Your Monday Maintenance Tip: Avoiding Potholes

Potholes destroy tires, and the price of tires is rising sharply due to a supply shortage of natural rubber (yes, it still comes from trees, mostly in southeast Asia) and increasing demand from China, where car ownership is undergoing double-digit growth. Petroleum is also used in tire manufacturing, adding further to cost volatility. Blow out just one tire on one pothole and expect to pay out more – one major tire manufacturer increased prices three times in 2011 alone.

 

Damage from potholes doesn’t stop at tires. In a blink of the eye, you can experience $1000 of damage, possibly more, when your car hits a pothole – it’s possible to impair your car’s shock absorbers, suspension system, struts, rims and alignment as well. According to the American Association of State Highway and Transportation Officials, the average additional vehicle operating costs due to rough roads in 2007 was $400, with higher costs experienced in places including Baltimore ($589), Concord, NH ($656), Dallas-Fort Worth ($512), Los Angeles ($746), New Orleans ($622), New York-Newark ($638), Oklahoma City ($631), San Francisco-Oakland ($705) and Tulsa ($703). Deteriorating roads and general inflation since 2007 likely pushed these costs higher.

But there are things you can do before, during and after hitting a pothole. A preventive strategy is more about preparation, driving skills and reacting appropriately when a pothole sneaks up to surprise you. We suggest you approach it on three fronts, as follows.

Adopt smarter driving practices

You can reduce damage with vehicle preparation and driving with good sense:

• Check your tire pressure to keep it at the tire manufacturer’s recommendation. If a tire is too soft, it handles poorly and in a sudden bump may rupture if the wheel rims pinch it against the jagged edge of a pothole. Over-inflated tires are more susceptible to damage as well.
• Have a clean windshield! Your field of vision is critical.
• Observe the traffic ahead of you – if other cars are swerving and stopping, it’s because of a problem in the road.
• Beware of puddles – what might look like a little surface water might have a nasty, deep and sharp-edged pothole lurking below.
• Reduce your speed on roads that are prone to potholes. Slower hits generally involve less damage, a simple matter of physics.
• Stay focused and pay attention to the amount of traffic in front, behind and alongside you. You might be able to avoid potholes but do not want to cause an accident while doing so.

React quickly, intelligently when a pothole is upon you

Assuming you drive defensively – and do not tailgate, which restricts your ability to anticipate potholes or sudden braking by the vehicle in front of you – here is what to do if you are just about to hit a pothole:

• Brake only lightly, if at all. And do something counterintuitive by letting off on the brakes entirely the moment before impact. Clamping down on your brakes at higher speeds not only tempts rear-end collisions but also compresses the front-end suspension system, increasing the damage.
• Hard braking can actually cause greater contact between the tire and the pothole where it might otherwise glide over it.
• Do not swerve in a last ditch attempt to avoid the pothole. Aside from creating a hazard for vehicles immediately behind and beside you, you risk hitting the pothole on an oblique angle, which can cause more damage to the tire, wheel rim and alignment than if you hit it perpendicularly.

Reduce the damage in the aftermath

Post-impact, the right moves can at least limit the extent of the damage:

• Immediately pay attention to whether or not you have a flat tire. If so, minimize how much you drive on it, pull off the road as soon as you can do so safely where you can change the tire to your spare. This will minimize the damage to your wheel rim.
• Even without a flat, there may be preliminary damage. At your next stop, check tire rims to see if they were bent, if there is visible cord material or bulging. This could fail later while driving.
• Note if your car pulls to one side without corrective steering. This suggests the wheels are out of alignment and need mechanical attention.

In most municipalities, you can and should report potholes to the streets department – use a smartphone app such as SeeClickFix or SaveMyTire.com, or the local 3-1-1 or other call-in line. You might also be compensated for your loses if that pothole was reported previously and left unfixed, however rules for this are determined on a city, township or county level.

GM Shows Chevrolet EN-V 2.0 Mobility Concept Vehicle

BEIJING – General Motors showed the company’s vision of the Chevrolet EN-V 2.0 concept at Auto China 2012 today. It is an evolved design of the company’s revolutionary mobility concept revealed at World Expo 2010 Shanghai.

“Our designers and engineers are exploring a range of options for turning the EN-V concept into a reality,” said Kevin Wale, president and managing director of the GM China Group. “The EN-V 2.0 concept would use technologies such as the mobility Internet, electrification and telematics to help change the automotive landscape and ensure a sustainable future for our industry,”  

The original EN-V (Electric Networked-Vehicle) concept was a centerpiece of the SAIC-GM Pavilion at World Expo 2010 Shanghai. The two-seat electric vehicle pioneered a new automobile DNA based on the convergence of electrification and connectivity. It was developed to show the possibilities for alleviating concerns surrounding traffic congestion, parking availability, air quality and affordability for tomorrow’s cities.

The EN-V 2.0 concept adds features that consumers demand such as in-vehicle climate control and personal storage space. In addition, it would be capable of driving in all weather and city road conditions.

GM expects to use EN-V 2.0 prototype models in pilot studies throughout China.

Your Monday Maintenance Tip: Oil Changes

An oil and filter change involves draining out the old motor oil and replacing it with fresh, new motor oil. The oil filter also gets replaced at the same time.

Should I do this service when it's recommended?

In general, yes. Changing your vehicle's oil is one of the most important things you can do to avoid bringing large bags of money to your mechanic later on.

However, there's a lot of controversy about exactly when engine oil gets old and how often it should be replaced with new oil. Because there are many factors at work -- how you drive, the condition and age of the engine, the external environment you drive in, and stop-and-go versus highway driving -- it's an inexact science. Owner's manual recommendations for oil and filter changes vary from 3,000 to 10,000 miles.

We recommend that you change your oil and filter every 5,000 miles. That's our best estimate. It may be too soon for many people and too late for a few, but for the vast majority, 5,000-mile oil changes will help your engine last to a ripe, old age.

You may want to consider changing your oil more frequently if:

• You drive like a knucklehead: jackrabbit starts, heavy acceleration or high-speed driving
• You live where the climate is extremely hot or cold
• You often drive on dirt roads
• Your engine is old and burns oil
• You frequently carry heavy loads (several mothers-in-law or other cargo)

Why do I have to do this?

Oil undergoes thermal breakdown due to high operating temperature. When this occurs, the oil becomes less effective as a lubricant. And without a good lubricant (read: expensive), parts of the engine rub together and wear each other out.

Oil also contains additives that have the ability to neutralize acids. Over time, these additives get used up and stop being effective.

Finally, oil can absorb water, dust and combustion byproducts and also hold them in suspension. Eventually, the oil gets saturated with this stuff and can't absorb any more. Then that stuff remains in the engine and can cause corrosion.

What happens if I don't do this?

Your engine won't last as long as it could. Oil serves many crucial functions, and clean oil performs those functions better than dirty oil. Oil is relatively cheap, and changing your oil every 5,000 miles is a very cheap insurance policy against major repairs down the road.

Chevrolet Goes to Bat to Help Refurbish Detroit Ball Field

DETROIT – Chevrolet employees and volunteers – including Detroit Tigers mascot PAWS -- pitched in to help polish a diamond into a gleaming jewel Thursday, at the Jayne Field youth baseball complex on Detroit’s east side.

Chevrolet’s baseball roots run deep. In addition to being the Official Vehicle of Major League Baseball™, Chevrolet supports youth baseball initiatives across the country through the Chevrolet Youth Baseball and Diamonds and Dreams programs.

Since 2006, participating dealers in the Chevrolet Youth Baseball program have helped raise more than $13 million for equipment and other team needs; sponsored more than 500 youth clinics; reached more than 3 million young people and helped raise money to fund more than 2,000 park improvements. This year, more than 1,600 Chevrolet dealers are involved.

The Detroit project is coordinated in partnership with Think Detroit PAL, which operates the largest youth baseball program in the city; as well as the Detroit Recreation Department and the Detroit Economic Growth Corporation.

Chevrolet employees and volunteers cleaned, pulled weeds and painted the dugout and bleacher areas at Field No. 4 in preparation for a professional field makeover by Ripken Design and Scotts Miracle-Gro. The field will be refurbished in time to kick off the 2012 youth baseball season.

“As a major supporter of youth baseball across the country, Chevrolet is looking forward to giving young baseball players in our hometown of Detroit a field they can be proud to play on,” said Chris Perry, vice president, global Chevrolet marketing.

Think Detroit PAL uses the Jayne Field complex under an agreement with the City of Detroit, which owns the park. Last year, 1,400 young people played on about 100 teams in PAL baseball leagues. In total, Think Detroit PAL sports programs serve 10,000 city youth each year.

“We are excited about working with Chevrolet and the City of Detroit to enhance a great baseball park where our kids can learn the positive lessons that come from being part of a sports team,” said Tim Richey, Think Detroit PAL CEO.

Chevrolet began the Diamonds and Dreams program in 2010 to help provide young ball players with an opportunity to play on a “dream” baseball field in their hometown.

Later this month, Chevrolet will announce its 2012 participation at www.chevybaseball.com. Since this online and mobile grassroots promotion began, Diamonds and Dreams has awarded over 25 baseball field makeovers across the United States in partnership with Ripken Design and Scotts Miracle-Gro; and received more than 140,000 entries.

Your Monday Maintenance Tip: Keeping Your Car in Shape

Keep Your Engine Properly Tuned

Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent, though results vary based on the kind of repair and how well it is done.

Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.

Keep Tires Properly Inflated

You can improve your gas mileage by up to 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.3 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.

The proper tire pressure for your vehicle is usually found on a sticker in the driver's side door jamb or the glove box and in your owner's manual. Do not use the maximum pressure printed on the tire's sidewall.

Use the Recommended Grade of Motor Oil

You can improve your gas mileage by 1–2 percent by using the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1–2 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1–1.5 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.
