McLearen Shell: Why Replace Your Engine Air Filter?

Just as our bodies need clean air to function properly, your vehicle engine needs clean air to operate efficiently. Let's go egghead for a minute. For every gallon of gas we burn driving on Herndon streets, 20 pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce 20 pounds of carbon dioxide?

The answer is that the carbon comes from the gasoline, but the oxygen comes from the air. You see, it takes about 12,000 gallons of air to burn a gallon of gas in your engine. Clearly, your vehicle needs a lot of air to keep going in Herndon. A lot of clean air is best.

You've seen the pictures of people in Japan wearing face masks. They want some kind of filter to keep unwanted pollution and germs out of their lungs. Well, your vehicle also works better when its internals are clean. When your vehicle air filter is dirty, it simply can't trap any more dirt, so the pollutants just pass through into your air intake system. From there it can clog your fuel injectors and even get into the motor itself. Not surprisingly, burning dust and pollen in your vehicle engine does you no good.

Replacing a dirty air filter at McLearen Shell in Herndon can improve your fuel economy by up to 10 percent. At today's Herndon fuel prices, you should be able to pay for a new air filter before your next oil change.

The verdict: When your vehicle engine air filter needs to be replaced; it needs to be replaced. How often depends entirely on the level of air pollution where you drive in VA. A simple visual inspection at McLearen Shell in Herndon will tell you when you need a new engine air filter.

Many people in VA are keeping their vehicles longer. The economy has influenced that, but the fact that modern vehicles are more durable and reliable means that owning a high mileage vehicle doesn't have to be a painful experience.

Local car owners in Herndon with over 100,000 miles on their vehicles often ask which service intervals they should follow. Let's start with the special needs of the older vehicle...

The reality is that time and mileage will take its toll. The engine and transmission will have more sludge. The fuel, steering and brake systems will have gum and varnish built up. There'll be more dirt and contaminants in the fuel tank. Corrosion and deposits in the cooling system. And seals and gaskets will start to dry out.

All of this, plus normal wear and tear, means that the engine might not be as strong as new, so it just has to work harder to get the job done.

So we need to compensate. Consider high-mileage formulations for oil changes, transmission service, etc. These special formulations contain additives that condition the seals and gaskets to prevent leaks. They also have more detergents to clean sludge and other deposits. They cost a bit more, but they're worth it.

In general, if an auto service was recommended every 15,000 miles when the car was new, you should continue to get the service done every 15,000 miles.

Talk with your Herndon service advisor at McLearen Shell about the condition of your engine. See if he thinks you should adjust your auto service intervals for oil changes or other auto maintenance to account for the older engine working harder.

Expect the oil filter to get dirty faster. Same goes for the fuel filter. And some leaks are to be expected so you need to keep a closer eye on fluid levels.

If anything, following recommended service intervals for your vehicle is more important in a higher mileage vehicle. Skipping oil changes or other services can lead to problems much more quickly than with a newer vehicle.

So, have your Herndon auto service advisor at McLearen Shell help you with an assessment of your older car or truck. If you haven't gotten around to a fuel system cleaning, or replacing power steering or brake fluid, a differential service or transmission service – it's time to start taking care of those things. It'll help keep you on the road for many more happy miles.

A Stitch in Time at McLearen Shell

You probably have heard that expression, "A stitch in time saves nine." In other words, if you fix an issue at its early stages, it will prevent a much more difficult problem later. That's certainly the case with your vehicle, and here's a true story to demonstrate it.

A driver noticed his vehicle was due for an oil change, so he took it in to his service facility early in the morning so he could wait while the work was performed. The technician routinely checks the battery on vehicles just before extreme weather is approaching (cold or hot), so with winter coming up, he hooked up the load tester (it measures voltage while a load is put on the battery). It showed the battery wasn't holding a charge well.

The technician checked the manufacturing date on the battery, too (most batteries have a date stamped in code somewhere on them). The date showed it was five years old. While batteries can last more than five years, many technicians say you should expect to get anywhere from three to six years out of them, depending on what they go through.

So, this battery was getting a little long in the tooth, and it wasn't holding a charge particularly well. But how much current was it being sent by the vehicle's alternator? If it wasn't getting enough, that might be a factor. A test of the charging system showed the alternator was putting out the correct amount of power. The technician recommended replacing the battery, and the driver agreed.

That was the stitch in time. Had the technician not checked the battery, that driver likely would have been stranded the next time he tried to start his vehicle on a very cold day. What originally was supposed to be just an oil change led to a technician's sharp diagnosis and a little preventative maintenance for one fortunate driver. Sometimes timing is everything.

Emergency! (Vehicle Emergency items)

"I never expected it could happen to me." Countless drivers have said that after they've had an emergency turn their lives upside down. So before that happens to you, let's thinking about planning ahead for an emergency with a few things you should keep in your vehicle.

• Road flares. If you've ever driven by a disabled vehicle sitting at the side of the highway at night, you know how terribly hard it is to see, especially in bad weather like rain.  If you are the one in that broken down vehicle, you run the risk of being hit by a vehicle whose driver literally may not be able to see you.  The best emergency signal includes one or more road flares.  There's a reason police officers and firefighters carry them in their vehicles.  When you see a series of burning red flares at the side of the road, you know something serious is going on.  These are far more visible at a much longer distance than nearly any other portable signal device.

• Fire extinguisher.  Thousands of vehicles catch fire every year.   Most fires start small but can get out of control. It's vital to have a fire extinguisher in your vehicle, and there are several small ones designed especially for the job.  Since many different types of vehicle fires can start, make sure the extinguisher you choose will handle every fire from gasoline to electrical. Some have handy mounting brackets. And keep it up to date!

• Flashlight.  Sure, your cell phone likely has a light in it.  But you will need that phone for communication if there's an emergency. Plus, the light’s just not that bright.  So carry an LED flashlight designed for automotive use.  LEDs produce a lot of light with little power; plus, many of those designed for vehicles include a lantern which will light up a wider area. It’s vital if you have to read your vehicle's jack instructions or tend to an injured person.

• Drinking water and snacks.  If your vehicle breaks down during bad weather and you may be forced to stay with it for a long time, you'll need food and water to survive until help can arrive.  These are simply the necessities of life, so have a small supply on hand, just in case.

Other things like basic tools, a first aid kit, a space blanket and jumper cables are also good ideas.  Many service repair facilities offer these items for sale, and you can ask your service advisor for suggestions.  While it's fresh in your mind, plan a shopping trip and put together your own emergency kit now.  Sure, you can put it off, but you may find yourself stuck in a difficult situation, saying to yourself, "Only if…"
