn’t even have
to buy a hybrid.
“People just can’t believe I’m getting that. You’ve got all the
newer Priuses and Honda Insights and all that. And these
people are shelling out 20 or 25 thousand dollars to get good
gas mileage with these hybrid vehicles. Which is fine, you
got the money to do it. That’s great, save the environment.
But I can do it in a $500 car and I’m getting better mileage
than them.”
And while you might complain about their slow driving, they
might just beat you home – they won’t have to make a pit
stop at the pump.

And you might think you already know what
that means – coast more, for example, or check your tires’ air pressure. But according to Ford Motor Company, if you really want to get better mileage, you need a trained coach in the passenger’s seat teaching you how to do

We’ve all heard we can improve our
gas mileage by changing our driving habits.
And you might think you already know what
that means – coast more, for example, or check
your tires’ air pressure. But according to
Ford Motor Company, if you really want to get
better mileage, you need a trained coach in
the passenger’s seat teaching you how to do
it. In the final part of our series
on saving gas, we sent reporter Rene Gutel
out to learn how to eco-drive:
(sound of car)
So I’m behind the wheel of my silver Mini Cooper and eco-driving instructor Mike Speck
is coaching me on how to get the best gas mileage I can, as safely as possible.
“Try to keep just a steady throttle input. You can see you are on and off the gas quite a
bit.”
We’re on suburban Phoenix roads at the beginning of rush hour. I drive a stick-shift and
one of the first lessons Speck teaches me is to shift gears a lot more quickly than I’m used
to.
Mike Speck: “And upshift.”
Rene Gutel: “Already?”
Speck: “And upshift.”
Gutel: “Oh! But we’re only going 30 miles an hour in fourth gear?”
Speck: “Yeah, it’s below 2000 RPM. The car is perfectly fine doing it.”
Speck is what they call a master eco-drive trainer at Pro-Formance Group of Phoenix.
Ford Motor Company recently teamed up with Pro-Formance to offer nearly 50 eco-
driving tests in Arizona. They studied the results which showed that by working with a
coach like Speck for just a few hours, drivers can improve their fuel economy by 24%.
The nuts and bolts of eco-driving are simple enough: Accelerate and break smoothly.
Slow down and watch your speed. Also, anticipate traffic signals as you’re going down
the road. But all this sounds way easier than it really is.
Speck: “Now we know there’s another slow left-hander coming up so off the gas.”
Gutel: “Okay, I’m off the gas.”
Speck: “And just let it coast around the corner.”
Gutel: Okay, I feel like you’re teaching me to drive my car all over again.
Speck: “I’m trying to do it as mellow as I can.”
That feeling – of going back to driver’s ed – is actually part of the experience of learning
to eco-drive.
Curt Magleby is the Director of Government Relations at Ford and he says to learn how
to do it right, you do need a coach.
“It’s not about tips and that’s what you’ll see on many websites throughout the US: tips
on how to be a better eco-driver. It’s got to be the hands-on coaching experience that
changes behavior.”
Ford is part of a new nationwide effort to encourage eco-driving. Magleby says there’s
talk of putting trained coaches at Ford dealerships.
“So when a person comes into a dealership and they’re considering the purchase of a
vehicle and we can talk to them about not only, here is the technology vehicle, here’s
what you can do, but you are a part of that equation.”
And down the line, Magleby says Ford might be pushing to have these techniques
become a part driver’s ed classes.
(sound of driving)
Speck: “You are accelerating very smoothly… very linearly. It’s very good!”
Gutel: “This is a different feel to driving. I feel like I’m coasting everywhere.”
Speck: “You are, and most people freak out about how much time they’re going to take.
When we validated the study, the average time increase was only 10%.”
Speck and I drive the same route three times during my eco-driving lessons. The first run
was the control, no tips from him at all, and I averaged 27 miles a gallon. But by the end
of the third run, we boosted that to 36 miles a gallon. Not bad, huh? Now if I can only do
that well on my own.

“Now try second. Well done! Go to third and just let it coast. Very well done.”
Tire experts say that your tire pressure does, in fact, effect your gas mileage (Photo by Karen Kelly)

Earlier this year John McCain
and Barack Obama traded jabs over how
important tire pressure was in saving
gas. Lester Graham reports the experts
say it does make a difference:
Tim Bent is the Environmental Affairs Director at Firestone Tires. He says you ought to
check your tire pressure.
“Many people don’t maintain their tires well enough. They don’t check their tire
pressure frequently enough. And that does result, not only in lower gas mileage, but
premature tire wear which could be a safety issue as well.”
Bent says you should check tire pressure once a month. How much of a difference can
it make?
“A couple p.s.i could result in a few percentage points in fuel mileage.”
And at today’s prices, that can add up at the pump.

Congress recently increased the Corporate Average
Fuel Economy standards, or CAFÉ standards. The new standard calls
for a car company’s entire fleet to average 35 miles per gallon
by 2020. But Mark Brush reports – there’s a problem with these
standards:
CAFÉ standards are based on fuel economy tests from the 1970s.
But the way people drive has changed a lot since then.
Engines are more powerful, people drive faster, and more cars use air conditioning.
That means these old tests don’t reflect the gas mileage we get today.
Experts say car companies are really averaging anywhere from 20 to 30% less than the
standards called for.
Jim Kliesch is with the Union of Concerned Scientists. He says the system should
change.
“If your representative is standing on Capitol Hill and telling you that they’ve raised
standards to 35 miles per gallon, you’d like to go out and buy a vehicle that can average
35 miles per gallon. Not one that averages 26, 27, 28 miles per gallon.”
There is a more accurate test available today.
Kliesch says it could be used to set CAFÉ standards if members of Congress require it.

With higher gas prices, SUV and light
truck owners are scrambling to trade in their
large cars for smaller more fuel efficient ones.
But, they’re shocked to learn how little they can
get. Lisa Ann Pinkerton reports:
The auto industry says, sales of new SUVs and light trucks have basically stalled and the
market is flooded with used models. That’s got used car dealerships across the country
offering owners about 20% less than their vehicles are worth.
Art Spinella, president of the auto research firm, CNW, says even at a steep discount,
Sport Utility Vehicles and light trucks are taking about a month longer to sell than they did a
year ago.
“If you need a sport utility for some reason, now is probably the best time to buy one. But
if you’re trying to sell a sport utility you may be better off just parking it and keeping it
until the market either turns around or the over supply that exists right now kind of dwindles down.”
Research shows a lot of SUV owners are deciding to not to drive them.

Emerging research is proving gasoline and jet
fuel don’t have to be made from petroleum. Lisa Ann
Pinkerton reports the next generation of fuel might
just grow on trees:
Researchers from the National Science Foundation say they’re using switchgrass
and agricultural waste, such as corn stalks, to make liquids very similar to gasoline and
jet fuel.
Spokesman John Regalbuto says, unlike ethanol, these new systems
don’t result in a 30% drop in mileage and the fuels can be distributed by today’s system.
“So you can use them in your car right now with no alteration of the engines. You
can ship them in pipelines, you
can use them in existing petroleum refineries.”
It might be 5 to 10 years before green gasoline or jet fuel make it to mass
production, but Regalbuto says the research published in this month’s Journal of
Chemistry & Sustainability shows that it can be done.

The energy bill signed by President Bush has a little bit of something to make almost
everyone happy. Lester Graham reports on some of the highlights:
The Energy Independence and Security Act is massive, but it can be boiled down to
just a few numbers. First, 35 miles per gallon by 2020… That’s when automakers
have to increase the fleet average by ten miles per gallon.
Second, 36 billion gallons by 2022. That’s when ethanol producers have to increase
production by a factor of five. And two-thirds has to come from sources other than
corn.
And these numbers – 100 watts, 60 watts – those kinds of incandescent lightbulbs
are to be phased out, replaced by more energy efficient lighting.
Most environmental groups can find something to like in the bill. Farmers like it for
the ethanol mandates. And big oil companies like the Act for what’s not in it:
billions of dollars of proposed taxes blocked by Republicans in the Senate.
If you plan to buy a new car or truck this
year, you might find some showrooms filled with
vehicles that run largely on ethanol instead of

If you plan to buy a new car or truck this
year, you might find some showrooms filled with
vehicles that run largely on ethanol instead of
gasoline. Car companies are pushing these corn-fueled vehicles as environmentally friendly.
Julie Grant takes a look at those claims:
More people are considering buying cleaner, more fuel-efficient
cars now that gas prices and global temperatures are on the rise. The gas-
electric hybrids made by Toyota and Honda are becoming popular. And
American car companies are also jumping on board and offering alternative-
powered vehicles.
General Motors CEO Rick Wagoner has put much of his company’s stock in
ethanol:
“At GM, we believe that the bio-fuel with the greatest potential to
displace petroleum-based fuels in the US is ethanol, and so we have
made a major commitment here to vehicles that can run on E85 ethanol.”
E85 is a blend that’s 85% ethanol with 15% gasoline. GM’s not the only company offering cars that run on them:
(Sound of vehicle introduction)
Angela Hines is from Green Bay, Wisconsin. She’s taking notes as she looks at one
flex fuel car. The E85 only matters to her if it’s going to save her a
few bucks:
“I drive anywhere from 80-200 miles
a day for work, so yeah, gas is important.”
Gui Derochers is looking at a Chevy Silverado pickup truck:
(Grant:) “Does it matter to you that it’s a flex fuel?”
“I think it’s a good thing… flex-fuel. Particularly, we know there are some ethanol plants in Michigan coming, right? Isn’t
that what flex fuel is? Ethanol?”
Derochers works on engines and transmissions:
“You have to remember, I work for Daimler-Chrysler. But we have flex fuel as well. It’s a good thing. It’s wonderful.”
But not everyone thinks the move toward ethanol-fueled cars is
wonderful. Tadeusz Patzek is a professor of civil and environmental
engineering at the University of California in Berkeley. He says
ethanol is not cheaper and it’s not any better for the environment than
regular gas.
Patzek says each gallon of ethanol burned might emit less greenhouse gas
into the air, but you have to burn more fuel to go the same distance:
“So, mile for mile, emissions of CO2 are exactly the same for gasoline as
they are for ethanol. Because they are proportional to the energy stored in
the fuel.”
When it comes to gas mileage, Patzek calls claims that ethanol is any
better then gasoline an imaginary economy… and he’s not alone. When Consumer Reports magazine tested a Chevy Tahoe that runs on gas mixed
with only ten percent ethanol, the truck got 14 miles per gallon. But
it got less than 11 miles per gallon when the ethanol content was
raised to 85%, as in E85. That’s a 27% drop in fuel economy with E85.
Consumer Reports concluded that to go the same distance, you wind up paying more than a dollar
extra per gallon on E85 then on regular
gas.
Patzek says it’s not a good deal for consumers or for the environment:
“You emit less because you have oxygen but you burn more, so it comes as a wash.”
Patzek says ethanol has other environmental costs. To grow the corn needed to make it, farmers have to use more fossil fuel-based fertilizers, tractor fuel, and then more fuel to truck the fuel to gas stations.
Even so, many scientists say ethanol still provides an energy benefit over fossil fuels and some auto engineers say ethanol cars
are just a stop-gap measure until a better technology comes along, but Patzek disagrees with that logic:
“So, you’re saying the following: why don’t we have a terribly bad
solution and call it a stop-gap solution because it’s politically
convenient. I’m saying is, if I’m an engineer, I have to, essentially, if I’m honest with myself and others, do I want a
better technological solution or do I want to say, let’s do probably the worst possible solution
that delays other solutions 10-15 years into the future… while the
world is running out of time?”
Patzek says the real reason American car companies are moving toward
vehicles that run on E85 is that the federal government rewards them
for it.
GM and the others get extra credit for meeting fuel efficiency
standards just for making cars that can run on E85, even if those cars
aren’t more fuel efficient.
Patzek knows he’s become unpopular among many farmers, engineers,
scientists and politicians who want easy answers. He wants people to
start reducing their energy-use rather than waiting for technological
magic bullets.

There’s going to be a change to the sticker that tells you the estimated gas mileage on a new vehicle. Dustin Dwyer reports that the US Environmental Protection Agency is rolling out the change in an effort to make the estimates more accurate:
The US EPA has used the same standard to test for gas mileage since 1984.
Bill Warem is with the Agency. He says the tests were only done at room temperature, they didn’t include using the air conditioner, and they didn’t include fast accelerations.
Warem says that hardly reflects real world driving conditions.
“Our concern with the methods that were previously used is they were not as accurate as they could be in estimating typical mileage that a consumer would expect to get from a new car that you purchase.”
Warem says the new way of testing for mileage will show up on stickers for 2008 vehicles.
He says the estimated miles-per-gallon for the average car is expected to drop by about 12%.
