The Steve & Stacy's Servicenter 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 Steve & Stacy's Servicenter 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.

Slipping into Fall (Driving with ABS Brakes)

As the weather changes over from hot to colder, drivers will have to deal with more slippery streets.  And it's important to know how to drive with the brakes you have on your vehicle. 

In the 1970s, anti-lock braking systems (ABS) started to be installed on vehicles and they've been a game changer for drivers.  Most modern vehicles have ABS and it's important to know how to drive with them.

In older vehicles without ABS, the driver applies the brakes by pushing down the pedal.  That, in turn, sends braking pressure to all four wheels at once.  But all four tires don't have the same traction because the road surface they're each on isn't exactly the same.

ABS allows sensors to determine when particular wheels are slowing down more quickly.  The ABS then reduces braking pressure to the wheels that are about to lock up.  That way the wheel turns and the tires keep some grip. (You have to have grip to stop.) It's kind of what drivers try to achieve when they pump the older-style brakes without ABS.

Another engineered feature of ABS is that it makes sure your front wheels will continue to rotate and maintain some traction.  That's important because the front wheels are used to steer, and being able to steer gives a driver more control in a quickly-changing situation.  So ABS is all about stopping as fast as the road surface will allow but at the same time enabling the driver to maintain control. 

ABS is designed for the driver to put steady pressure on the brake pedal and let the vehicle’s computerized system handle the braking.  Pumping the pedal in a vehicle with ABS can defeat what the system is trying to do to help you maintain control.

Because stopping techniques in a vehicle with ABS are different than those without, it’s important to know which brakes you have so you can operate them accordingly. 

If you have any doubt, consult your service advisor.  ABS involves sophisticated technology and must be maintained in order for it to work properly.  Your service advisor can recommend a maintenance schedule for you to follow so your ABS is always on the ready to help you stop when you need to.

Stop It! You Need Good Brakes

Good brakes are obviously very important. If you've ever had your brakes go out while you're driving around the Charleston area, you'll know how terrifying it can be. Today we'll focus on how to tell when you have a brake problem and how to make good repair choices.

Often, the first indication that something's wrong with the brakes is an unusual sound. It could be a squeal, chatter or grinding sound.

Some brake pads have a little piece of metal embedded in them that will make a squeal or chirping sound when the brake pads have been worn down to the point that they need to be replaced. It's an early warning indicator.

When you hear that sound, schedule an appointment at Steve & Stacy's Servicenter soon.

Now a chattering sound is more urgent. That usually indicates that something is loose. It could be a brake pad or even the brake calipers. If one of those parts falls off, you could have some serious trouble stopping the vehicle. It would be a good idea to park it until you can get into the shop.

A grinding noise usually means that the brake pad is completely worn away and the metal parts of the brake are rubbing directly on the metal brake rotor. That means the rotor is being damaged and will need some work. More on that later.

Another warning sign is that your brake pedal may feel soft and spongy – or it may even feel very hard to push in. Both could mean trouble. And of course, you may get a dashboard brake warning light.

Now when it comes time to replace your brake pads, you have a choice to make. You can get the same pads that came standard on your vehicle. You can expect the same performance and durability as with the pads that came on the car from the factory.

Now you can also get a budget brake pad. Sometimes Charleston drivers insist on lower cost pads. That's OK if the budget demands it, but you need to be aware of the tradeoffs. Lower grade pads are usually noisier, so you'll have to live with more noise when you apply the brakes. They also tend to generate a lot more brake dust, you know, that black dust that accumulates on your wheels. And they probably won't last as long either. In our opinion, that's a lot of compromise for just a few dollars in savings.

You can also choose to buy premium brakes pads at Steve & Stacy's Servicenter. These perform at higher specifications than the factory pads. You can expect quieter operation, less brake dust and better stopping power.

Now, getting back to the rotors. The rotors are the discs that the brake pads clamp down on to stop the vehicle. If you've been driving with completely worn brake pads, you've scratched grooves into the rotors. If the grooves aren't too deep, the rotor can be resurfaced. A thin layer of metal is cut off the surface of the rotor to make it smooth again.

Now, if the grooves are too deep or if the rotor has already be resurfaced before, there may not be enough material to resurface and still have a rotor that's thick enough to safely stop the vehicle. In that case, the rotor will have to be replaced.

Something that's often overlooked is the brake fluid. Your manufacturer has a recommended schedule for evacuating the old brake fluid, cleaning the system and refilling it with fresh brake fluid. This is really important to brake performance.

So here's the bottom line: if you suspect, inspect. If you notice any of these warning signs, have your brakes inspected at Steve & Stacy's Servicenter in Charleston. Your service advisor can help you make the repair decision that's right for you.

PCV Valve: What Is It?

Most Charleston drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.

PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.

When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. Charleston vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can blow gaskets and damage seals, leading to oil leaks.

The waste gases that leave the engine are comprised of about 70% unburned fuel. They used to be vented off the crankcase into the atmosphere. But starting in 1964, laws mandated that these gases be recaptured. Manufacturers began installing PCV systems, which recycled the gases into the air intake system where they could be mixed with fuel and sent to the engine to be burned.

The PCV valve is a one-way valve attached to the crankcase. Waste gases exit the crankcase through the valve but cannot enter.

Over time, the waste gases leave deposits on the PCV valve that can gum it up. So it needs to be replaced occasionally. This is an inexpensive part of preventive maintenance that is often overlooked, but which can have very expensive consequences. It's good auto advice to keep this little valve clean and working well.

In order to maintain efficient circulation, the PCV system also has a breather tube that allows clean air to enter the crankcase. This air is usually filtered through the engine air filter. But some vehicles have a separate air filter for the breather tube called the breather element. If this is the case with your vehicle, proper maintenance of the PCV will include replacing this element. To find out whether your vehicle has this type of PCV system, check your owner's manual or ask your service advisor at Steve & Stacy's Servicenter.

The PCV system reduces harmful vehicle emissions. The maintenance it requires is simple and inexpensive at Steve & Stacy's Servicenter. A fouled or damaged PCV system can lead to serious engine damage for Charleston drivers.

Let's all learn to practice good car care. It's good for our wallets, and it's good for our WV environment.
