Bump in the Road (Alignment)

There's something you can do that helps your tires last longer, wear more evenly and your vehicle handle better.  "Sign me up," you say! Wondering what that is? It's aligning your wheels, and it will literally point you in the right direction when it comes to a better and safer driving experience.

When your vehicle was designed, the engineers made sure your tires were all pointing the same way by designing the suspension to make optimal contact with the road. That way the ride is smooth, you don't feel vibrations or shimmying and your vehicle travels in a straight line, without pulling to one side or the other.

Unfortunately, your vehicle is not brand new; time and distance take their toll.  After hitting countless bumps, potholes, or the occasional curb, your suspension gets knocked a little out of kilter.  Those precise angles the engineers planned on for your vehicle? They get out of whack

Uneven or premature tire wear is one of the first signs your alignment may be off.  If you are driving straight and your steering wheel isn't pointing straight, that's another indication alignment might need checking. Tire squealing can also be a clue.

When you bring your vehicle in for an alignment, we use equipment designed to measure the tilts and angles of your suspension's parts.  The technician will also check to see if any of the vehicle's suspension components are worn or broken.  We will also check your steering angle sensor to make sure it's set properly. 

The process is different for vehicles that are front-wheel drive, rear-wheel drive, all-wheel drive, or 4-wheel drive. 

After your alignment, your tires should wear more evenly, your steering should be straight and your wheels vibration-free.  If it's been a while since you've had your vehicle aligned, bring it in and we'll check it.  Usually, your alignment will be a little off after one or two years of driving, and it's wise to follow your vehicle manufacturer's recommendation for how often your model should be checked.

It's (Not) Complicated (Engine Air Filter)

While many components of your vehicle are complex and composed of lots of mechanical and electrical parts, there's one that isn't complicated but still important.  It's your engine air filter.

(And, we should point out, the engine air filter isn't to be confused with the cabin air filter.  The cabin air filter cleans air that goes into the passenger compartment while the engine air filter cleans air that goes into the engine itself.)

Why does your engine need a filter? Think of all the stuff–dirt, dust, and debris in the air¬–that gets kicked up on the road.  If that were to go unfiltered into your engine, it could damage other components.

There are many different materials used in an engine air filter, including paper, cloth (frequently cotton), and other synthetic fabrics.  The material is usually folded tightly to maximize the filtering capability over a relatively small surface.  

Before computers were employed to determine the proper mix of air and gasoline, a dirty air filter could contribute to a decline in fuel economy.  But a study of engine air filters done by the U.S. Department of Energy in 2009 found that in modern fuel-injected engines, computers can maintain the correct air/fuel mix even when an engine air filter is really dirty, minimizing effects on fuel economy.

That same clogged air filter, though, can affect your vehicle's performance, mainly how much power and acceleration it delivers.  In testing three different vehicles, a dirty air filter made the vehicles slower by about 6-12%.  That's something you'd definitely notice if you were driving.

But it happens slowly, over the course of several months, so you might not even know your engine air filter is dirty unless you bring it to us and have a technician inspect yours.  

There are many different types of engine air filters, from the ones made by the original vehicle manufacturer to aftermarket ones.  Some can increase your engine's performance; some can be washed and re-used but are generally more expensive.

Your service advisor can recommend several options for you, depending on the type of vehicle you drive and your driving habits.  Dirty, dusty roads will require more frequent engine air filter changes than cleaner drive routes, and each vehicle manufacturer recommends when your filter should be changed.  Keeping it clean will help your engine breathe a little bit easier.

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.

Making Sense of the O2 Sensor (Oxygen Sensor Replacement)

As you know, today’s vehicles rely on a lot of computers in them to keep them running clean and efficiently.  Those computers depend on information delivered by several sensors throughout the engine and exhaust system.  And one of the most important is the oxygen sensor.  

Known as the O2 sensor for short, it looks for too much unburned oxygen that has made it into the exhaust. That signals something isn’t right with the engine’s air-fuel mixture.  The sensor sends signals to the engine’s computers, which can then make adjustments to make sure the engine is running as it was designed to.

Some vehicles can have several O2 sensors, and since they can measure oxygen at various points in the combustion/exhaust process, the computers can pinpoint where the problems lie.  For example, an O2 sensor can detect how much oxygen is coming out of the engine’s combustion chamber, and another one can measure oxygen coming out of the catalytic converter.

As you can see, it’s important that those O2 sensors are working correctly.  If they’re not, the computer is getting bad information.  Garbage in, garbage out. That can result in lousy fuel economy and excess pollution coming out of your tailpipe. It can also affect your vehicle’s performance.  Sometimes your Check Engine light will illuminate when one of your O2 sensors goes bad.  Or you may notice your engine misfiring or idling roughly. 

If you notice any of these symptoms, bring your vehicle on in, and a technician will pinpoint the trouble spot.
