Should Herndon Soccer Moms Follow the Severe Service Schedule?

So you take your vehicle in for maintenance and the pro at McLearen Shell 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 Herndon are less than four miles/six and a half kilometers.
2. Most of your trips are less than 10 miles/16 km when outside VA temperatures are below freezing.
3. You don't do a lot of VA 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 Herndon 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 VA 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 VA 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 Herndon 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 Herndon area conditions, filters and fluids just get dirty more quickly. Talk with your service advisor at McLearen Shell 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 McLearen Shell for service.

Cruisin' on Down Main Street

When automakers first came out with cruise control, it was a real luxury item.  The older cruise controls used a mechanical vacuum system but it worked.  Well, some of the time. 

Now days, cruise control is all electronic, thanks to computers.  It's reliable and a real convenience on long trips.  Cruise control is offered on most vehicles and standard on a lot of them.  Because it's electronic, when it breaks, it's usually some electronic component.  Your vehicle's cruise can be the victim of a blown fuse. Or your vehicle's speed sensor, which—not surprisingly—measures your vehicle's speed, can also stop working.  And that will cause your cruise to stop cruising. 

Vehicles with cruise control also have a built-in feature that, when the brakes are applied, turns off the cruise.  With electronic cruise control, that happens thanks to the brake pedal switch, and if a problem develops in that switch, the cruise might not work.

The newest cruise control is called "adaptive." What that means is that it will maintain your vehicle's speed as well as the distance between you and the vehicle ahead of you.  That means if a car ahead of you slows down, your vehicle will slow down to the same speed and even stop if the car ahead stops.  Pretty cool, right? As you can imagine, adaptive cruise control is more sophisticated and has many more components than standard cruise.  The systems vary from manufacturer to manufacturer, but they use on-board radar units and cameras to calculate what your vehicle should do to maintain a safe distance and speed. 

Finally, there are still some of the older style cruise controls out on the roads.  They'll stop working when the vacuum actuator develops a problem, a vacuum hose starts leaking or breaks or the cable between the actuator and the throttle kinks, breaks, seizes up or becomes detached. 

If your cruise control isn't working, your service repair facility will be able to determine what kind your vehicle has and what it will take to fix it.  Good news for the cruise blues.

Water Everywhere (Clogged Drains)

It's bad enough when you mistakenly leave a window open in your vehicle on a rainy day and you find your carpet soaked.  But what in the world is going on when your windows are closed tight, not leaking and you STILL wind up with wet carpet? The answer could be something you might not even know your vehicle has.

And the answer is? Drains. And those drains can get clogged.  Yes, your vehicle has several drains with tubes or hoses attached to them that you really never see.  There are some in and around the hood that channel rainwater down to the ground.  There are some that take condensation from the air conditioner and allow it to flow outside.  And if your vehicle has a retractable sunroof or moon roof, there are small drains at each corner that connect to tubes that go through the vehicle body down to an exit near the ground. 

Considering all the leaves, dirt, dust and other debris your vehicle encounters on a daily basis, it's not surprising that these drains can get blocked.  Then when it rains, that water winds up going to the place of least resistance.  Sometimes, that's inside the cabin where it shows up as wet carpeting.

So, what's the solution?  You may be tempted to see if you can clean out those drains yourself.  But there are many people who have tried blowing condensed air in the drains only to find that they literally blow the tubes off of their connections inside the vehicle's body.  Reattaching those can be a time-consuming, labor-intensive, expensive proposition.

A trained technician has the equipment and knowledge to clear out those drains properly. To prevent clogged drains, regular maintenance is the key, so when your vehicle is in for other periodic maintenance like oil changes and tire rotations, the technician can make sure all drains are clear and flowing like they should.

Got it Covered! (Timing Cover Maintenance)

You may have heard at one time or another about something called a timing belt or timing chain in your engine.  And you may know that if they fail… well, let's just say that there can be some major engine damage.  So obviously, we want our timing belts and chains to be in tip-top shape.

One part that helps keep them running the way they should is the timing cover.  As you can probably guess, it's something that covers the belt or chain.  The timing cover protects both belts and chains from dirt and road debris.  Timing belts also need to be lubricated so their covers allow them to be lubricated as well.  They have a gasket that insures a good seal for the engine.  If that gasket breaks or develops a leak, then engine oil can escape, and loss of lubrication is never good for an engine component.

Other symptoms of a failed timing cover are leaking coolant, a metallic sound coming from the front of your engine or your Check Engine light coming on.  You might also notice a drop in power when you're going uphill.

It's important that your timing cover be in good condition and functioning properly.  Your repair facility will check out that part of your engine to make sure gaskets are in good shape and the cover is doing the job it's meant to do.  Catch that leaking or broken timing cover in time and your engine will thank you for avoiding some serious damage and an expensive repair.

A Door No One Can Step Through (Fuel Door Repair and Maintenance)

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you.

When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time.

A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it. 

You probably want to take care of this sometime soon since your gas cap is wide open and unprotected when the door doesn't shut.  Plus, it's possible that the door could be torn off completely.  Often a stuck open fuel door can be fixed fairly inexpensively and quickly depending on the type of mechanism your vehicle has. Looks like it's an open and shut case.
