Hello, it's the Duke today. Are you conventional or synthetic when it comes to your oils?  It may be time to think about switching to the synthetic alternative.  Why, you ask? Well, today we'll bark about it and see what all the hype is about.  So let's get barkin' as I am not your conventional hound dog.

If you stay up-to-date on technology trends, you may be intrigued by synthetic motor oil.  It was introduced in the 1960s by Mobil.  Mobil's oil was different from conventional motor oil because it was first broken down to its basic molecules.  Then, Mobil removed additional impurities from crude oil and "tailored them to the demands of modern engines."

Synthetic oil is gaining popularity due to its advantages over conventional oil. It is more resistant to sludge formation in an engine.  It is more efficient and protects engines better in extreme temperatures.  Because it allows drivers to go longer between oil changes, many feel it's more convenient. 

The downside is that synthetic oil is more expensive; however, because it doesn't need to be changed as often, the cost can be comparable in the long run.

Those who drive high-performance vehicles (such as Audi, BMW, and Mercedes) are already using synthetic oil if they follow their manufacturer's guidelines.  Other manufacturers recommend a synthetic blend.  For those using conventional oil, consider consulting your service advisor for recommendations on switching to synthetic. 

If you're the type who always waits until the last minute or doesn't quite make it in on time for the recommended oil change interval, the longer gap required between changes with synthetic oil may appeal to you.  In some cases, you can go up to 15,000 miles/24,000 km between changes. 

If you drive in a frigid climate, synthetic oil can flow more easily at startup and may offer quicker engine protection.  On the other hand, in hot climates, synthetic oil can resist heat breakdown better.

Or you may be one of those drivers who have been getting along fine with conventional oil changes.  Millions do.  Remember that changing your oil is considered the most crucial maintenance task for your vehicle, so ensure it's done at the right time and with the oil that best suits your driving needs.

Today, I leave you with this conventional thought quote,

"Whenever you find yourself on the side of the majority, it is time to pause and reflect." ~ Mark Twain

Cayenne here, and I have a quick question for you.  Which is tougher on a vehicle's battery, the heat or the cold? Believe it or not, it's the heat.  Think about it.  The battery often sits in the engine compartment next to that motor, generating lots of heat.  That can accelerate corrosion in the battery and may even cause water in it to evaporate.  That will weaken your battery's cranking power and shorten its life span.

Here are a few suggestions for taking care of your battery.  It's a good idea to have it checked out to see what shape it's in.  Your vehicle service facility has diagnostic equipment that can evaluate its condition.  That can help you know how long you can expect it to last before replacing it.  At the same time, you should have your charging system evaluated.  If your battery is not getting charged correctly, it can be in great shape but not very useful when starting your vehicle.  A technician will also check the cable connections to ensure they are free of corrosion and tight.

Keep in mind that a vehicle battery can explode if it is close to an electrical spark under certain conditions. This is why it is safe to have a qualified, trained technician do the work. 

Your battery is essential in both hot and cold weather. Ensure it's always up to the job when starting your vehicle.

I leave you with my heat quote for the week,

Hello, it's a lovely day here in the Santa Clara Valley with Duke today. Have you ever thought about all the little things we do to keep our lives running smoothly - like  vacuuming? It makes a room feel fresher and more comfortable. We may not consider that we're also prolonging the life of the carpet by keeping it clean. But Los Altos drivers don't always extend those good habits into the garage. Our vehicles need regular maintenance, just like our rugs need vacuuming. We may not notice a difference in the feel or appearance of the vehicle, but just as cleaning a carpet carries the hidden reward of prolonging its life, maintaining our vehicles incurs a hidden reward that becomes noticeable at Los Altos gas stations.

When it comes to reduced fuel economy, there are two culprits: increased friction and inefficient fuel combustion. That means that anything Los Altos drivers can do to decrease friction and increase the efficiency of their engines will translate to savings on fuel. Friction increases the amount of energy it takes to move something. So, if we can reduce friction, we can decrease the amount of fuel it takes to run our vehicles. Engine oil is usually at the heart of friction problems in an engine. Too little oil means parts are not getting lubricated, which increases friction; dirty oil doesn't lubricate as well as clean oil. So, one secret to good fuel efficiency is to stay on top of oil changes. Don't skip them and don't procrastinate. The same auto advice applies to transmission fluid. Keep it full and keep it clean, and your vehicle will run with less friction and better fuel economy.

If your tires are underinflated, it increases the friction between the tire and the road. Again, there is increased drag, and it takes more fuel to move your vehicle. Los Altos drivers should check their tire pressure monthly and keep their tires properly inflated.

Alignment and brake problems can also increase friction. Besides saving fuel, keeping these systems in good repair has the added benefit of saving you on tires and brake pads. These items wear out more quickly when the alignment is off or when the brake system isn't in good working order. Talk to your friendly and knowledgeable service advisor at Allied Auto Works.

The second culprit that stealthily steals our gas is inefficient fuel combustion. It depends on the engine getting the right amount of clean fuel to the right place with the right pressure at the right time in the right pattern. The key to peak engine performance is to keep the fuel system clean. Varnish and gum can build up in a fuel system, which will interfere with the fuel injectors. The fuel injectors are responsible for all those “rights” we spoke of. If they're dirty, amounts, timing, pressure and spray patterns can all get out of whack. The result? Reduced fuel efficiency. A fuel system cleaning at Allied Auto Works in Los Altos can get your injectors back on track, improving performance and efficiency.

There are a few other maintenance items that can improve your fuel economy. One is to replace your PCV valve when it gets sticky. This valve allows unburned fuel in your engine exhaust to return to the engine. Los Altos drivers can also replace worn spark plugs and dirty fuel filters. A well-maintained vehicle will require fewer repairs and save at Los Altos gas pumps.

I leave you with this thought about cleaning today,

If you start me up, I'll never stop, so the lyrics go to the Rolling Stones: "Start Me Up."  Hi Cayenne here and well that's all good until your car doesn't start.    So yes, today we are going to start you up about ignition systems.  Let's get barkin'!

When you start up your gasoline engine car, you may not know it's using the same ignition principles as it has for decades.  You have spark plugs that require enough power so a spark can jump across a gap at its tip.  Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval, which is called timing.

The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off.  That higher voltage was then sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers.  Engineers later replaced the switching mechanism with solid-state ones, but they still needed replacement after 120,000 miles/200,000 kilometers.

The next evolution came in the 80's when the distributor was replaced with a couple of sensors that talked to a computer.  This "DIS" (distributor-less automotive ignition system) was a big advance.  Plus, it didn't use just one ignition coil for all the cylinders.  It had coil "packs" that each provided spark to two cylinders.  That way, the voltage could be boosted even higher, to 30,000 volts, which helped engines be able to ignite a leaner fuel/air mixture.

Even more improvements have recently come. Now, instead of coil packs, a coil is attached to each spark plug. No more spark plug wires means less maintenance. Plus, a stronger, hotter spark of 50,000 volts can make an engine more reliable, increase fuel economy, and reduce emissions.

No matter what ignition system your vehicle uses, your vehicle service facility has a staff of technicians trained to work with the latest technology. Make sure to maintain your vehicle regularly so you can fully take advantage of these modern engineering marvels.

Now that you have all the information, maybe these lyrics will stick.

The wheels on the bus go round and round until they don't......FLAT TIRE!  Hey, Duke here, and for most drivers, at some point, you’re going to have a flat tire. Depending on how it was damaged, it may have to be replaced.  But sometimes, a repair will do the trick, as long as the puncture isn’t on the sidewall and the hole is smaller than ¼ inch/6.35mm in diameter. Here are the three common ways your tire can be fixed so let's roll into it. 

One way is to put a plug in the hole.  Since most tires are damaged by running over sharp objects such as screws and nails, the small hole from which the air is escaping is on the part of the tire that touches the road. If it’s in the sidewall, it most likely can’t be fixed.  

In the plug method, a technician inserts a rubber plug.  It is covered with some sticky, gluey stuff and is pushed into the hole from the outside. That plugs the hole and stays in place, thanks to the glue. Friction from driving heats it and seals the deal.  

Another method is to patch the hole.  For this, your tire first has to be taken off the vehicle and then off the rim so the technician can get access to the inside. There, they’ll clean the inside surface around the hole and apply a rubber patch with an adhesive. This type of patch works well, and because of the extra steps and complexity, it costs more than having your tire plugged.  

There’s also a combination of those methods just described, the plug-patch.  It is, in essence, a type of patch with glue that has a plug sticking out of it.  The plug is inserted into the tire from the inside and pulled through the hole from the outside, drawing the attached patch tight against the tire’s inside surface. The last two methods can’t be used if the hole is near another repair or the sidewall.    

The good news is if it’s fixed properly, your repaired tire should give you good service.

I leave you with this flat tire quote,

Cayenne here, and you've heard the saying "get back to the daily grind," but what if the daily grind is your vehicle?????  Well, today, we will grind our way into barking about the question.  

If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you.  No, it is.  So listen to what it's saying and you could avoid a much more costly repair down the road.

A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on.  One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels.  Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. 

Think of it.  Hydraulic power steering has many components that need to work in tandem.  The power steering fluid may be too old and contaminated.  Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening.

Other causes of grinding while turning can be problems with the suspension in the front.  You may have a failing CV (constant velocity) joint.  It could be your brakes are partially engaging while you are turning.  That metal-on-metal sound is never a sign that things are working just the way they're supposed to.

To a technician looking to pinpoint the problem with your vehicle, it's not a daily grind at all.  Experience and training will help her or him zero in on what's causing the noise and get you back on the road. Maybe you can enjoy your sound system more after that distracting background noise has disappeared!

I leave you with this quote about the "grind"

"Nothing can substitute for just plain hard work."

Hey it's a beautiful day in the South Bay!  Duke here, and today is a great day for a car ride.  The sun is out, spring is around the corner and you can steer your way clear.....or can you?  So yes, today we are going to bark about our vehicle's steering and knowing when it's time to address this issue.  Let's steer ourselves into the conversation. 

Those who know vehicles believe the steering system may be the most vital component of them all. Perhaps you've found over the years, your steering has gotten loose. Or maybe suddenly, your steering wheel has gotten very hard to turn. Let's steer you in the direction of understanding why this may be happening.

First, loose steering. This can likely be the result of wear and tear on the components that connect the steering mechanism with the wheels. Those parts can be ball joints, Pitman arms or tie rods. These parts take a lot of abuse on the road, thanks to railroad tracks, potholes, uneven surfaces: you name it. It's important that they be checked regularly and maintained at Allied Auto Works.

Second, the hard-to-turn wheel. Virtually all vehicles on the road have power steering. However, there are a couple of different types, so let's deal with each. By the way, when they fail, your vehicle's steering can suddenly go from easy peasy to really hard to control.

Some vehicles have hydraulic power steering. It uses a hydraulic fluid that can either leak out or become contaminated. When that happens, you can lose that power assist. A belt's also involved, and if it becomes worn, stretched or cracked (or even breaks), you'll find yourself struggling with the wheel. If you hear a loud whine coming from the area in the engine compartment when you are steering, that could mean your power steering pump is failing. The best way to avoid these problems is regular maintenance.

Recently, manufacturers have been using electric power steering systems with advantages over hydraulic systems. They have electric motors that—like everything mechanical—can fail. Sometimes a fuse to the power steering motor will blow, but simply replacing the fuse often doesn't get to the root cause of the problem. A Allied Auto Works technician can evaluate the system and recommend a solution.

Steering issues are all about safety and should be addressed as soon as possible. When you tell your service advisor, try to be specific about the signs and symptoms. It's one way to steer clear of trouble on the road.

I leave you with this thought for the week,

Cayenne here, and it seems like we're hearing about more and more electric or hybrid vehicles.  Keep in mind that conventional gasoline internal combustion vehicles have important electrical components, too, and it's important to make sure they're operating at their peak.  So today, we will bark about who's in charge no matter what you drive: electric, hybrid or gas with alternator repair. 

In a vehicle with a gasoline engine, the part that keeps the battery charged is the alternator.  It converts the mechanical energy created by the engine into electrical power.  To do that, a shaft in the alternator has a pulley on one end that's driven by a belt that is turned by the engine.  A series of magnets then spins around coiled wires and it creates alternating current, or electricity. Your vehicle uses that to charge the battery that, in turn, keeps other electrical components in your vehicle working.

Here are a few signs that the alternator isn't doing its job right.  The battery keeps going dead, your instrument panel's battery light is on (it looks like a rectangle with a - and + inside and a couple of "terminals" on top), or your lights are dimmer than usual. You may also have a voltage gauge that shows lower than usual power. If bearings in your alternator are seizing up, you may hear a grinding noise coming from your engine compartment. If you have any of those signs, bring your vehicle to us so we can check your electrical system.

A technician will run diagnostics on your alternator, the cables and the battery. Because a belt drives the alternator, the technician will check the shape of all the drive belts.  Plus, we'll see how much electricity the alternator is putting out. 

If your alternator has failed, it can be replaced with a new or a remanufactured one. Speak with your service advisor about which will best suit your needs. Oh, and keep in mind that sometimes other parts may have to be replaced at the same time. For example, if your alternator's bearings froze up, that may have damaged the drive belt, and it may have to be replaced at the same time.

Hey, Duke here, and you know, everyday technology is changing, and so is the technology in our vehicles. Automotive design has come a long way since the days of the Model T, especially regarding safety technology.  You can thank computers for a lot of the latest innovations.  Here are a few that have been making their mark in recent years.

Adaptive cruise control.  This is cruise control with a brain.  Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops. 

Automatic emergency braking.  We've all been distracted while driving, and you've probably been in a situation where the driver ahead of you has suddenly stopped.  Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you.  (After all, there are a lot more distractions in your vehicle these days.)  New systems that use cameras, lasers and other types of sensors will warn you to start braking.  If you don't heed the warning, they'll put on the brakes for you. 

Blind spot warning.  We all worry about hitting a car approaching from behind and on either side if we change lanes.  Rearview mirrors cover some blind spots, but they're not foolproof.  Enter the blind spot warning system; it warns you with a noise or a light if a vehicle is in a place you might not be able to see.

Lane departure warning.  We all try to stay in our lane, but sometimes our attention wanders.  If you start to drift out of your lane, new warning systems using cameras and other sophisticated sensors will tell you to get back in your lane.  Some send an audible warning; others use a vibration or warning light. Some will even steer your vehicle back into the lane. 

Rearview camera.  There was a time when trucks and SUVs were involved in horrible accidents because the drivers couldn't see what was behind them as they backed up.  Children and pets were among the tragic victims.  Now, inexpensive rearview cameras are required in the U.S. and Canada, saving lives and providing much more peace of mind for drivers of vehicles with rear visibility issues. 

Ensuring this safety technology is working correctly for these systems to be effective is essential.  Your service facility can check and maintain these systems as the manufacturer recommends.

And for this week, I leave you with this technology quote,

Good day my South Bay Drivers, Cayenne here.  Have you ever met another person or dog, in my case, and they gave you bad vibes?  You know there is something not right about them.  Well, your car can do the same thing, throw off some bad vibes, and that isn't good.  So today, we will bark about disc brake rotors and the bad vibes they could be sending out.  

If you were to name the most important safety feature on your vehicle right now, what would your answer be? A lot of driving experts would agree that it’s your brakes.  Most newer vehicles use a well-engineered and efficient style of brakes called disc brakes. 

The name disc brakes comes from one of the components: a disc attached to the wheel hub that is squeezed by parts called calipers.  If you’ve ever ridden a bicycle with hand brakes, you probably have seen how they squeeze against the rim of the bike wheel to stop the bike. It’s similar to the way your vehicle’s calipers squeeze against the disc rotor, with added parts called brake pads attached to the calipers that create friction and stop your vehicle.

Here’s why disc brakes need regular maintenance.  Over time, that friction creates wear and tear on the brake pads and the rotors, and you’ll start to see the signs.  Your brakes may have one of the 3 “S” sounds: squeaking, squealing, or scraping. The sound is usually the first sign of brake pad wear, which can lead to rotor damage.  Soon, you may notice a pulsating or vibration when you brake. That’s because your once smooth and straight rotor disc is warping from the heat generated by friction. Or it may be due to wear.  Eventually, your brakes will take a longer distance to stop your vehicle, and the rotors can have grooves carved into them.

When you start noticing any of these signs, having them inspected by a trained technician is a good idea.  They will measure the rotor thickness, check wear patterns for grooves and heat discoloration, and see how much of the brake pads remain. They will also check to make sure all brake components are moving freely, check your brake fluid, and look for corrosion.

Most vehicle manufacturers require worn or damaged rotors to be replaced, not resurfaced. It’s all part of a complete brake job, replacing pads, brake hardware, and rotors. It reduces the chance of premature failure.

How often you need your brakes serviced depends on the manufacturer’s recommendations, your driving habits, and your environment.  Your service facility can recommend the best replacement parts based on those factors. 

Regular maintenance and attention are vital for keeping your brakes performing as designed. Remember, your brakes are your vehicle’s most important safety feature.

I leave you with this thought for this week,
