Rumble from Down Under (Muffler Replacement)

We’ve all noticed them at one time or another on the street: a car or truck that drives by and the deep roar from their exhaust system sounds like a drag racer on the line.  But what happens when that rumble is coming from under YOUR vehicle? Well, it could be a sign your muffler needs attention.

You may notice other signs if your muffler needs to be replaced.  Your fuel economy may have plummeted, the smell of exhaust is blowing into your cabin, or your engine isn’t running in its usually smooth manner.  Or you may notice your vehicle’s temperature gauge is showing it’s running hotter than usual.

Mufflers sit under your vehicle, so they are exposed to all sorts of nasty things every day, and every season.  It may be dirt or salt from the road that gets kicked up on it, or you may rough it up with the potholes and speed bumps on the road.  Also, moisture from rain and snow combined with chemicals and brine can literally dissolve your muffler and other components of your exhaust system.

When you start to notice one or more of these signs, it’s time to head on over to have one of our technicians look at your exhaust system.  Under normal conditions, mufflers may last anywhere from five to seven years.  But when they start to go, to ensure your vehicle runs the way it should, you should have your muffler (and the rest of the components in the exhaust system) inspected and replaced if necessary.

Ideally, it makes sense to have your muffler and exhaust system inspected regularly when you have other routine maintenance done to your vehicle, such as oil changes and tire rotations.  That way, you can know sooner rather than later that your muffler is on its last legs before your (noisy) vehicle begins to draw the wrong kind of attention from other drivers.

Easy on the Wheel (Power Steering)

Steering a vehicle these days doesn't take much effort, but if you got behind the wheel back before power steering was invented, you'd need to practically have the strength of Hercules to turn the wheel.   

The first power steering systems widely available changed everything.  Chrysler introduced its Hydraguide power system in 1951. The "hydra" was for a hydraulic pump. It pressurized fluid that multiplied the force applied to the steering wheel so it was easier to turn the wheels on the ground. That pump got power from a belt attached to the engine, but unfortunately it wasted a lot of energy in the process. Plus, the system of hoses and pumps required a fair amount of maintenance and repair. Some say this system provides the most "natural" steering experience of power systems.

Recently, automakers have turned to electric power steering.  It gets its power from the car's electrical battery and charging system and uses an electric motor to turn the wheels.  Since it's not powered by the mechanical energy of your vehicle's engine, electric power steering increases fuel economy.  Electric power steering also doesn't require hoses and fluids, meaning there are fewer things that can go wrong.  That means less maintenance. 

There's a third system that combines both of the others, called electro-hydraulic power steering. In this system, the hydraulic power steering pump is powered by an electric motor and, some say, gives the driver that more natural feel of hydraulic systems.  

Because steering is so important for the safe operation of any vehicle, it's essential to make sure yours is working the way it should. Different types of systems require different kinds of upkeep. Regular, scheduled maintenance according to the manufacturer's recommendations should help keep your steering in top shape so you can avoid any sudden steering failures.  Bring your vehicle to us so a technician can inspect your steering system.  And, of course, if you notice any steering problems, make an appointment right away to have those issues looked at.  Now that's one stop that makes sense!

Why did my vehicle fail its emissions test?

We all want to breathe clean air and keep our planet green.  One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test.  That’s because these vehicles can be big polluters.  

Everyone wants their car to pass the test so they can continue their day-to-day driving routine.  But then comes that one day when they tell you your vehicle has failed.  Why does that happen?

One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!).  The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go.

Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air.  There are many reasons the catalytic converter may not be working.  It may be physically damaged, or the steady flow of exhaust gases has fouled the converter. 

You may have a bad oxygen sensor. It’s supposed to measure how much oxygen is in your exhaust.  This can cause the air-fuel mixture to be too rich, resulting in too many hydrocarbons in the exhaust. Your ignition system may also have problems, such as worn-out spark plugs.  Dirty fuel injectors can contribute to excess emissions.

Believe it or not, a dirty engine air filter may be the culprit. If it hasn’t been replaced for a while, your vehicle may be emitting too many hydrocarbons -  something that will cause your vehicle to fail the emissions test.

You can usually avoid a failed emissions test by maintaining your vehicle regularly.  The best way to do that is by bringing it to our trained technicians, so your vehicle gets the service it needs, scheduled and non-scheduled.  Plus, you’ll be doing your part to keep our air clean.

Oil Times are a-Changin' (Oil Change Synthetic)

When it comes to oil changes, things are really changing.  Most newer vehicles require synthetic oil, and while it costs more than conventional oil, it doesn't need to be changed as often.

When conventional oil was the only game in town, you changed your oil every 3,000 miles/5,000 km. But as technology in newer vehicles has rapidly changed, so has oil technology.  Synthetics have been around since the seventies.  Even though they start with a conventional oil base, they are engineered in a chemical processing plant with properties that allow them to keep your engine lubricated at very high temperatures.  They are more uniform and consistent.

Synthetic oil doesn't break down as easily, so it lasts longer than conventional oil.  And synthetic oil can flow more easily, even in extremely low temperatures.  As you can see, it has performance advantages at both temperature extremes.

Generally, in recent years automakers have been shipping most of their vehicles with either synthetic oil or a synthetic blend.  Blends are cheaper and have many of the advantages of synthetics.  Another reason synthetic oil is being used in many newer vehicles is its ability to flow more easily improves efficiency.   

It's important to follow your vehicle manufacturer's recommendations when you have your oil changed, so our service adviser can see what options you have for your vehicle. Many newer vehicles come with specific recommendations for synthetic oil. If you live in an area with wide temperature extremes or do a lot of stop-and-go driving, synthetic oil can offer advantages. 

Older vehicles can do fine with conventional oil, but it will have to be changed more than synthetic oil. Also, if you have an older vehicle with more than 75,000 miles/120,000 km on it, it can be more prone to leak and burn oil. Some synthetic oils are designed to protect those high-mileage vehicles better than conventional oil, and yours may benefit. See what your service adviser thinks.
