Make Your Battery Last

Today's report from Muffler & Go is on vehicle batteries, why they die and what we can do to lengthen their life. Most of us have had a dead battery at one time or another. In fact, it would be very unusual if you hadn't. You may be surprised to learn that only 30 percent of Fenton vehicle batteries last for 48 months.

Now that's an average. How long a battery lasts depends on many factors. You may not know that one of the biggest factors is the temperature where you live and drive around in MI. You might suppose that cold weather was harder on batteries because it takes more power to crank a cold engine, but the opposite is actually true.

Batteries in very cold climates have a life expectancy of 51 months as opposed to 30 months in very warm climates. The reason is simple: batteries are chemically more active when they're hot than when they're cold.

A vehicle battery will actually start to discharge on its own within 24 hours in hot weather. It takes several days in cold weather. When batteries are left too long in a state of partial discharge, the discharged portion of the battery plates — for the lack of a better word — 'die.' Recharging the battery will not restore the dead part of the battery plate.

One of the big problems for the way most of us drive in the Fenton area is that our batteries are often partially discharged. The biggest job the battery does is to start the vehicle. It takes some time for the alternator to recharge the battery after starting. If you're driving short distances, especially if there are several starts and stops, your battery may not fully recharge.

Another issue is that vehicles are coming equipped with more and more electricity-hungry accessories like navigation systems, DVD players, CD and MP3 players, heated seats, heated steering wheels and so on. And we often plug in cell phones, computers and other gadgets. Combine that with short trips and it's no wonder that our batteries are partially discharged.

Experts say we can extend our battery life by topping off the charge periodically using a good quality battery charger. You may have heard these chargers referred to as 'trickle chargers.' They're attached to the battery and plugged into a wall outlet to slowly bring the battery up to full charge.

Now, there's some science involved with how fast a battery should be recharged. If you buy a cheap manual charger, you'll have to tend it. Frankly there is a learning curve on how to do it right and it requires much attention. A computer controlled charger – or smart charger – monitors the process and determines the appropriate rate of charge. And it even stops charging when it's fully charged. It costs more than the manual charger, but the automatic model is worth it.

The suggestion is to charge once a month in warm weather and once every three months in cold weather.

Another thing to avoid is deeply discharging your battery, something like running the headlights and stereo with the engine turned off. That'll take months off the battery life every time you do it.

Now, as we discussed, heat is hard on a battery. A dirty, greasy battery holds more heat. You can wipe off excess dirt with a paper towel or ask your service advisor at Muffler & Go to clean it for you. We can even test your battery and tell you if it's time to replace it.

Batteries are fairly expensive, so taking a few steps to make them last longer is well worth it. Of course, the battery will eventually need to be replaced. Always make sure you get a new battery that meets the factory specifications for your vehicle. If you feel you need more battery capacity than what came with your vehicle, talk with your service advisor at Muffler & Go about appropriate upgrades.

If you have a dead battery, be careful to inspect it before you jump start it. If the case is bulging, cracked or leaking, do not jump start it. Damaged batteries can explode or catch fire. And deeply discharged batteries can freeze. Do not jump start a frozen battery.

Differential Service at Muffler & Go

Here at AutoNetTV, we have national viewers, like your neighbors in Fenton, who write to us with questions or feedback. One common question we're asked is: "What is a differential and what does it do?" You may have been told by your Muffler & Go service advisor that your differential needs serviced, or it's seen it as an option up on the service menu. Differential service at Muffler & Go covers a lot of things, so let's first talk about what a differential does.

As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow on Fenton area roads. Differentials have gears in them that transfer the power from the drive train to your wheels - which is why they're often referred to as gear boxes. The gears need to be very strong to do this work, and they need to be properly protected so that they'll last.

All vehicles in Fenton have some form of differential. If you have a front-wheel drive car, your differential is sometimes called a transaxle and is located in the front. If you have rear-wheel drive, the differential is in the back of the car. Fenton auto owners with a four-wheel drive vehicle have a differential in the front and the back - and in the middle as well. The center differential adjusts for differences in speed between the front and rear wheels.

Differential fluid lubricates and cools the gears. Over time, the fluid can get dirty from bits of the gears grinding off. The additives that keep the fluid clean and protect the differential break down over time. So your vehicle manufacturer has scheduled intervals for you to have your differential fluid changed. Talk to your friendly and knowledgeable Muffler & Go service advisor if you are not sure about your recommended schedule.

Saving Lives in Fenton with Tire Pressure

All new passenger vehicles on our Fenton, MI, roads now have tire pressure monitoring systems – TPMS for short. They are designed to alert you if your tires are underinflated. Since they are fairly new, a lot of people have questions about them.

First off, the most important thing is that you still need to check your tire pressure every week – or at least every time you gas up. The TPMS system alert comes in when your tire is 20 percent below the factory recommendation. So if the recommended pressure is 34 pounds per square inch, the TPMS warning won't come on until the pressure is at 28 pounds. That's significantly underinflated, enough to raise safety concerns.

The worst is tire failure. A severely underinflated tire can overheat and fail. Also, handling degrades to the point that you may not be able to steer out of trouble. Also underinflated tires wear out faster and they waste fuel. So it's costly to not stay on top of proper inflation.

What's the practical value of the TPMS system? Well, it's twofold. First, it can alert you when your tire is losing pressure due to a puncture or a bent rim. That's an important warning that you might not have gotten until next time you gassed up.

The second is that we all occasionally forget to check our tire pressure. So it's a fail-safe system to let you know there's a problem brewing.

Other things can cause your TPMS system to go off. The system also monitors itself. The sensors that are mounted in the wheels have little batteries that send a signal to the monitor. The batteries go dead over time and the TPMS system will let you know. And the sensors could break. Also road salt from our MI roads can ruin them.

There's also a hassle factor that your Fenton, MI, tire center has to contend with. For example, when you have your tires rotated in Fenton, the TPMS system has to be re-calibrated so that it knows which tire is on which corner of the car. Same is true for when you have new tires or winter tires installed. Flat repairs, as well.

That takes extra time. And it requires the right equipment and training. Special – and expensive – tire change machines need to be used with some sensors. It's all complicated by the fact that there are a number of different TPMS systems in use so the tire professionals at Muffler & Go need equipment and training for each kind. Tire centers have had to raise the price of some of these basic services to offset their increased costs.

Also if you add custom wheels on your vehicle, you need to put in new TPMS sensors if your originals won't work on the new rims. If you don't your TPMS light will be on constantly and you won't have the benefit of the warning system.

All in all, the mandated TPMS systems will save lives, so they're worth the added hassle and expense.

Should Fenton Soccer Moms Follow the Severe Service Schedule?

So you take your vehicle in for maintenance and the pro at Muffler & Go tells you that you ought to change your oil more often. What? You followed the maintenance schedule – but you take a second look at that “severe service” schedule and see some of the following:

1. Most of your trips around Fenton are less than four miles/six and a half kilometers.
2. Most of your trips are less than 10 miles/16 km when outside MI temperatures are below freezing.
3. You don't do a lot of MI freeway driving, so you drive at low speeds most of the time.
4. You drive in an area with a lot of pollution, dust, dirt, mud or slush.
5. You frequently tow a trailer, haul heavy loads around Fenton or use a car-top carrier.
6. The weather in your area can get very hot or very cold.

Surprising, isn't it? Severe driving isn't quite what you'd envisioned.

Ask yourself: "Which auto service schedule should I follow?" For some of us, it's obvious. But for most of us, it's not an either/or question.

One way to decide how often to maintain your vehicle is to picture a line. On one end, imagine ideal driving conditions: year-round moderate MI temperatures, only freeway driving, all trips are longer than 4 miles/6.5 km and travel is always at a constant speed of 60 mph/97 kph. At the other end of the line, put the severe driving conditions. Now, stop and think about how you drive, where you live, where you go in MI and what you plan to do with your vehicle in the near future. Consider honestly where your driving fits on the line.

For example, if the regular maintenance schedule recommends an oil change every 5,000 miles/8,000 km, the severe schedule recommends 3,000 miles/5,000 km and you fall in the center of the driving conditions line, then 4,000 miles/6,600 km is a happy compromise. Just be honest. You don't want that happy compromise to turn into auto repairs.

Learning why our vehicles need more frequent service can also help us Fenton drivers determine a maintenance schedule. For example, fluids in your vehicle are depleted more rapidly the more heat there is in their environment. That heat can come from air temperatures, but also from the extra heat generated in the engine and transmission from stop-and-go driving. Towing a trailer or carrying heavy loads also generates more heat. So under these conditions, fluids must be replaced more often in order to retain their effectiveness.

Moisture naturally builds up inside of an engine because of the heating and cooling it constantly undergoes. When the engine is hot, moisture evaporates; when the engine is cool, moisture condenses. As long as the engine is getting hot enough to evaporate all of the moisture, your vehicle will remain healthy. But short trips don't allow for this and moisture can build up inside the engine. This moisture can lead to the formation of oil sludge, which in turn leads to clogged engine parts and damage.

In dusty or polluted Fenton area conditions, filters and fluids just get dirty more quickly. Talk with your service advisor at Muffler & Go regarding service schedules and which one is right for you. Good car care means taking care of problems before they become problems. And in order to do that, you need to know how often to take your vehicle in to Muffler & Go for service.
