Motor Oil?The Synthetic Advantage (Synthetic oil vs Conventional)

You’ve probably already heard that regular oil changes are extremely important for the health of your vehicle’s engine. That’s sound advice.  But what you might not know is when it comes to motor oil, the real thing may not be the best thing for your engine.

There are different types of motor oil:

• Conventional oil, extracted from the ground and refined.
• Synthetic oil, manufactured from high-quality base oils and artificially-made chemical compounds.
• Synthetic oil blend, a mixture of conventional and synthetic oils.

The first thing you need to know is that most new engines require synthetic oil.  If synthetic oil is recommended for your car – you MUST use it.

For the rest, there are many advantages to using synthetic oil over conventional oil.

• Synthetic oil provides better protection for your engine while helping it to perform better.
• Conventional oil breaks down over time, while synthetic oil lasts longer.
• Synthetics can stand higher temperature extremes, both heat, and cold.

Synthetic oil can be a better choice if you live in an extremely hot or cold climate or put a lot of strain on your engine by towing or carrying heavy loads.  It also may be good for older engines that sometimes have a tendency to develop sludge.

Synthetic oil is a more expensive option, but you likely won’t have to have your oil changed as often.  Some synthetics are recommended to last 10,000-15,000 miles/16,000-24,000 km between changes.

You might also consider a synthetic blend that gives you some of the advantages of synthetic oil at a lower cost. Have a talk with your service adviser about recommendations for what will best suit your vehicle and driving habits.

It’s interesting to note that in recent years, more than one out of two vehicle owners are opting for synthetic oil or a synthetic blend when they get their oil changed. Sounds like they’re on to something. In the long run, if you have fewer oil changes with synthetics, you’ll use less oil, a bonus for our environment.

Bad Vibes

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something.

There are a few things that can cause your steering wheel to vibrate as you drive down the road.  One of the most common is out-of-balance tires.  You may not only feel that wobble in your steering wheel, you might also feel it in the tires.  Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds. 

So what is tire balance anyway?  Well, you have a rubber tire that fits around a metal wheel.  It should have the same weight all the way around.  If it doesn't, it will start getting the shakes.  Ever load your washing machine so that all the clothes are at one side of that drum that spins?  When it hits the spin cycle, it can throw that washer against the wall. 

That's the same thing that's happening with an out-of-balance tire/wheel combination.  A technician has special equipment to figure out where to put small weights on the wheel to get things back in balance again.  But it could be that you hit a pothole some time ago and bent the rim.  Or your tire isn't as round and even as it once was.  That could be due to age, damage or wear and tear. The technician will know and offer you options.

Another possibility for that vibrating wheel is a faulty brake, such as warped rotors or a sticky caliper.  All of these issues can be evaluated as part of regular, routine maintenance with us.  There are many things that cause vibrations in your wheels.  But you don't want any bad vibes when it comes to your vehicle. 

Greeted by a Screech (Loud Noise when Starting Vehicle)

No one likes to be greeted in the morning by having someone screech at you.  The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine.  If you're wondering if that's normal, no, it isn't.  And it is worth getting checked out.  The good news is that it might be nothing serious.  Then again, it may be.

The first things to suspect any time you hear a high-pitched sound coming from the engine are belts.  They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly.  The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix.

Other things that will cause a high-pitched sound are the pulleys and tensioners.  The tensioners keep the right amount of pressure on the belts and some pulleys contain rubber that dampens engine vibrations.  The rubber in the pulleys can crack or deform with age, which prevents them from working correctly and may cause your belts to wear out.

A technician will check to see if the belts are worn or cracked.  He or she will also check the tension on the belts, the condition of the pulleys and whether all  components are aligned the way they should be.

Sometimes, the noise is nothing major to worry about, but it's still worthwhile to rule out any problems that have cropped up now or may appear in the future.  You'll have a properly running vehicle that sounds like its engineers intended… quiet and smooth.

Your Vehicle is Talking to YOU (Service Warning Signs)

Your vehicle may be like that famous battery bunny, the one that just keeps going and going.  But while it may seem sometimes like you never need to take your vehicle in to be worked on, there are some things you should keep your eyes, ears and nose out for. They are warning you about something that needs attention at your vehicle service facility.

• If a warning light is on, don't ignore it; do something about it.  There are warning lights for battery, oil, engine heat, tire pressure… you name it.  And the manufacturer put them there for a reason.  They're telling you something isn't normal. So when one goes on, have it checked out soon, especially the blinking Check Engine light.  The earlier you have any warning light issue diagnosed, the more likely you are to avoid a more serious problem.
• If your vehicle is vibrating or shaking, it's not only annoying, it could signal trouble.  You can bet your vehicle didn't do that when it came out of the factory! If you can feel a vibration in the seat of your pants or shaking in the steering wheel, head on over to your service facility and have them diagnose what is causing it.
• Smoke coming out of anywhere in your vehicle is a signal (smoke signal, get it?) that there may be a troubling issue.  Likewise if you can smell something burning (like oil), the nose knows there's something amiss.  Time to find out what.
• If you aren't getting the distance you used to out of a tank of gas, it may not simply be your lead foot. A lot of vehicles will give you a digital readout of your latest mileage.  If your fuel economy takes a dip, take a trip over to your service facility.  You might have a sticky brake caliper… or it might be something as simple as your tires need more air.
• Yes, you know the dreaded puddle of something under your vehicle can be a bad sign.  It could smell sweet, it could feel oily.  But it means something is leaking.  Go get it checked.  Sooner is better when it comes to locating the source of a leak.
• If your brake pedal travels further than it used to while stopping, that could be compromising your ability to stop safely.  Also, if the brakes are making odd sounds, pulsating, grinding or squealing, they're screaming at you for attention.  Proper braking is a must for your safety and those drivers around you.

An old 80s TV show called "Knight Rider" featured a talking car.  You already have a vehicle that's telling you things all the time.  Give it a listen and it will keep you going safely down the road for many years to come.
