Road Trip: Be Ready for Anything with a Trip Inspection at Matt Davis Auto

Road trip, anyone? Nothing spoils a great vacation faster than ending up stranded on the side of the road or spending a week in a rundown motel while our vehicle sits in the shop. Long days on the road can bring out the worst in your vehicle, so before you leave, prepare it for the journey by getting a trip inspection at Matt Davis Auto in Garner. After all, you wouldn't travel without clean socks, why ask your vehicle to travel with a load of dirty oil?

The first step in a trip inspection at Matt Davis Auto is to look at your travel plans. What kinds of roads will you be driving on? Will you be in the NC back country or on the freeway? Will you be crossing mountains? Off-roading? What will the weather be like? How far away from Garner will you be traveling? How much are you hauling? Will you be towing a trailer or lugging a rooftop carrier? Will you encounter dust, mud, snow or sea salt? All of these questions can help determine which services are most needed. And don't hesitate to ask your Matt Davis Auto service advisor. He can give you good auto advice on what trip conditions are hardest on what systems of your vehicle and what kinds of services it realistically needs. Start with the tires and check them for tread wear and proper inflation. Replace or rotate them as needed. If you need to change them out for winter tires, then do so.

Then look at your shocks or struts for wear. Replace them if needed. You'll want that extra comfort on your trip. Be sure to check your alignment as well. Steering a vehicle that is out of alignment is tiring, and dangerous. Don't overlook your brakes. With extra passengers and baggage, your brakes are going to get a workout. You want them in top condition.

In addition, inspect belts and hoses. If any of them are close to wearing out, have them replaced before your long trip does them in.

Change your engine air filter if it needs it, or if it's close to needing it. Your car's air filter processes 12,000 times as much air as the amount of fuel it burns. A clean air filter will protect electronic sensors that affect how your engine runs.

Get an oil change at Matt Davis Auto in Garner if it's coming due. Make it a full-service oil change while you're at it. That way, all of your fluids will get checked and topped off. Change any dirty or old fluids. Garner drivers don't want to overstress their cooling systems or transmissions with dirty fluid during a long trip.

Does your vehicle smell? Check the cabin air filter. The bad smell could also indicate an exhaust leak, which can be fatal on a long trip. So don't ignore bad odors; check them out.

If your air conditioning hasn't been up to snuff, then give it an overhaul. You want your vacation to be relaxed and pleasant, and that means keeping the passenger compartment comfortable.

And be sure to check your wiper blades and your headlamps. You may find yourself driving in unfamiliar territory at night after a long day. You'll want to be able to see as much as possible.

Of course, almost everything listed here is just part of preventive maintenance for smart driving. If you keep up with your vehicle care on a regular basis, a trip inspection will be a breeze at Matt Davis Auto.

Taking care of your vehicle before you leave for a road trip will pay you back in safety, peace of mind, improved comfort and better fuel economy. It will also help your vacation go as planned by keeping you on the road and headed for that next great adventure. Just don't forget to pack your socks.

The Matt Davis Auto Guide to Tire Specs

You know you need new tires, but you're not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the Garner service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.

Tire size can be confusing for many Garner drivers. There's so much on the side of the tire, and it's hard to keep straight.

Even though there's a lot on a tire - if you know what it all means, it's actually more helpful than confusing for Garner tire shoppers. Let's start with the size number.

For example, let's say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters - the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio - the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high performance tires will have a lower number.

The R signifies it's a radial tire. And 16 is the rim or wheel size in inches.

The 92 is the load rating index - it's the load carrying capacity of a tire. The higher the number, the more it can safely carry. Your empty vehicle can be safe with a lower number, but you'll need a higher rating if you routinely haul heavy loads around Garner. The next letter is the speed rating. Not all tires sold in Garner are speed rated. The ratings generally follow the alphabet: the further up the alphabet, the higher the speed rating - with the exception of H - it comes between U and V (don't ask why).

There's a lot of fine print that most Garner area drivers probably need a magnifying glass to read. But there are a couple of other large print items of interest. One is the tread type: highway, mud and snow, all season, severe snow, etc.

And then there are the Uniform Tire Quality Grading System markings. The first is a tread wear index. 100 is the base line - a lower number is poorer and a higher number is better. All things being equal, a tire rated 200 would wear twice as long, on a government test track, than one rated at 100. These wear grades are only valid within the manufacturers product line - you can't compare with others. And it's important to note that a lower rating might be just what you want - a high performance, sticky tire has a softer rubber compound and won't wear as long, but boy, will it take those corners on twisting NC roads.

The next is a traction grade. This measures the tire's ability to stop on wet pavement in government tests. A - the best, B - intermediate, C - acceptable.

Temperature grade measures a tire's resistance to heat buildup in government tests. A, B and C - from best to acceptable.

It's safe for Garner drivers to go with the vehicle manufacturers original equipment recommendations that came on your car. But if you want to make adjustments, you'll now be better equipped to communicate with your friendly and knowledgeable Matt Davis Auto tire professional.

No Yolk! Rotten Egg Smell (Sulfur Smell Causes)

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S.  Sulfur.

Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up. 

If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe.

There's another possibility, but it's usually only in stick shift vehicles.  That's leaking, old transmission fluid.

Catalytic converter repairs are best left to a professional. Technicians at your vehicle service facility have equipment and training that can help them pinpoint the cause of this funky fragrance.  Once the cause is found, repairs made and/or parts replaced, the smell should go away fairly rapidly.

How Much is Enough for Garner Auto Owners? Tire Tread Depth

Most Garner drivers know that tires wear out and that the wear has to do with tread depth. Most of us have heard that “bald” tires are dangerous, but most of us picture a tire with no tread at all when we think of a bald tire. And when we take our vehicles in for preventive maintenance, the technician tells us they're need to be replaced long before all the tread is worn off. Just how much tire tread wear is too much? And how can you tell? Tires are and their condition is important to the safe handling of a vehicle, so it's for Garner vehicle owners to know the answers to these questions.

First of all, it's important to understand that there may be a legal limit to tread wear. If your tires are worn past this limit, you have to replace them to be in compliance with NC auto safety laws. That's why measuring your tread wear is part of a vehicle safety inspection.

In some jurisdictions, tread must be at least 1.6 millimeters or 2/32 of an inch thick. This standard has been in effect since 1968. But this standard has recently been called into question, and some NC professionals are arguing that it be changed.

The safety issue that has brought this standard under scrutiny is the ability of a vehicle to stop on a wet surface. When a vehicle has trouble stopping, most Garner drivers immediately look at the brakes as the source of the problem. But tires are crucial to safe stopping distances because they provide the traction required in a stop.

A tire's contact with the road surface creates traction, which allows for effective braking. On a wet surface, a tire only has traction if it can get to the road's surface. So tire tread is designed to channel water out from under the tire to allow it to stay in contact with the road. If the tire can't shift the water, then it starts to “float.” This condition is called hydroplaning. It is very dangerous for Garner drivers since the vehicle won't stop no matter how hard the driver presses the brakes. Steering control is also lost.

A recent study tested the stopping ability of a passenger car and a full-sized pick-up on a road surface covered with only a dime's depth of water (less than a millimeter). The vehicles were traveling at 70 mph (112 kph) when they stopped on the wet surface. At 2/32 (1.6 mm) tread depth, the stopping distance was double that of a new tire. The passenger car was still traveling at 55 mph (89 kph) when it reached the stopping distance it experienced with new tires.

Let's suppose that you're on a busy Garner road in a light drizzle and a vehicle stops suddenly in front of you. You just bought new tires and you brake hard, missing the vehicle with only inches to spare. If you hadn't bought those new tires, you would have crashed into that vehicle at 55 mph (89 kph). That is a major difference.

What if your tires had a tread depth of 4/32 (3.2 mm)? You would have crashed into that vehicle at 45 mph (72 kph). Still not a good situation. But it's better.

Now what if you were driving that pick-up truck? You wouldn't have missed that vehicle in the first place, and you would have crashed at higher rates of speed in both of the other scenarios. The heavier your vehicle, the longer its stopping distance. It's a matter of physics.

The results of this test has led Consumer Reports and others to ask that the standard for tread wear be changed from 2/32 (1.6 mm) to 4/32 (3.2 mm). The increased standard will improve safety on the road and save lives here in NC and nationally.

Of course, until the standard changes, you'll have to decide whether you'll be willing to replace your tires a little sooner.

You can use an American quarter to tell if your tread wear is down to 4/32 (3.2 mm). Place the quarter into the tread with George's head toward the tire and his neck toward you. If the tread doesn't cover George's hairline, you're under 4/32 (3.2 mm). With a Canadian quarter, the tread should cover the digits of the year.

You can measure the 2/32 inch (1.6 mm) tread wear with a penny. If the tread touches the top of Abe's head, it's at 2/32 (1.6 mm). Tires are super important when it comes to vehicle care. But their condition has a major impact on safety. We need to decide whether to sacrifice safety for economy. Keeping our tread wear above 4/32 in (3.2 mm) is good auto advice.

Are Modern Vehicles Maintenance Free?

In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern vehicles are so reliable, they are virtually maintenance free."

Any good myth has some elements of truth. No offense to Garner Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.

Here are some examples for our friends in Garner.

• Some vehicles in Garner no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally no way to grease those joints.

-Chalk one up for the myth.

On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts are up in the valve train that didn't even exist not that many years ago. These parts are very vulnerable to oil sludge.

• So, skipping an oil change here and there could lead to very expensive damage.

-A point to maintenance.

• Electronic ignition has eliminated replacing points.

-Myth gets a point.

• Fuel injectors on direct injection engines are very expensive to replace so one must be sure to get a fuel system cleaning on schedule.

-Point for maintenance.

I think you get the picture. As automotive technology advances, it eliminates or reduces some maintenance requirements. And maintenance becomes more critical for some items. Most others remain very similar to what they've always been.

So the maintenance mindset is still important for car owners in Garner if we want our vehicles to last a long time. The checklist may change over time, but there'll always be a check list. Your friendly and professional service advisor at {[ Shop }} can answer any questions you have about your vehicles maintenance schedule.
