Oil's Well That Ends Well (Oil Change Grades and Weight)

Changing your oil regularly is one of the most important things you can do to keep your vehicle running well.  And knowing the right type of oil to use is also very important. 

Engine oil is classified by weight, but it doesn't refer to how much the oil would weigh if you put it on a scale.  It refers to viscosity, or how easily the oil flows through the engine.  Most engines operate normally at around 210°F/99°C.  The viscosity, or weight, is assigned a number by how well it flows at that temperature.  The lower the number, the more freely it flows. 

Most vehicle engines use what's called a multigrade oil which behaves differently in different temperatures. Multigrade oils have a "W" in their viscosity number that you may have seen on a bottle of oil, something like 5W30.  The W stands for winter and shows how freely it flows in colder temperatures.

That means a 5W30 oil will behave like a 5 weight oil in lower temperatures (less viscous or thinner) and a 30 weight oil in warmer temperatures (more viscous or thicker).  That's important on a cold day because the oil needs to behave like a thinner oil when you start your engine since it need to lubricate engine components immediately to protect the metal components. Then as the engine warms up, it behaves like a thicker oil to prevent friction among those parts.  Pretty neat trick, right?

The type of oil you use can differ depending on what type of climate you operate your vehicle in and how your vehicle is used (carrying big loads, towing, etc.). Your owner's manual contains several different recommendations based on these factors.  Your service advisor can recommend the right oil for your needs.  Like Shakespeare said, "Oil's well that ends well."

The New Blade in Town

If your windshield wipers are streaking and chattering when you turn them on in the rain or snow, it's time for a little "blade renewal." And when it comes to new wiper blades, there are some new designs that are worth a look.

One of the latest is called the beam blade.  It's different than conventional blades you might be used to.  Instead of a metal frame and a rubber blade that slides in the frame on a track, the beam blades have an enclosed spring-steel band that allows the rubber wiper to conform to the windshield glass shape much more tightly. 

There are some key advantages to beam blades, which is why many vehicle manufacturers are making them standard on their latest models.  For one thing, they work well in all weather conditions, including the heat of summer and the icy, snowy cold of winter.  Since there is no separate frame, snow and ice can't form in gaps like conventional wipers and prevent the blade from clearing your windshield. 

Many beam blades also have a mini "wing" on them. It uses the air moving over your windshield to create a little extra downward pressure that presses the blade even more tightly against the glass.  The faster you go, the more firmly the blade can sweep off moisture. That means a clearer view. 

Beam blades are an upgrade that can add to your vehicle's overall safety with that increased visibility.  The best thing is to discuss wiper blades with your service advisor to see if it's a good choice for you and your vehicle, keeping in mind the type of driving you do and the climate you live in.  Remember that when it comes to wipers, it's important that you are using blades that are designed to fit your vehicle and that they are installed correctly.

A Clean Start (Battery Cleaning)

You may be fanatical about keeping the outside of your vehicle clean.  But what about what's under the hood? Have you ever thought about how dirt and grime may be affecting your engine's components?

One of the most important parts under your hood to keep clean is your vehicle's battery.  With a daily barrage of dirt and moisture, outside parts of your battery can corrode, namely the cables and terminals.

Gases vented by batteries can also promote corrosion.  That can create connection problems and affect your vehicle's electrical system.  If corrosion is not cleaned off, it may damage wires and terminals so badly that they will stop properly conducting electricity.  At that point, they may need replacing.

When you bring your vehicle to us for a battery inspection and cleaning, we will remove any corrosion and put corrosion-resistant protection on each post. A technician will also visually inspect your battery.  Plus, we can test how much life is in your battery as part of a more comprehensive battery service. 

Batteries don't last forever and should be regularly cleaned, inspected, and tested.  Usually, they'll need to be replaced anywhere from three to five years after they were first installed, but their lifespan depends on how, where, and how much you drive.  Your battery is a very important component of your vehicle.  Keep yours in tip-top shape, and it's less likely to let you down when you need it most.

The Dennis Road Automotive Basic Guide To Synthetic Oil

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.

Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.

Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.

Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.

Remember that marbles and pencils thing we were talking about? Well, that makes synthetic oil slipperier than conventional oil which means less friction in your engine. Your vehicle engine runs cooler, wears less and lasts longer. You also get a boost in power and maybe even an improvement in fuel economy.

Synthetic oil also lasts longer so you change it less often – which is great for the environment. With longer oil change intervals, you need an oil filter specifically built for the longer service life of synthetic oil. Talk with your friendly and knowledgeable Dennis Road Automotive service adviser about synthetic oil and synthetic blends – they might be just what you need to improve engine performance and extend the life of your vehicle.

The Neglected Windshield (Windshield Care)

You look at it every day, yet you don't really see it.  We're talking about your vehicle's windshield, and if you're not seeing it at all, that's probably a good sign.  The fact is that unless our windshields get fogged up, hazy or cracked, we don't pay all that much attention to them.  Considering how vital front visibility is in a vehicle, paying a little more attention to your windshield will pay off in the long run.

Keep it clean!  In ancient times when gas stations had attendants who filled your tank for you, they used to clean the outside of your windshield while the fuel was being dispensed. In these days of self-serve gas, we don't have that luxury any more.  But it's a good idea to clean your windshield regularly, even when it's not filthy. If you let dirt build up on the outside, it acts like fine sandpaper when you turn on your wipers when the glass is dry. Really, try to avoid turning on your wipers unless your windshield is wet.  If you must use your wipers to clear off something like bird droppings, use your washers liberally to help avoid scratches.

It's also important to wash the inside of the windshield, too. Even if you're not a smoker, you might notice the inside glass sometimes get a greasy film on it.  That's the plastic inside your vehicle off-gassing petroleum products that they're made of.  A hazy windshield when you are driving directly into low sun can blind you.  Use soaps that are made for automotive glass since they won't streak or harm vehicle interiors.  Your service advisor can recommend some.

Keep an eye on your windshield wiper blades.  Let them go too long without replacing them and you might wind up with the metal wiper frame actually touching the glass, a recipe for major scratches when you turn your wipers on.

Finally, do a quick inspection every once in a while for chips in your windshield glass.  Catch them quickly and they can be repaired while they're still small.  Often they will spread into a major crack, and at that point you'll have to have the whole thing replaced. 

So there you have it. Give your windshield a little love and it will reward you back with a beautifully clear view of the road up ahead.
