The Hill's Auto Repair, Inc. Guide to Servicing Your Differential

Differential? What's that? And what's it for? I've been told by my service advisor that I need to get it serviced, but is that on the level?

Do these questions sound familiar? They're not uncommon for Bushwood drivers. A lot of us in Bushwood don't know what a differential is or what it's for. Every vehicle has a differential, and, yes, it does need to be serviced. In fact, it's more important to the operation of your vehicle than the air conditioner or windshield wipers.

A differential allows your vehicle tires to move at different speeds. This happens more than you think. The best example is when a vehicle is turning. The inside wheel travels a much shorter distance than the outside wheel during a turn. This means the outside wheel has to move faster than the inside wheel. Without a differential, your tires would hop and skip while turning. They would also lose traction in sand or snow.

The location of your differential depends on what kind of vehicle you drive. On a rear-wheel drive vehicle, the differential is located in the back. For a front-wheel drive vehicle, it is located on the front, but it is usually called a transaxle. Four-wheel drive vehicles have three differentials: one on the front, one in the back and one in the middle. This center differential compensates for differences in speed between the front and rear wheels.

Your differential contains strong gears that need to be protected from dirt, debris, water and other contaminants. A differential is sometimes referred to as a “gear box.” The work of these gears is to transfer power from the vehicle drive train to the wheels.

Your differential needs fluid to lubricate and cool the gears. This fluid, even though enclosed in the “gear box,” can get dirty because the gears grind down over time, releasing tiny bits of themselves into the fluid. Also, the additives in the differential fluid break down and need to be replaced. That's why preventive maintenance for your vehicle needs to include servicing the differential.

Your owner's manual can give you recommendations on how often to service your differential. But you should also consult with your friendly and knowledgeable Hill's Auto Repair, Inc. professional. Hill's Auto Repair, Inc. can give you some good auto advice on whether your vehicle needs to be serviced more frequently. For example, if you drive in hot or cold Maryland weather conditions, your differential will need to have its fluid changed more often.

Severe conditions will also affect your vehicle care routine and your differential. Check your owner's manual for a definition of “severe service” conditions that affect your vehicle. Examples may include driving with frequent stops and starts, a lot of short trips around Bushwood, hot or cold Maryland weather conditions and towing.

Off-roading is particularly hard on a vehicle's differential. If you are an off-roader, especially if you cross Maryland streams or waterways, it is important that you service your differential more frequently than the recommendations suggest.

Properly servicing your differential will extend its life and keep you out of Bushwood auto repair shops. A smooth ride is the result of proper preparation and smart choices.

Automotive Tips from Hill's Auto Repair, Inc.: Making Your A/C System Last Longer

Bushwood drivers know that if their air conditioning system isn’t making cool air like it used to, there is a problem. It may be as simple as adding more of the right kind of refrigerant.

Your A/C requires special compressor oil, which circulates through the system along with the refrigerant, to lubricate and protect expensive components and keep seals and gaskets from drying out. If refrigerant has leaked out – so has the compressor oil. This oil needs to be replenished whenever refrigerant is added.

An air conditioning inspection at Hill's Auto Repair, Inc. will uncover any potential problems and identify any necessary repairs needed to get Bushwood drivers on the road to cool air once again.

Give us a call.

Good Service at Hill's Auto Repair, Inc. Equals Good Fuel Economy in Bushwood

Whether we're trying to save money, save gas or save the environment, most of us Bushwood drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in Maryland, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?

The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.

Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The fuel doesn't burn efficiently. Replacing that faulty sensor can save you 40% at the pump. That's certainly a reason to improve your car care and have the automotive professionals at Hill's Auto Repair, Inc. inspect things once in a while.

A faulty oxygen sensor will activate the check engine light. So will a lot of other problems that are big fuel wasters. Finding out why your light is on and fixing the problem will also improve your fuel economy. Bring your car into Hill's Auto Repair, Inc. in Bushwood and we will take care of it for you.

What about tires? Bushwood drivers have all heard that keeping them inflated will improve our gas mileage. True? Yep. It's a 3% savings for that one. And even small drops in tire pressure can start to add up, so a weekly tire check is in order.

Using the correct weight in motor oil is another way you can save at Bushwood area gas pumps. It adds up to a 2% savings.

What about that courteous driving? That doesn't cost us anything and doesn't require our Bushwood service center to implement anything. Is it worth the bother?

Again, the answer is yes. Sudden acceleration, such as charging away from stoplights, sudden stops and quick lane changes all add up in lowered fuel economy. Taking it easy when you drive on Maryland roads amounts to a 5% savings around town and a whopping 33% savings on the freeway. Is it worth your time to slow down? How much do you get paid?

Speeding is another way we ding ourselves at the gas pump. We've all heard that it's okay to drive five miles over the speed limit, but that actually hurts our wallets. Eventually it could add up to more than a speeding ticket. An extra five miles over the speed limit ends up costing us 7% per gallon. Fifteen miles over? 23% Now there's a reason to slow down.

Another thing Bushwood 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 one hundred 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 Maryland.

Automotive Tips from Hill's Auto Repair, Inc.: Making a Battery Last Longer

One thing all Bushwood drivers can do to extend the life of their battery is to keep it clean. A greasy, dirty battery holds in damaging heat. Same goes for removing corrosion from the terminals. Hill's Auto Repair, Inc. can help maintain your battery.

Allowing your battery to be deeply depleted – like from using your headlights when the engine is off – is very harmful to your battery. Most automotive batteries can only take that about 10 times before they are ruined.

Also, making sure you have a full charge every month or so extends battery life. Either an extended drive at freeway speeds around the Bushwood are or using a battery charger will preserve your battery’s ability to hold a full charge.

Hey Bushwood Drivers; What Is the Most Distracting Food?

So what is the most distracting food to have in the car while driving around Bushwood?

Is it:

1. A Hamburger;
2. Coffee;
3. A Soft Drink, or
4. Gummy Bears?

Well, you may be surprised to learn that all but the gummy bears are in the top ten most distracting foods when you are driving. But if you chose 'coffee,' then give yourself an extra two points.  Coffee is the number one food distraction for drivers in Bushwood and around the country.

Food distractions cause 25 percent of all car accidents; over a million and a half each year!

You'll notice that all of the top ten distracting food items are messy. Messy foods are the types of food you might spill (very distracting!), then try to clean up (a safe-driving impossibility!). If you gotta eat on the run, take five-then drive. You'll thank yourself later for two reasons: one, that you can actually relax for just a moment in our fast-paced world, and two, you won't have to worry about getting that cinnamon roll frosting out of your dashboard after that near miss.

Keep drinks in spill-proof containers, too, so you can keep your eyes on the Bushwood road without worrying about where that spill is headed.

So, taking a food break… or filling out accident reports. We don't have to ask you which you prefer; it's a no brainer.
