If you own a newer vehicle, your vehicle’s manufacturer may require that it use synthetic oil instead of conventional oil.  Synthetic oils are more stable, don’t break down as easily, and provide better engine protection than conventional oil. All those things can prolong the life of your engine and help it run better. Imagine the damage that could happen to your engine as it operates at high speeds and very hot temperatures.  Oil reduces the friction between the metal parts.  That’s why it’s important that it maintains its lubricating properties for a long time, which synthetic oil does better than conventional oil.   Clean oil is better than dirty oil because it has fewer impurities.  Synthetic oil is purer because of how it’s formulated and manufactured.  Plus, as the outside temperatures change, the ability of oil to operate in those conditions is important.  
For example, the colder it gets, it’s important f

If you have a front-wheel-drive vehicle, it has components called CV joints which enable you to turn your wheels smoothly. The CV stands for “constant velocity.” In essence, it’s a set of gears that connect a shaft that allows power from the transmission to be sent to the wheels.  When you turn the wheels, no matter what angle, the input velocity rotation will be equal to the output. Thus, the name, CV (constant velocity) joint. Other vehicles with 4-wheel drive and all-wheel drive also use CV joints.   If one of your CV joints isn’t working right, you may find your vehicle difficult to handle.  If one breaks, your vehicle may stop moving.  So, it’s important that CV joints be in top working condition.  The joints need a lot of lubrication, so they are surrounded by grease.  There’s a rubber enclosure around them called the boot which holds the grease in and protects CV joints from the elements.

If you have a vehicle with an automatic transmission, you probably never think about gear shifting.  When motor vehicles were invented, all of them had to be shifted manually.  But that wonderful self-shifting transmission, referred to these days as simply an “automatic,” changed everything. Automatic transmissions have a lot of moving parts, and they are bathed in a fluid that keeps them lubricated and cool. That fluid also is vital to the whole gear shifting process.  As you might imagine, the longer that fluid does its job, the more chance it has to pick up some contaminants.  Sometimes a leak will spring up in an automatic transmission.  Dirty transmission fluid or not enough of it will both create problems. It may cause your Check Engine light to come on, or your transmission may run rough and make strange noises. The best strategy is not to let it get to this point.  That means you should have your transmission fluid replaced at regular i ... read more

Ever wonder how your vehicle is able to move over bumps, potholes and other irregularities in the road and you hardly feel a vibration in the cabin? It’s your shocks and struts doing the hard work along with the rest of your suspension and tires.  They keep the ride smooth and are important for your vehicle’s safe operation.  So, how do you know when your shocks and struts are wearing out? One way is to look at the surface of your tire (where the rubber meets the road—where the tread is).  You might see some little indentations in certain spots, known as tire cupping.  If your vehicle takes longer to stop than it used to, takes a dive when you hit the brake pedal or bottoms out (scrapes) on a big bump in the road, that’s another sign, as are loud, odd noises. You may also notice your vehicle sways more than it used to. Every once in a while, look around at your shocks to see what shape things are in.  If you see the rubber cover cracked ... read more

So you almost got through the winter until, one day, your muffler started sounding like a dragster, loud and obnoxious.  It's not surprising.  All that road salt and brine can cause rust to punch holes in a muffler, and that should raise a big, red warning flag about the safety of your vehicle. One big concern is carbon monoxide, a poisonous gas that can drift into your cabin if your muffler is leaking. You've probably heard about people whose home furnaces have leaked carbon monoxide and overcome families inside.  Carbon monoxide can first cause you to feel dizzy and nauseous.  It can even render you  unconscious—even kill you.  So if your vehicle's muffler is leaking that gas, well, it's nothing to mess around with. Oh, and how about that noise? You may get a ticket since many municipalities have laws against noisy exhausts.  Your muffler may be making a clunking or rattling sound when the engine's running or it may be spewing thick exhaust sm ... read more

Most of us look forward to spring because the days are longer, the weather's warmer and we can finally get our vehicles into warm weather mode.  Here are a few things that will breathe fresh energy into anyone's car, SUV, truck or van. First thing is a good cleaning, especially underneath. If you live where salt and brine are used on the roads, it's important to get that off.  One thing to note… if you hose off your undercarriage, be careful not to get your spark plugs/wires wet.  You could notice your vehicle running rough plus the Check Engine light may come on. It usually dries out quickly, but if the engine light stays on for more than a couple of days, have your service facility check it out. Next, replace your windshield wipers.  They've taken a beating through the winter. New ones will have fresh rubber and you'll see clearly (and safely) out your windshield again. Have your brakes inspected.  That salt doesn't do your brake's metal components any ... read more

As your vehicle ages, its performance isn’t quite what it used to be, but many of us never notice the change because it’s gradual.  So here are a few questions to ask yourself.  Does your vehicle feel like it doesn’t have the pep that it used to? Have you noticed your fuel economy isn’t quite as good as it once was? Does it idle roughly or is it hard to start?  Do you hear the engine knocking? Has it recently failed an emissions test? All of those can be signs that your fuel and air induction systems are dirty and need cleaning.  Your fuel system takes gasoline from the tank to the engine’s combustion chambers where fuel injectors spray fuel that mixes with air and is ignited by spark plugs.  Black carbon deposits eventually can build up, obstructing fuel flow and diminishing your engine’s performance and fuel efficiency. The air induction system is what allows air to go into the engine’s combustion chamber.  Getti ... read more

Your vehicle’s engine runs hot.  It should, since it’s a series of little explosions that create the power that gets you going where you want to go.  To keep the engine cool, engineers have designed wonderful cooling systems that use liquid coolant, hoses, and a radiator to transfer the heat from the engine to the outside air.  In order for the system to work right, it has to have the right amount of that liquid coolant in it.  So that you know when the coolant has dipped below the correct amount, there is a sensor that keeps an eye on it.  When the coolant gets low, that sensor lights up a signal on the dash to alert you.  It may literally say “Check Coolant” or it may have a picture that looks like an old-style bulb thermometer sitting in liquid.  Your owner’s manual will usually tell you exactly what the one in your vehicle looks like. If that sensor system isn’t working right, you could wind up driving for a lo ... read more

It’s important for safe driving that two of the most important systems in your vehicle work right.  One is the brakes.  The other is the steering.  Nearly all vehicles on the road have some sort of power steering that allows you to direct a very heavy machine with little effort.  There are two types, hydraulic and electric.  Many newer vehicles have electric power steering that uses an electric motor to make your steering easier.  But there are many vehicles on the road that use a system that has been around for years.  It uses a power steering pump, a cylinder, several valves, and hydraulic fluid to make it easy for you to turn the wheel.  If you have hydraulic power steering in your vehicle, it’s important to change your power steering fluid every once in a while.  Over time, the fluid gets contaminated with dirt and other particles.  You might notice your steering is loose, maybe harder to turn and makes a low, strainin ... read more

As the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad.  But there's one more component to keep an especially sharp eye on during winter: your alternator. The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity.  That includes the battery, which needs charging to keep its power topped off.  The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity.  It is connected to the engine by belts and pulleys.  In cold weather, the material the belt is made from is less flexible than it is in warm weather.  That means it may not be turning the pulleys as effectively since it doesn't have the same grip. Also, when it's colder, lubricants, including the engine oil, are a little stiffer and parts just don't move ... read more
