10 Things That Are Lowering Your Fuel Economy

Regardless of whatever current gas prices may be, if you could use less gas, wouldn’t you? Well, here are 10 things that are robbing you of better fuel economy that you can change for the better:

   •    Not enough air in your tires.  Underinflated tires have a smaller rolling diameter and more resistance to rolling.  Keep them inflated properly, plus ask us about more fuel-efficient tires.

   •    Faulty oxygen sensor.  A faulty or dirty oxygen sensor can cause your engine to burn too rich a mixture of air and fuel.  That can also trigger a Check Engine light.  Have us check yours.

   •    Oil age and type.  Contaminated or improper viscosities of engine oil can create more resistance in your engine.  Have regular oil changes and consider newer high-mileage oils.

   •    Bad wheel alignment.  When your wheels aren’t lined up straight, they have more resistance.  Let us check your alignment and straighten things out if necessary.

   •    Aging ignition system.  When’s the last time your spark plugs, spark plug wires and coils were changed? Misfires can rob you of good mileage.

   •    Dirty fuel injectors.  They can be inefficient if they’re not clean.  Have us check yours to make sure they’re working as they should.

   •    Fouled fuel filter. After filtering impurities out of your fuel, the filter may be clogged and affect your engine’s performance.

   •    Worn out or stuck brakes. This creates drag on the wheels and prevents you from rolling freely down the road.  Have us inspect yours to see how yours are.

   •    Worn piston rings.  These form a seal in the cylinder walls so you have top compression. When the seal is sloppy, down goes your fuel pressure and mileage.

   •    Poor maintenance.  If you don’t keep your engine’s systems running efficiently, they can nibble away at your fuel economy.  

Let us help you keep your eye on each one of these so you aren’t wasting money and gas.

A Most Important Part (Serpentine Belt Replacement)

Your vehicle’s engine is an engineering work of wonder with many complex parts working in harmony to get you down the road. One of those simple but important components is called a serpentine belt. It is driven by a pulley on the engine and transfers that power to many of your engine’s most important components.  The serpentine belt may drive the alternator, water pump, power steering pump and air conditioning compressor.  

When it’s working like it should, you won’t even notice the serpentine belt.  But when it starts to fail, you may hear a squealing noise coming from under the hood as the belt starts slipping.  Heat and time take their toll on the serpentine belt, causing it to crack or even to start shredding.  When this happens, it may not drive your alternator correctly, and your battery light may come on.  If the water pump isn’t turning, your engine may overheat, causing the heat gauge to show hotter than usual.

When the serpentine belt isn’t doing its job, it’s important to get it serviced very soon.  Letting it go too long can result in many more expensive repairs to multiple parts on your vehicle, especially if the belt breaks.  

Regular vehicle maintenance is important, and an inspection of your serpentine belt should be one of those things you should have one of our technicians do periodically.  While the belts can last for years, it’s important to detect any beginning of wear earlier rather than later.  In addition to the condition of the belt, the technician can also check to make sure pulleys are aligned properly and that the belt is routed correctly.  

Your vehicle’s serpentine belt is one of those components that you won’t even notice when it’s doing its job, and maintaining it will help you avoid surprises at the worst possible time.

(Ball Joint Replacement)

Every day that goes by, our bodies get a little more wear and tear on them.  Our vehicles have the same issue.  The older we get and the farther we travel, certain parts start showing some wear.  

Think of your hips. There are parts of our vehicles that are similar to them; just like hips allow your legs to pivot in several directions, your vehicle has similar parts called ball joints, and they connect your vehicle’s wheels to the suspension, allowing them to move together.  These ball joints get a good workout every time the vehicle is moving, especially on bumpy roads.  

Usually, these joints are well lubricated with grease, so they’ll work smoothly and quietly. They’re surrounded by a rubber sleeve called a boot, but that can wear out with age or exposure to moisture or debris.  When the rubber breaks, the grease can leak out, and damage accelerates.

When the ball joints start wearing out, you may start to hear clunking sounds that come from the corners of your vehicle.  You might hear it more clearly when you are turning a corner or going over a bump.  Over time, it might get worse.  Other signs are sloppy steering, vibrations when you’re moving and uneven tire wear.
If a ball joint gets extremely worn, it’s possible you can lose control of your vehicle, a dangerous situation indeed.

If you notice any of these symptoms, bring it to us so a technician can diagnose the problem.  If they determine you need a new ball joint, the technician will check the condition of all the suspension components.  We usually recommend if one of a pair of ball joints goes bad, the other is likely quite worn as well and should be replaced, too. In no time, you’ll be back on the road with an updated agile suspension that feels young again.

Ball Joint Replacement

Think about this the next time you’re driving.  Your front wheels can steer your vehicle and, at the same time, the wheels can move, even with all the irregularities in the road moving them up, down and in different directions. Pretty amazing engineering, wouldn’t you say?

What allows that are parts called ball joints.  Most vehicles have them only in the front, but there are some vehicles that have them in the rear as well.  When you consider all the bumps and turns your wheels are subjected to, it’s not hard to imagine the wear and tear these ball joints endure. After any vehicle has put on many months of road time, these ball joints will start to wear out. 

You may find your vehicle’s front wheels clunk when you are on the road, it may not hold the road as well when you go over a bump, or you may feel vibration in your steering wheel and your tires may start to wear unevenly.

When you start to notice any of these symptoms, it’s a good idea to bring it in to have one of our technicians look at what’s going on. If you keep driving with worn out ball joints, you can cause your tires to wear out more quickly.  And if you go even longer, you might find your suspension can collapse, meaning you won’t be able to keep your vehicle under control.  

Many vehicles have upper and lower ball joints, depending on what kind you are driving.  The upper ball joints usually don’t bear any weight while the lower ones do.

When our technician replaces your ball joints, they’ll take your wheels off, then remove the control arm(s).  After replacing the ball joints, they’ll inspect the rest of your suspension to make sure there aren’t any other components that need attention. In some cases, you’ll also need to have your wheels aligned after this service. 

So, when you hear those clunks or feel those vibrations, they may be signs your steering and control over your vehicle aren’t as good as they need to be for dependable, safe driving.  Heed the warning signs and keep your steering and suspension performing the way they’re designed to.

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.
