Car companies want more gas additives
The Kansas City Star
“Frankly, we didn't want too much
input.”
Andrew Buczynsky of GM, about the new fuel standards
Some members of Big Auto and Big Oil are at loggerheads over the
quality of gasoline pumped into automobiles in this country.
A consortium of major automakers, citing persistent repair
problems and troubling product tests, recently concluded that the quality of
U.S. gasoline varies widely and often doesn't burn clean enough to keep engines
running smoothly.
And now, in a move that is roiling much of the oil industry,
General Motors, Honda, Toyota and BMW have banded together to push a new
industry fuel standard. If that standard is adopted, it will increase levels of
gasoline additives that prevent deposits on intake valves and fuel injectors
that foul engines and affect performance, emissions and fuel economy.
The new class of fuel, dubbed “Top Tier Detergent Gasoline,” is a
voluntary standard that exceeds the current standard set by the Environmental
Protection Agency. But gas marketers, under pressure from automakers, may find
it hard to ignore, since it could put them at a competitive disadvantage.
Gasoline sold by QuikTrip — the area's biggest fuel marketer —
already meets the Top Tier criteria. ChevronTexaco, which has no retail
presence in the area, also has adopted the standard. Other companies, including
Shell Oil, have plans to meet the new standard.
The push comes as the automakers say they are seeing persistent
problems such as clogged fuel injectors and as they begin to introduce a new
generation of vehicles engineered to meet tougher environmental standards.
Those new vehicles especially will need fuel with more additives.
The automakers are buttressing their case with an industry
analysis that tested fuel samples taken from cities across the country —
including Kansas City. It shows detergent levels in gasoline dropping nearly 50
percent since 1996.
“We've just felt for a long time that gasoline detergency was not
at a proper level,” said Andrew Buczynsky, a GM fuel engineer.
The American Petroleum Institute, an association that represents
the oil industry, said it was surprised and disappointed by the automakers'
decision to push Top Tier without seeking the advice of oil companies. The
association has sent a letter to the automakers seeking the data used to back
their allegations and offering to conduct additional gasoline tests.
“At this point, we're waiting for a response,” said Ed Murphy,
downstream manager for the American Petroleum Institute.
Top Tier is intended to give motorists greater comfort that the
fuel they buy has sufficient cleaning ability. Experts say the cost of adding
the needed detergents is a fraction of a cent per gallon.
The controversy over the quality of gasoline challenges the widely
held belief that all gasoline is about the same.
The auto industry analysis reveals that different brands have
different detergent levels. And while all gasoline is thought to at least meet
the EPA's minimum standard for detergents, the automakers say that level is
often insufficient to keep engines clean.
Although the cost of introducing Top Tier gasoline would be
minimal for consumers, it could threaten how some oil companies market premium
fuel, which costs about 20 cents more per gallon than regular gas.
Premium accounts for about 15 percent of gasoline sales, but
experts estimate that demand for premium would fall to about 5 percent if only
cars that needed the extra octane used premium.
Some oil companies have sought to increase sales of premium by
touting that it contains a higher level of detergents. But Top Tier will blur
that advantage, since all grades, including regular, will have to meet the new
standard if a marketer wants to participate in the program.
So far, Top Tier gas has received scant attention. But that is
expected to change as it is included in gasoline marketing.
Automakers plan to publicize a list of gas companies offering the
fuel and are developing a Top Tier logo for gas pumps. They have created a Web
site at www.toptiergas. com.
Groups such as the A A A are beginning to hear about the new fuel
standard. The automobile association is currently considering whether to
support the Top Tier program.
“We have the same basic concerns that the automakers have,” said
Michael Hecht, manager of technical services for AAA Auto Club of Missouri. “We
support it.”
Questions about fuel quality once seemed settled.
In the 1980s, additives became an issue when fuel injection became
popular in new cars and trucks. The injectors often became clogged, and the
problem was traced to gasoline with insufficient detergent additives.
Automakers began to publish “good gas” lists. The lists were
eventually dropped at the urging of some gas marketers, but by then the problem
had eased.
Still, some gas companies weren't using detergents and, in a move
supported by the auto industry, federal regulators mandated specific levels of
the additives. The EPA finalized the regulation in 1997.
But something happened after the new regulation took effect: The
amount of detergents in the nation's gas supply dropped sharply.
The Alliance for Automobile Manufacturers twice a year takes
gasoline samples in 26 U.S. cities — including Kansas City. One of the tests is
for “unwashed gum,” which is an indicator of the amount of detergents in
gasoline.
In the winter following the EPA standard going into effect,
according to AAM tests, unwashed gum levels in regular gas dropped more than 20
percent. By 2002, gum levels had declined about 50 percent. Although recent
tests show slightly higher levels, they are still low.
Joe Colucci, a retired director of research and development at GM
who now operates Automotive Fuels Consulting, said reducing detergent additives
to the EPA regulation level was seen by some companies as a way to reduce
costs. Although detergents cost only a fraction of a cent per gallon, it adds
up to an enormous sum because of the huge volume of gas sold.
“They would say to themselves, ‘We'll meet the letter of the law,'
and that's what has happened with much of the gasoline,” Colucci said.
By 2002, the automakers say repair records suggested that the EPA
standard for detergents wasn't high enough. They approached the EPA about
increasing gasoline detergents, but say they were rebuffed.
“We would have liked to have had some leadership from the EPA, but
we just haven't been able to get that,” said John Cabaniss, a director of
engineering at the International Auto Manufacturers Association.
An EPA spokesman said the agency was unaware of the industry
attempt to improve the fuel standard. He said the agency's program mandates
that certified detergents be used and in what amounts.
“The program is working well,” said EPA spokesman David Ryan.
But questions about the EPA standard appear to have been the focus
of growing concern at industry forums, such as an vehicle emissions conference
in Chattanooga, Tenn., late last year attended by oil and auto companies.
The Alliance of Automobile Manufacturers described “continuing
problems from inadequate additives use” and said the EPA needs to update its
regulations, according to information presented at the conference. Another
speaker said he was seeing problems with fuel injector fouling even when the
fuel met EPA requirements.
Some oil companies question the standard as well.
Shell Oil estimates that 60 percent of the fuel sold in the United
States is at or near the “EPA minimum level of detergency” and says that has
caused problems in some cars.
“We have measured significant deposit buildup in certain vehicles
in as little as 5,000 miles,” Shell stated in one document.
Early this year, GM approached Honda, Toyota and BMW to join in an
effort to improve gasoline detergent levels. GM believed that an organized
group rather than a lone automaker would show the seriousness of the issue.
The move came at a time when automakers were beginning to produce
vehicles to meet the EPA's “Tier 2” environmental standards for reduced
emissions. Such vehicles need quality fuel to avoid reduced performance.
“We feel high detergency is preferable,” said Douglas McGregor, an
emissions compliance engineer for BMW.
In early April, the American Petroleum Institute held a meeting in
Detroit for the oil and auto industries. A week before the meeting, the
association received a letter stating that the four automakers would be
discussing the Top Tier program.
“We were disappointed,” said Murphy of the petroleum institute,
adding that his group didn't know Top Tier was even in the works before
receiving the letter.
The oil industry wasn't given an opportunity to give its advice,
Murphy said, adding that a new fuel standard typically involves cooperation
between the industries.
But collaboration is unlikely. The automakers say they have
previously reached out to the oil industry with concerns, but nothing happened.
As a result, the automakers decided to proceed unilaterally with a new fuel
standard.
“Frankly, we didn't want too much input,” said Buczynsky, of GM.
“Because when we have, it would always drop down to the bare minimum.”
The Top Tier standard was modeled after California's fuel quality
regulations, which allow half the deposits on intake valves that the federal
rules permit. Buczynsky said the amount of detergents in Top Tier-certified
gasoline will be two to three times the current EPA standard.
While some brands of gas currently have more than the EPA
standard, according to the auto industry's testing, there are many at the minimum
level of detergent.
A gasoline marketer who wants to meet the Top Tier standard must
do it for all grades — not just premium — and make it available at all
stations.
While meeting the standard will require testing, automakers say
they strive to minimize costs. Despite the additional detergents, the cost is
expected to be a fraction of a cent per gallon.
But the Society of Independent Gas Marketers of America fears that
any additional costs could prevent some members from offering the Top Tier gas.
“A fraction of a cent can be a substantial part of your profit,”
said Tom Osborne, a spokesman for the group.
The independent marketers group, however, has invited a GM
representative to address its members. The society's staff also has been
instructed to begin helping members who want to participate in the Top Tier
program. One of its major members, QuikTrip, already has qualified for the Top
Tier program.
More major brands are expected to make similar announcements so
competitors don't get an edge. Shell plans to have all grades of its gas
certified Top Tier this summer.
