Gas Prices Send Surge of Riders to Mass Transit
DENVER — With the price of gas approaching $4 a gallon, more commuters are abandoning their cars and taking the train or bus instead.Mass transit systems around the country are seeing standing-room-only crowds on bus lines where seats were once easy to come by. Parking lots at many bus and light rail stations are suddenly overflowing, with commuters in some towns risking a ticket or tow by parking on nearby grassy areas and in vacant lots.
“In almost every transit system I talk to, we’re seeing very high rates of growth the last few months,” said William W. Millar, president of the American Public Transportation Association.
Gas thieves pumped up by high gas prices
"Rising gas prices can motivate or force people to do these kind of thefts," said Calgary police spokesman Kevin Brookwell. "People who have never done this before will be driven by desperation because it is getting very expensive to drive a car."
As Gazprom Goes, So Goes Russia
Mr. Medvedev was sworn in as president on Wednesday, after winning the election in early March, and his ascent confirms that in today’s Russia, the line separating big business and the state is becoming so fine that it’s almost nonexistent.
Tensions Rise as Polar Bear Decision Looms
Steven C. Amstrup, the federal biologist who led an analysis last year concluding that the world’s polar bear population could shrink two thirds by 2050 under moderate projections for retreating summer sea ice, is once again in the field along Alaska’s Arctic coast, studying this year’s brood of cubs, yearlings and mothers.As the Bush administration rushes toward a court-ordered decision on whether the bears should gain threatened status under the Endangered Species Act, Dr. Amstrup is concerned anew by what he’s seeing, he said in an Alaska Public Radio interview a few days ago and in an email exchange Friday evening.
There was a time when we could count on Saudi Arabia to make up a shortfall in oil when something like Iraq came up. During the Gulf war Saudi Arabia boosted its production by 3.1 million barrels a day to make up for the 5.1 million barrels a day of Kuwaiti and Iraqi production that was taken off markets. Oil prices rose relatively little.Today, Saudi Arabia either refuses or can't increase its production. The peak oil Cassandras are convinced the Saudis can't. Saudi Arabia's mega fields like Ghawar are depleted, they say. And we'd better get used to gasoline at $4 a gallon and up.
But Crocker wasn't all bad news. He said that if we were to stabilize Iraq, and attract investors to the oil sector, Iraq could become the largest producer in the world, surpassing Saudi Arabia. Crocker didn't put it in terms this baldly, but he might as well have said: We keep an army in Iraq, and we go back to the days of cheap oil. Anyone can afford to drive an SUV if they want one.
Shell losing 30,000 barrels per day after Nigeria oil attacks
PORT HARCOURT, Nigeria (AFP) - Oil major Royal Dutch Shell said Saturday it was losing the equivalent of 30,000 barrels of crude oil per day because of recent attacks against its installations in Nigeria.The unrest in Nigeria, Africa's biggest oil producer, helped drive oil prices to a record high above 126 dollars on Friday, analysts said.
The loss in production translates to 409 million naira (2.24 million euros, 3.47 million dollars) in lost revenue every day, said Chidi Izuwah, a spokesman for the Shell Petroleum Production Company.
At $123 US a barrel, companies are highly motivated to find new oil reserves. The problem is many regions are running out of oil reserves.Norway's production has slumped by 25 per cent since its peak in 2001, Britain's by 43 per cent since its peak in 2000, and the giant Prudhoe Bay field in Alaska has dropped 65 per cent from its peak 20 years ago.
Mexico is also having trouble finding new oil to offset the decline of its largest oil field, Cantarell.
The huge offshore field peaked at over 2.2 million barrels a day in 2001. Production continues to fall and it now produces 1.22 million barrels a day.
Oil Refiners: Cheap for a Reason
Believe it or not, the business of buying crude oil and "cracking" it into gasoline, diesel, jet fuel and heating oil is losing money. It really is hard to believe, considering that everything this industry sells fetches 50% more than it did a year ago.But just like bakers who are staggering from the rising cost of flour or ice cream makers who are paying through the snout for milk and cream, refiners are squeezed by the rising cost of crude, whose price is rising much faster than the price of gasoline.
Libya to Reassess Italy Oil Deals Amid Government Row
Libya is reassessing some of its oil deals with Italian energy company Eni SpA (E) as tensions mount between the two nations following the new Italian government's high-level appointment of a right-wing politician who has angered the North African country in recent years.
Soaring fuel costs threaten to shut down Suriname fisheries
PARAMARIBO, Suriname; Increasing fuel costs are threatening to shut down fisheries in Suriname completely, with fish and shrimp trawlers kept in docks for over one month now, Prahlad Sewdien, president of the Suriname Seafood Association (SSA) has warned.He revealed that fishing companies can’t cope with the soaring costs of fuel, while there is also unfair competition in Surinamese waters from fishermen from Venezuela and Trinidad and Tobago who allegedly get fuel at a very competitive tariffs from their respective governments.
Spiking gas prices put towns in a pinch
SOUTH KINGSTOWN — For the first time, the town of South Kingstown expects to spend more than $300,000 on diesel and gasoline for the town’s fleet of vehicles. Town Manager Stephen A. Alfred estimated the town would spend $321,316 on vehicle fuel in the new fiscal year, up from a budgeted $271,397 this year and $249,338 in 2006.With fuel costs on the rise, Alfred thought he budgeted conservatively when he estimated gasoline at $3 a gallon. But with diesel prices at more than $4 a gallon and gasoline over $3.50 – and neither moving downward – town officials are looking for ways to keep costs in line before the budget year begins July 1.
No Relief in Sight for High Fertilizer Prices
Across the board, the price of synthetic fertilizer has gone through the roof. Dealers are reporting farmers are paying double or even triple the amount they paid last year for the same amount of fertilizer.
The False Lure of Lower Gas Prices
The transition to a low-petroleum future is a long-term undertaking that requires far-reaching changes in technology, capital investment and consumer behavior. Thus far, despite fits and starts, hopeful rhetoric, and thoughtful policy proposals, this bright future has eluded us.
High prices, shrinking wages & juicy profits
The first thing to know is that rising prices are not inevitable. Countries with planned—i.e., socialist—economies have kept prices remarkably stable, beginning with the Soviet Union, continuing with People’s China, until it opened up to the world capitalist market, and still in Cuba and the Democratic People’s Republic of Korea today. This is because prices there have been set not by a capitalist market but by the government—and food prices have always been set deliberately low so that no one goes hungry.
Ease off gas pedal -- live simply so others survive
Fuel costs will go down when the demand curve drops.But here's the rub: Those who can afford today's gas costs don't seem to care there are others who can't. The ones with the greatest ability to impact demand aren't willing to sacrifice.
People are still driving gas guzzlers unnecessarily, transporting children to several activities a week and commuting an hour to work. They're seemingly unfazed by how these actions affect others.
I'm glad there's a strong upper-middle and upper-class group of people relatively unaffected by gas prices. But it's selfishness when one's actions cause a hardship for others. Being wealthy doesn't earn anyone a pass for gluttony.
ANWR should be a part of solving energy crisis
Part of the response from the Democratic side of Congress after President Bush called on the body to approve legislation allowing oil and gas drilling in Alaska's Arctic National Wildlife Refuge is worth repeating just for the “wow” factor.It's no solution, goes a portion of the argument, because it would be more than 10 years before it could come into production.
Wow, if only President Bill Clinton hadn't vetoed ANWR exploration 13 years ago.
Many hands make light work of saving energy
SANDWICH, N.H. - Last weekend, some 30 men and women arrived at a neighbor's home in this mountainside community, prepared for a day of hard labor. Their pay would be a pot of coffee, slabs of cornbread, and a spread of roast turkey sandwiches.In days past, the end result might have been a barn. But in a twist on the traditional mutual aid event of a barn raising, the neighbors put up a solar-heated water system.
Indiana Agriculture Department reacts to ethanol myths
INDIANAPOLIS (WANE) - Pick up any publication today and you will see alarming claims about corn-ethanol driving the world into famine. Two years ago, the same publications were heralding ethanol as the savior of America's energy crisis. The truth is somewhere in between, and it is time for a calm, rational analysis of ethanol's contributions and limitations.The best way to begin a rational discussion is to address some of the biggest myths about ethanol.
At 15p a litre, home-brew biodiesel is fuel of the future
Since the law was relaxed to allow people to make 2,500 litres a year for their own use, most are working legally, but as the price of fuel rises inexorably, so criminal elements are moving in."There are wars going on in London to get the oil," said Tom Lasica, who runs Pure Fuels, London's largest refiner of vegetable oil. "Spanish and German companies are moving in to buy up British used vegetable oil. People are stealing it from each other and selling it abroad. We heard that one fish and chip shop in Southend was broken into just to steal the waste oil."
Oil Costs To Offset Stimulus Package
On the eve of President Bush's visit to Saudi Arabia, crude oil prices set a record for the fifth day in a row yesterday, eating into tax rebates being mailed to U.S. households and prompting FedEx to slash its quarterly earnings forecast by $100 million because of rising fuel costs.Since Congress and Bush unveiled an economic stimulus package Jan. 24, the price of the OPEC basket of crude oil has jumped by $32.51 a barrel, raising the cost of U.S. oil imports enough to offset the entire stimulus package over the course of the year.
As an American, I've taken for granted that I can get just about any food I want at the supermarket. In fact, the number of choices are dizzying. I never really thought about the tenuous chain between myself and my food. Less than 1% of the U.S. population is employed in agriculture, and 40% of these farmers are 55 or older. 1 The chain of transportation that brings goods to the stores is tenuous and depends on a few key railways and truck drivers. Supermarkets could experience spot shortages if the proposed trucker strike gains momentum or more drivers quit the business.
Two years ago, oil sold for just $70 per barrel. If you asked energy analysts back then what circumstances would lead to oil prices hitting $125 per barrel, they would have told you that only a catastrophe could lead to such unprecedented high oil prices such as a terrorist attack in the Saudi oil fields.
Mystery Indian analyst spooks world economy
WASHINGTON: They are calling him Arjun "Spike" Murti, but his real middle name is Narayana, the supreme manifestation of the Hindu God Vishnu.Supreme he is, in the oil world. The little known Indian analyst at Goldman Sachs has become a cause célèbre -- or a doomsday prophet -- for his forecasts about oil prices, based on what he calls the "super-spike" theory, predicated on rising demand for crude and limitations in refining capacity.
A new voice to Paine's cry of rebellion (review of Kevin Phillips' Bad Money: Reckless Finance, Failed Politics, and the Global Crisis of American Capitalism)
Beyond this double, double, toil and trouble financial brew, Phillips focuses on the increasing inevitability that global peak oil production is sooner rather than later. Phillips makes no bones about the matter that the American occupation of Iraq is about oil and states the obvious, "the attempt to make US energy policy from bomb bays and guided-missile cruisers misfired in 2003".
Energy at nexus of future, Yergin says
On a proposed "tax holiday" for consumers and the factors driving up oil prices:I think the calculation is it would save the average consumer $26.50. I think that what has driven this last wave of a surge in prices has been the fall of the dollar, the weakness in the U.S. economy, and a tremendous influx of investors into the energy markets, so I don't see what a tax holiday does. If you figure it out, it would really be a mini- mini-mini-rebate.
Coal is King: Demand worldwide has prices skyrocketing
WILLIAMSON, W.Va. – With coal prices spiking – and the demand for coal surging in overseas markets – local coal companies are experiencing tremendous growth.And coal — taken from the mountains of eastern Kentucky and southern West Virginia — is fueling economies worldwide.
How to Use the Strategic Petroleum Reserve
Over the last eight months, the Department of Energy purchased more than 10 million barrels of oil for the SPR as the price rose $40 to above $120. This is not sensible. It puts upward pressure on oil prices at the worst possible time. It is a waste of taxpayer money. It gives aid and comfort to unfriendly nations. And it is an insurance policy that, for the most part, is no longer needed.In fact, we should be selling oil from the SPR at $120. Doing so could be a powerful tool for U.S. energy policy.
Lebanese PM sends in army to tackle Hezbollah
BEIRUT, Lebanon - Lebanese Prime Minister Fuad Saniora on Saturday ordered the army to restore law and order across the country and remove gunmen from the streets.Saniora said Lebanese government can no longer accept that militant group Hezbollah freely hold on to its weapons.
In his first public remarks since fighting began on Wednesday, Saniora accused Hezbollah of carrying out an "armed coup" against Lebanese democracy.
U.K. Grangemouth Oil Refinery Blaze Extinguished
(Bloomberg) -- Firefighters extinguished a blaze at Ineos Group Holdings Plc's 200,000 barrel-a-day Grangemouth oil refinery in Scotland, which is still recovering from a strike last month, the Central Scotland Fire and Rescue Service said.
Shell pulls out of Iran gas deal
LONDON (Reuters) - Oil major Royal Dutch Shell has pulled out of a planned gas project in Iran, after coming under pressure not to participate from U.S. lawmakers who were concerned about Iran's nuclear programme.
Al Qaeda targeting Nigeria, police chief warns
LAGOS (Reuters) - Al Qaeda Islamist militants have renewed their threat to bomb targets in Nigeria, Africa's top oil producer, a newspaper reported on Saturday quoting the national police chief.The United States embassy in Nigeria said last September the country was at risk of "terrorist attack" and Osama bin Laden once named the world's eighth biggest oil exporter as ripe for jihad or Islamic holy war.
China says 3 of its construction workers abducted in Nigeria have been freed
BEIJING: Three Chinese construction workers who were abducted in southern Nigeria's troubled oil region have been released, the government said Saturday.The Chinese were freed Friday after three days in captivity, Foreign Ministry spokesman Qin Gang said in a statement carried by the official Xinhua News Agency. It gave no details of how they were released.
Russian roulette on the pipelines
The chilly front of the Cold War is being replaced with a heating battle, as demand for gas increases along with the price. Russian giant Gazprom appears to have the upper hand in this power struggle but eastern European countries have weapons of their own to keep fuel prices at the low levels they have become accustomed to.
Venezuela, China to Create Joint Venture to Supply New Refinery
(Bloomberg) -- Venezuela agreed with China, the world's fastest-growing major economy, to form a joint venture that will produce oil in Venezuela's Orinoco Belt to supply a new 400,000 barrel-a-day refinery they will build in China.
Brazilian President Luiz Inacio Lula da Silva believes his nation wants to join Opec to help bring down oil prices, a leading German weekly quoted him as saying Friday. Silva said in the interview published in Der Spiegel news magazine that his nation plans to exploit massive deep-water oil reserves discovered near Rio de Janeiro. “Then Brazil will become a major oil exporter,” Silva said in an advance copy of the interview to be published Saturday. “We want to join Opec and to try to make oil cheaper.”
An Energy Policy That Makes Sense, Revisited
On April 4 (2008) I published my first energy policy here on Seeking Alpha. Oil was around $100/barrel. Roughly one month later, oil is up another 20% and now over $120/barrel; the US dollar is dropping like a rock; the S& P500 has done nothing in years, and inflation, food and otherwise, is high and rising. CEOs of major oil companies took the unprecedented step to publicly say at the World Economic Forum in Davos, Switzerland that worldwide oil supply will not keep up with worldwide oil demand by the year 2015. That is only 7 years from now. If oil prices are $120/barrel today (while oil supply and demand are balanced), what will prices be in 2015? Regardless, it is well past the time to take action. Yet still no word from the President and Congress on a real energy policy to prepare and protect America from the realities of peak oil. Why?
Oil Lobby Reaches Out to Citizens Peeved at the Pump
Faced with a national outcry over the high price of gasoline and soaring profits for energy companies, the oil and gas industry is waging an unusually pricey campaign to burnish its image.The American Petroleum Institute, the industry's main lobby, has embarked on a multiyear, multimedia, multimillion-dollar campaign, which includes advertising in the nation's largest newspapers, news conferences in many state capitals and trips for bloggers out to drilling platforms at sea.
Rising fuel prices are a driving force for change - away from autos
Only 7% of people in Los Angeles took public transportation to work in 2006, the last year for which figures are available, while 2.8% walked, 1.4% took a cab or motorcycled and 0.6% bicycled, according to the Southern California Assn. of Governments.But people are cutting back in a million little ways, and even in the Los Angeles area they're cutting back on driving. Interest in cycling is growing, gasoline consumption is down and bus and light-rail ridership is up.



How to Use the Strategic Petroleum Reserve
I just finished writing an article on that:
Stop Filling the SPR?
The truth is, the rate of fill is about 0.05% of the world's daily oil consumption. That's just noise. You could save more oil by simply having full-service gas stations check the air pressure of the tires on every car that stops by - yet I don't see anyone calling for that.
My conclusion is that since it is already almost full, yet the fill rate is so slow, it really isn't going to make any difference either way. But the suckers who want to sell oil from the SPR at current prices obviously think oil prices long-term are going down. Let them bet their own money on that.
Probably because there aren't any full service stations. Except in New Jersey and other places where they are mandated by law.
Honestly, I haven't seen a full-service station for years.
There are a few places. I think that's the law in Oregon as well, and I have run into it at places in Europe.
But, even without that, there could be a campaign reminding people to check the air when they fill up, while making air hoses available at the pumps (instead of tucked off in a corner).
Here in Ontario media coverage of fuel prices is now a daily feature. Most of the local TV coverage regularily includes tips on how to save and tire pressure is always included as well as driving style tips. However whenever I visit Canadian Tire stores invariably the housewares and do-dads sections are the busiest with very little traffic in the automotive sections. I think a lot of people don't even know the car has tires, let alone that there is air in them.
Charity groups could check the air pressure for a free-will donation. Like some of them do with car washes.
Hey, I was about to post that! Yes, it would be a lot easier than washing cars and could even be done by old farts like me.
That will never happen. It requires gas station owners to invest in new infrastructure, when a lot of them are hurting from the high prices worse than their customers.
Besides, checking tire pressure is best done before you start driving, not at the gas station when you may have been driving for awhile.
What do you think of the WSJ's idea that we should sell oil from the SPR?
It requires gas station owners to invest in new infrastructure...
I think most of them already have the compressors. It's a matter of education and access.
What do you think of the WSJ's idea that we should sell oil from the SPR?
It's kind of like running without insurance. It's a great way to save money - provided I don't have an accident.
If one had some kind of knowledge that oil would definitely be lower in the future - and the guy advocating that clearly felt that way - then it would make sense. But if you think oil is going much higher, then it would be stupid. Remember, people have been calling for the SPR to be tapped since oil hit $20. Imagine the situation we would be in now - $120 oil and an empty SPR - if those calls had been heeded.
They have the compressors, but as you note, there's usually one, off in a corner, away from the pumps. Having them at the pump, as you suggest, would force stations to have more than one.
Yeah, but the non-peak oil aware won't really care about that. They just want to know if it will work. (And note they are in favor of maintaining a certain minimum level in the SPR, so we'd never be entirely without insurance.)
And we'd be able to fill up again, once oil drops below $40/barrel!
I think that we need the SPR. Remember New Orleans after the flood. A major city without gasoline will look the same in a few days.
That's really the perfect comeback for people like us to use. Of course, the government can't use it lest it cause panic. This administration probably even has reason to think oil could soon spike, and they can't say that either.
It's the strategic reserve, not the "cheapskate" reserve anyhow.
Maybe our fine President *knows* there will be a problem with oil supply in the near future...
Like when we invade Iran?
In which case the reserve would probably be used to make fuel for military vehicles and aircraft. In the event of an attack on Iran, fuel shortages would last a lot longer then 90 days, and the US military is one of the world's largest users of oil...during WWII, people didn't drive unless they got the right permit...everyone else walked or took a bus.
As I see it, the SPR isn't there so we can keep driving to the Dairy Queen in our SUVs -- it's there for the military, and emergency services, and health care, in the event of a national crisis. I don't think selling oil out of the SPR would make much of a difference in oil prices -- we here in the U.S. are no longer driving the bus, when it comes to global oil demand and consumption.
The DOE wants to do this with the SPR:
/
Iran has 20 million barrels of heavy oil in storage in tankers. I suspect that they would be willing to make a one time deal at a good price (payable in euros through Swiss bank). This would effectively fill our SPR (701.x to 721.x million barrels) and allow us to bomb them.
Best Hopes for Rational Behavior :-(
Alan
Around South Florida even 'free air' regardless of where it is located is scarce. Most self serves with "convenience" stores have the air and water off to the side AND for seventy-five cents!
Pete
Not only are tucked off in a corner, but they are usually coin operated. Last week I needed one because of a slow leak, I had to ask at the pay counter. At least they turned it on for me for free, as I am a frequent customer. Otherwise the machine wanted $.75 for the honor of using it.
Wow, I never heard of such a thing. I thought you always had to pay. It would never even occur to me to ask to use it free.
Why don't we just use handpumps? I have a $7.50 pump I bought a few years back, and a nice round airpressure gauge. You should always have both in your car at all times, anyway! It ain't THAT hard!
I purchased emergency gizmos for both our cars that will inflate a tire and run off the car battery. They also have a built-in flashlight and warning flashers. They cost about $20, I think (made in China, of course). I've been looking for a manual foot pump, but I haven't found one yet (admittedly, I haven't been looking very hard or in the right places yet).
I've been looking for a manual foot pump,
Visit any bike sections in a tarket/kmart/mal-wart big box store. Downside - they are flimsy.
At least in California, state law now requires gas stations to provide free air to customers. If they have a pay machine you can ask the clerk and he'll give you a token or a quarter. The law was passed a year or two ago to encourage energy efficiency and safety.
You find full service throughout Oregon. The law says you can't pump your own gas.
On the other hand, perhaps we should take some responsibility here and do the checking of tire pressure ourselves?
I covered this in another article I recently wrote. In that essay, I posted the following excerpts from a recent story on Yahoo:
1.2 billion gallons is three times what we put in the SPR in the past year - but have you heard one government official talking about an intiative to air up our tires?
I'd be interested to know when that study was done. It can be difficult to keep tires at the right pressure when the seasons are changing. In April and May around here, it's not unusual for it be 90F one day and 30F the next.
And yes, I've heard government officials talking about tire pressure. They even passed a law about it.
And yes, I've heard government officials talking about tire pressure. They even passed a law about it.
That's a new one on me. Can someone confirm that the 2008s have these sensors?
My daughter's 2007 Toyota Pruis has the tire pressure lights.
Appearantly the federal government has passed
legislation
that mandates TPMS (tire pressure monitoring system) on every vehicle under 10,000 lbs GVWR starting September 2007 relating to Firestone and other tire safety issue.
Some flap about tampering and installing custom wheels.
The cheap and dirty way to do this has always been to count 'triggers' of the ABS sensors and alert when one tire turned in too many revolutions over it's counterparts. The problem here was it took the brain awhile to decide if it was really happening. Don't know if the new law mandates the smart in-the-wheel variety, (which address the fuel mileage issue more directly rather than just safety) probably not.
We just got in new Chevys. The Impala I drove read out each tire pressure as I drove, along with the running instantaneous gas mileage.
Hi Robert,
I have a tendency to overinflate my tires in an effort to improve fuel economy and over the years I'm reasonably sure I've blown at least two as a result. The tire pressure monitoring system on my car shows the real-time pressure of all four, in kiloPascals or psi, as well as the condition of the spare. If one or more tires fall out of range, it flashes a warning and the readings of affected tire(s) blink on the display. This system has been triggered several times in the six years I've owned this vehicle, typically when the weather turns sharply warmer or in extended high-speed driving. For me, it offers considerable peace of mind, added convenience and greater safety, plus it has protected me from expensive loss (you don't want to replace a P255/45ZR-18 before its time and/or an alloy rim if you can possibly avoid it). If this isn't standard equipment on all vehicles, it really should be -- that and side-impact air bags.
Cheers,
Paul
Over or under inflated tires suffer enhanced, and uneven wear. The cost to the motorist of premature replacement can be considerable.
Hi EoS,
That's true. In years past, I use to fill my tires to their maximum rating specified by the tyre manufacturer but, as you know, 35 psi at -20C is altogether different at +20C. In Atlantic Canada, temperatures can swing from one extreme to the other all in the same week, so what's perfectly fine one day can be potentially disastrous the next. The TPMS has made me much more aware of this fact and taught me not to push the boundaries quite as hard. Now, I don't worry about day-to-day changes in my vehicle's tire pressure for the simple fact that my car monitors it for me.
Cheers,
Paul
Our 2006 Prius has the sensors. They aren't very accurate, however (at least in the '06 models). They are useful to warn of impending problems, not to make sure they're filled to optimum pressure.
Leanan -
The effect of these day-to-day temperature fluctuations on tire pressure tend to average out, but on the whole I think it is safe to conclude that most cars have underinflated tires - simply because there are inherent very slow leaks coupled with the fact that most motorists tend to ignore tire pressure. Also, remember that it is the differences in absolute temperature that determines pressure differences, so the difference in pressure resulting from a drop in temperature from 90F to 30F is not as great as it would at first appear.
If you check you tire pressure once a month, you should be pretty close to maintaining the proper pressure most of the time. It is very important to be extra diligent about this at the onset of Winter.
I personally find using a service station air hose both inconvenient and slightly dangerous (almost got run over by a car pulling out while bending over putting air in a tire), so I bought a nice little air pump ($49 at Peb Boys) and do it myself. It's probably already paid for itself.
I became a little compulsive about tire pressure as the result of having owned two rear-engined cars, a '66 Corvair and a '68 Beetle. The handling of a rear-engined car is extremely sensitive to front-to-rear relative tire pressure, so neglecting tire pressure with such cars is at one's peril.
I have a little air pump, too. It was $80 at Brookstone. You plug it into the ciga
