The Best Book that's Not a Best-Seller

Sometimes the movie is better than the book, sometimes it's the other way around.  But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance.

And yet, it's amazing that some people will own a vehicle for years and never even crack this book.  They'll only read it when they absolutely have to, for things like finding out how to change the clock. 

Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover.  We know that.  But just think of what you can get out of it.

Consider this.  Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it.  They know more about your vehicle than anyone, period.  They know how long a part is likely to last and what you need to do to take care of it. They know how far a distance or how long a time you can drive before you have to change certain fluids in it.  They know what temperature it can reach before things will start to break.

And they've put your vehicle model through torture, testing it in the absolute worst conditions to see how to make it stand up to more abuse than it will ever receive.  They've then torn it down, examined it and, in many cases, redesigned the parts to make them even better. 

And they've put down—in fairly minute detail—this blueprint that, if you and our experts at Matt Davis Auto follow their suggestions, will make it very likely that your vehicle will serve you well for a long time.  If you don't follow those suggestions, all bets are off.

We didn't even mention that the owner's manual tells you how to operate everything in your car.  How to adjust the heat and air conditioning, how to pair your smartphone with the audio system, how to program your key fob so it won't sound the horn when you lock your vehicle.

Have you lost your manual or did you buy a vehicle that didn't come with one?  Many are available either online or in paper form. If you don't know where to begin with such a long book, try a couple of pages a week, just three minutes.  You’ll discover your vehicle does things you never even knew it could do.  And the movie will never be as good.

Gear Up: Transmission Service at Matt Davis Auto in Garner

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.

How does it know when to change gears? Today's automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing and changes the gears as needed.

Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds,” are being added. Almost all vehicles have at least four speeds. Five or six is common. Some are even increasing to seven or eight – up to ten. Adding gears has a lot of advantages for Garner vehicle owners: it improves fuel economy and increases performance.

But there is a drawback for drivers in Garner: more gears equal more parts and a more complex transmission system. Plus, all those parts need to fit into the same space as older, less complex transmissions. This means that today's transmissions are engineered to much tighter tolerances. In other words, they demand meticulous care from Garner drivers. Transmissions are designed for durability. But that durability can be compromised if they aren't given proper care.

That's why changing transmission fluid is such an important part of preventive maintenance for vehicles in Garner. Transmission fluid lubricates the transmission and keeps it in good working order. But if the fluid runs low, transmission parts will wear out quickly or suffer damage due to increased friction. The transmission can even fail.

Dirty transmission fluid can clog the small passageways in the transmission, blocking lubricant from reaching all of its parts. Again, this can lead to increased wear, damage or failure.

New transmissions aren't cheap. Repairing them isn't cheap either. But changing transmission fluid is fairly inexpensive at Matt Davis Auto in Garner. That's why responsible car care includes maintenance on the transmission system at Matt Davis Auto. It doesn't take a genius to figure out that periodic fluid changes aren't just good auto advice, they actually pay for themselves by preventing transmission repairs.

Below 45 Degrees in Garner: Consider Winter Tires

Remember snow tires? They were basically just regular tires with big, knobby lugs to get them through deep snow. They were loud and rode hard, and Garner drivers couldn't wait to get them off the car. Then along came television advertisements for “all-season” radials. NC drivers ran out and bought some and we thought we were done with snow tires forever.

Tires have come a long way since then. Modern winter tires sold in the Garner area are much better designed for the wide range of conditions that come with NC winter weather. They are made with a rubber compound that helps them stay flexible in cold weather. Regular tires become hard and stiff at Garner temperatures below 45°F (7° C) which reduces their traction. That's a concern in winter, especially with snowy or wet conditions. But it also means that Garner drivers are better off with winter tires in cold weather even when it's dry.

The tread design on winter tires has been improved to move snow, slush and water. The lugs and grooves throw packed snow out of the tread as the tire rotates. This means the tread is open and ready to move more snow when it rolls around again. Summer tires can pack up with snow, which makes them more dangerous than a bald tire.

The all-season tire that is popular among Garner drivers is a compromise between summer and winter performance. This means they give adequate performance for Garner drivers in either season but aren't great in either. Summer tires give great performance in hot weather but lousy performance in winter. Garner drivers need to put more thought into their tire choices these days.

If you want the performance that new winter tires can give you, you should have them properly installed by your friendly and professional service advisor at Matt Davis Auto. It's best to purchase four snow tires and put them on all the wheels of your vehicle. But if you only want two, you need to put them on the rear of your vehicle, even if you drive a front-wheel drive vehicle. Garner drivers always want to put the tires with the best traction on the rear of the vehicle.

For more auto advice about tires for any NC season, ask your friendly and knowledgeable Matt Davis Auto tire professional. They can help you find the right tire for your area and for your driving needs. For the best performance from your tires, whatever the season, don't forget preventive maintenance. Keep your tires up to pressure for the best durability, safety and performance, but don't overinflate them. Remember, good car care provides the safest road for all of us in Garner.

The Right Oil for the Season (Engine Oil Viscosity)

As the temperatures plunge, certain types of engine oil may not flow as easily as they did when it was warmer.  Makes sense, doesn't it? Just like molasses gets thicker as the temperature goes down, engine oil does the same thing. So, maybe you're wondering if you have to change your oil as the seasons change so it's just the right thickness to lubricate your engine parts. 

How well engine oil flows is called its viscosity. There are different types of oil—some that have just one viscosity and others called "multigrade" oils.  Here's the difference.

A single viscosity oil will flow better when it's hot but not as well when it's cold.  A multigrade oil is engineered so that its flow properties at cold temperatures are different than they are at warm temperatures.  In other words, a multigrade oil can start out in colder temperatures acting like a thinner oil and then behave like a thicker oil when it's warm.  That's a pretty cool trick and it's why multigrade engine oil is used in nearly all vehicles.  Your vehicle's manufacturer has the correct viscosity of oil for your particular model included in the owner's manual.

Another choice you have to make when it comes to engine oil is whether you use conventional oil, synthetic oil or a blend of the two.  Synthetic oils have some advantages over conventional, such as resisting breakdown better and withstanding higher temperatures.

Check with your service advisor to see which viscosity and type of oil is recommended for your vehicle.  It's important that in cold weather, the oil flows through your engine at the right thickness so that parts are being properly lubricated.  That will make sure you'll get good fuel economy and performance, no matter what the temperature is.
