Fuel Saving Tip: Car Weight and Your VA Driving

Weight is the enemy of fuel economy. Everyone from Herndon knows this makes sense.

Some of us in the Herndon area carry a bunch of unnecessary weight, and I'm not talkin' what you see in the mirror.

Guys: sports equipment and tools. Ladies: well, just take a look around the passenger compartment and trunk. I think my car has about 45 pounds of french fries on the floor.

All that extra weight wastes gas as you drive between here and there, and everywhere else.

Lose the junk and save some money.

...And you really only need one of those spare tires.

Smart Herndon Drivers Protect Against Overheating

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for Herndon drivers to prevent.

The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine and then flows to the radiator. Air passing through cooling fans on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again.

The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage.

Different engines require different types of coolant/antifreeze. The owner's manual will list what kind a vehicle requires. Using the wrong type or mixing different types of coolant/antifreeze may void the warranty on the cooling system and may damage it as well.

Insufficient coolant can lead to engine failure. Coolant levels need to be checked regularly and topped off as necessary. If coolant levels drop quickly or consistently, the cooling system should be inspected for leaks. Coolant/antifreeze contains additives that protect the radiator and other coolant components from rust, scale and corrosion. Over time, these additives are depleted, so it is necessary for Herndon drivers to replace coolant at specified intervals. Changing coolant should be part of routine preventive maintenance for any vehicle.

This service is often ignored, though, since old coolant still cools the engine. Vehicle owners don't realize there is a problem until the system fails. They are left with major repairs and possibly a damaged engine, which could have been prevented with a cooling system service at McLearen Shell in Herndon.

If your vehicle sends a warning message to check its coolant or if the temperature gauge is reading in the red or hot zone, then the cooling system needs serviced. This service is critical and should not be put off since the potential for damage is high.

In an emergency situation, water or antifreeze can be added to your vehicle so that it can be driven to a service center for proper car care. For this reason, your owner's manual contains instructions for how to top off insufficient coolant – allow 45 minutes for the engine to cool before attempting to add coolant or water. However, the fluid should be added to the coolant overflow bottle, not to the radiator itself. Removing the radiator pressure cap can result in severe burns.

Topping off in an emergency, however, does not fix the problem. The vehicle should immediately be taken to McLearen Shell in Herndon where they can inspect the cooling system, repair any leaks and clean it if necessary. They can identify what caused the emergency situation in first place and ensure it doesn't happen again.

Regular maintenance of a vehicle's cooling system is just good auto advice for Herndon drivers. Cooling system service is relatively inexpensive and doesn't take long at McLearen Shell. Lack of it, however, can put a vehicle in the scrap heap.

McLearen Shell: Good Service and Good Fuel Economy

Most Herndon auto owners want to save on gas and seek our advice on improving economy. At McLearen Shell, we are frequently asked, however, if it is really worth the extra effort. Just how much money can Herndon drivers actually save?

In today's McLearen Shell article, we're focusing on the things you can do to improve your vehicle’s economy driving around VA. We'll tell you the potential savings per gallon of gas at $3.50, and we'll show a chart that also shows the savings at $3.00 and $4.00.

DOLLARS PER GALLON $3.00 / $3.50 / $4.00

TUNE UP 4%.12.14.16

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best mileage. A clean air filter means you get plenty of air. The fact that the air's clean protects your engine. That can save you up to 10 percent or 35 cents a gallon.

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

AIR FILTER 10%.30.35.40

Fixing a faulty oxygen sensor can improve economy by up to 40 percent. That's a whopping $1.40 in savings per gallon. Bring your car to McLearen Shell in Herndon and we'll check your oxygen sensor.

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

FAULTY O2 SENSOR 40%1.201.401.60

Chances are that if your oxygen sensor is kaput your Check Engine light will come on. Now, there are any number of things that could cause your Check Engine light to come on besides oxygen sensor problems. But if it's on, get it checked out as soon as you can at McLearen Shell.

Here's an easy one for Herndon auto owners. Inflate your tires to the recommended pressure. That could save you three percent or 11 cents a gallon. Even a little drop in pressure will bring down your economy, so check your tires every week.

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

TIRE INFLATION 3%.09.11.12

Your vehicle has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced economy, or up to seven cents a gallon.

Another thing Herndon vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping 100 pounds of extra weight adds up to a 2% savings at the pump.

So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in VA.

Ask McLearen Shell: What Happens When a Serpentine Belt Breaks?

The serpentine belt is aptly named since it snakes around under your hood. It may lack its namesake's fangs, but it sure packs a wallop when it breaks.

The serpentine belt powers a lot of engine systems. It runs the alternator, which charges the battery; the water pump (on some vehicles), which cools the engine; the air conditioning, which cools the driver and passengers; and the power steering pump, which allows for easier steering. When the belt breaks, all of these systems shut down.

Okay, so maybe you can live without air conditioning and power steering for a while, but your battery can't live very long without an alternator, and when the cooling system goes down, your vehicle engine will overheat. That's why Herndon drivers should never wait to get a serpentine belt replaced.

Serpentine belts are fairly inexpensive at McLearen Shell in Herndon. And they look downright cheap when you compare them to the cost of an overheated vehicle engine, a tow truck, time lost on the road, inconvenience, and the potential safety consequences of being stranded.

Good car care means never putting off preventive maintenance. Do yourself a favor. Ask your friendly and knowledgeable McLearen Shell  technician to glance under your hood and give that serpentine belt a quick look-over.
