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.

A "Mounting" Problem (Motor Mounts)

You know how heavy your engine and transmission are, so you can imagine how tough the parts that hold them onto your vehicle's sub-frame must be.  Not only must they support the weight, they also have to isolate vibrations and noise from the passenger cabin.  Pretty tall order, wouldn't you say?

The parts that face that task daily are called the motor mounts, or engine mounts.  They are usually made of rubber with steel brackets.  Others contain a liquid for vibration and sound isolation. 

Most vehicles have three or four motor mounts, and while rubber or hydraulic liquids do a good job of damping the vibrations from the engine, they also have their limitations.  The problem with rubber is that it gets old and brittle.  Plus, if there's an oil leak anywhere in your engine and oil gets on the rubber motor mounts, rubber will deteriorate even more quickly.  As for the liquid motor mounts, they can develop leaks and stop working. 

Here are signs a motor mount is going bad.  You may hear a loud clunking or banging sound under the hood.  That means the weight of the engine is shifting around enough to bang against other metal parts.  You may feel bad vibrations, and the engine may feel like it's moving around in a strange way.

When things get to that point, your vehicle can be damaged from that heavy engine knocking against things, and its time to replace one or more motor mounts.  Schedule a visit to your vehicle service facility. There, a technician will assess your motor mounts; if one bad one is found, it's not unusual that others are likely to fail soon and should be replaced before they do.

Because all vehicles are configured differently, some motor mounts are easily replaced.  But others can be much trickier, take a lot longer and therefore are more expensive to replace. 

It's important for your engine's health to make sure motor mounts are sound and solid.  You will maintain that quiet, vibration-free ride and could save your engine and transmission from major wear and tear.

Cold Weather Vehicle No-Nos (Items to Avoid Storing in a Freezing Vehicle)

It's always easier to leave a few things in your vehicle so you'll have them on hand.  But in cold weather, while it's a good idea to carry items such as a phone charger, blanket and shovel, there are some things you shouldn't store in your vehicle.

• Medicines and drugs.  Cold temperatures can affect the chemical makeup of some drugs.  Avoid leaving them in a vehicle, especially those in a liquid form like insulin, eye drops and cough syrup.
• Latex paint.  They are water based, and when they freeze, they get lumpy and lousy.  Your paint job will not be what you had in mind.
• Cellphones and computers.  Most of these have lithium ion batteries.  If they get colder than freezing (0 degrees C, 32 degrees F), if you try to charge them, you'll more than likely ruin the batteries. 
• Bottled water, soda, wine or beer.  OK, here's the scoop.  All of these can freeze and split the container they're in.  Yes, soda, wine and beer will take a lower temperature to freeze than water, but all of these can easily freeze if the mercury plunges low enough.  The problem isn't when they're frozen; it's when they unfreeze, drip out of their containers and leave you with a colossal mess. 
• Musical instruments.  Guitars are made of wood.  When a guitar freezes and you bring it quickly into a warm room, you may hear cracking sounds that tell you that guitar will be not-so-gently weeping from the damage that can occur.  The same goes for wind instruments and others.  Don't ever subject musical instruments to quick temperature extremes.

Take a little time and effort not to leave these things out in a frigid vehicle.  You'll likely spend far more time and money tending to the resulting consequences than if you'd just brought them inside in the first place.

Don't Do It Yourself (Perils of DIY Vehicle Repair)

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies. 

Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s.

Today's most highly-trained technicians are able to keep up with how to perform the latest repairs and service by continuing education about their craft.  When once an auto repairman could do fine with a lift and a good set of tools, now specialized electronic analysis equipment and tools are must-haves when it comes to vehicle repair.

Because of how fast technology changes, access to the latest repair databases and manuals is also important.  Manufacturers require certain service procedures to be performed precisely, and any other way can leave a vehicle compromised when it comes to performance and safety. 

Your vehicle is capable of traveling at high speeds on challenging surfaces with ever-increasing traffic issues and unpredictable obstacles.  You need your vehicle to be working up to its engineered potential.  That's why you should leave repairs and service to professionals.  They work on vehicles every day, and years of experience with hundreds of repairs equip them to deal with the unexpected as well as the routine. 

When you develop a trusting relationship with a reputable service facility, you can have confidence that the maintenance, service and repairs are being done by people who know what they're doing.  Your safety and your vehicle's performance and reliability are well worth it.

Such a Little Part (Climate Control Resistor)

You expect your heater/air conditioner to work like it should.  You have a control for temperature and one for fan speed.  You even have a control for what vents the air comes out of. 

Don't be surprised one day if your blower fan develops a mind of its own and starts going crazy.  Most of the time, you may find that it starts blowing at full speed, and nothing you do to try to control it does any good.  This is what may be happening.

Your blower motor has an electronic component called a resistor.  It does what its name says; it offers resistance.  When you want the fan to run more slowly, you turn the fan speed down.  That resistor accomplishes that by turning its resistance up.  When the resistor fails, the power has nothing to slow it and the fan speeds up. 

It's a small part and can fail due to age or corrosion.  It's usually not an expensive part, either, but it's often found in a location that's not that easy for the technician to get to.  That means labor costs will vary depending on the design of your vehicle. 

Occasionally, a faulty resistor can cause the blower motor not to work at all or only partially come on.  But other things can cause that as well, such as a faulty fan switch or vent control. 

This is where a technician's training comes in.  Special equipment can track down precisely where the issue is so you can be assured the correct part is being replaced.

It's just not pleasant when the blower motor isn't following orders.  Have your service facility check it out so you can be the blower's boss, like it should be.
