Hello Los Altos, Duke here, and California residents may have heard that vehicles don't need their oil changed as often as they used to. That's true. But it's not the whole story.  So today, I am going to answer, "What is the Risk of High Oil Change Intervals?"  So let's slip into this slick subject.

Owing to improved engine technology and higher oil quality, most newer vehicles can go longer between oil changes than their older counterparts.

So what is a good time interval for oil changes? How do CA residents know when to change it? And why do we change it in the first place?

Oil lubricates a vehicle's engine, which protects it from friction damage. Over time the oil can collect dirt and contaminants that inhibit its performance. But dirty oil isn't the only problem for CA residents. What you really want to avoid is called oil sludge.

Oil sludge is caused by moisture in the oil and by hot spots in your engine that burn off oil. This sludge is a gooey gel that can clog engine passageways, which can block lubricants from reaching vital engine parts. The result can be engine wear or even engine failure.

Sludge forms rapidly in an engine that is driven under what are termed “severe conditions.” A vehicle's owner's manual includes recommendations for oil change intervals under both normal and severe conditions. Severe conditions include towing a trailer, driving in polluted or dusty conditions, hauling heavy loads, or using a car top carrier. Also, extremes in climate, such as very hot or very cold temperatures, constitute severe conditions for vehicles.

Some people may be tempted to overlook the severe conditions preventive maintenance schedule in their 's owner's manual because of the word “severe.” But consider this: the most common form of severe conditions is stop-and-go driving, rush hour commuting, or only driving your vehicle on short trips around the area.

When a vehicle only makes trips under four miles/six kilometers or under 10 miles/16 kilometers in freezing conditions, the engine doesn't get warm enough for condensation in the oil to evaporate. The result? You get oil sludge build-up. If your driving patterns are the same as any of the conditions that count as severe, you should be changing your oil more frequently under the severe conditions schedule. 

The team at Allied Auto Works in Los Altos can help you understand what type of oil to use in your vehicle and how it can affect your oil change schedule. Some vehicles are filled with synthetic or synthetic-blend oil at the factory. The owner's manual will recommend that this oil continue to be used in the vehicle, and oil change intervals will be based on this type of oil.

Also, if your vehicle uses conventional oil, but you have some of those severe driving habits we talked about, you can switch to a premium-grade oil to give your vehicle extra protection. The answer to why we change our oil is fairly simple: to protect our engines and make our vehicles last longer and run better. But the answer to how often to change our oil is more complex: it depends on our vehicle, our driving habits, where we live, and what kind of oil we use.

When it comes to oil changes, a little information can go a long way to helping people save money and extend the life of their vehicles. Stay safe, and stay on the road.

Remember oil always be here for you

Hello Cayenne here on this beautiful summer day and I can see for miles and miles. If you're gonna drive around the Los Altos area, you've got to be able to see! So having a good set of windshield wipers is extremely important. We've all experienced the frustration and fear of not being able to see clearly during a storm or when our windshield is just dirty, especially with all the construction being built around town.  It gets on our windshield and blocks our beautiful view of California.  So today, we are going to wipe our windshields clean and bark about wiper blades.  Let's get barkin'!

It seems like your wiper blades are always at their worst when you need them the most. But windshield wipers are like most other vehicle parts– they require regular attention in order to work their best.

You really ought to replace your wiper blades twice a year, in the spring and the fall. If it's going to be a particularly harsh winter in CA, you may even want to get special winter blades in the fall. Winter blades are designed to resist freezing.

Speaking of winter and freezing conditions, if your car has been sitting for a long time and the windshield becomes frozen, don't use your wipers to clear off snow and ice. That'll just tear up the blades and cause them to wear out more quickly. It may even damage the wiper motor.

Over time, wiper blades become hard and brittle and then tear. They also lose their flexibility and just don't cover the windshield effectively.

Worn wiper blades aren't just a safety hazard; they can also scratch your windshield. That may require replacing the entire windshield, a big cost for such a little part.

Replace worn blades right away. Our professionals at Allied Auto Works can provide you with a quality replacement blade. They cost about the same as they would at the store, but installation is included at Allied Auto Works in Los Altos.

Of course, you also need windshield washer fluid to help your blades do their work. Even though Allied Auto Works will top off the washer fluid with a full-service oil change, it is a good idea to have some extra fluid at home or in the car if you are on a long trip.

Always use windshield washer fluid. Plain water, even that fancy bottled water, may freeze in the fluid reservoir or on the windshield itself, making things worse. Besides, water won't do a good job of cleaning your windows.

And remember that some vehicles have two reservoirs: one for the windshield and one for the back window, which may be under the hood or somewhere in the back.

So follow these tips to keep your windshield clear and your eye on the road, and give us a call.

A perfect summer day is when the sun is shining, the breeze is blowing, the birds are singing, and the lawn mower is broken. ~James Dent, in The Charleston Gazette, as quoted in The Reader's Digest, 1994

Duke here and I consider myself a handsome dog or as the ladies tell me I am one "Hot Dog".  Seriously though, some things can be too hot to handle and vehicle overheating is one of those HOT topics.  So today we will bark about Vehicle Overheating and make you feel, well more cool about it.  Let's get barkin'!

In the hot weather, seeing steam coming from the engine compartment is something we all dread.  No one wants that to happen to them. But if you know the signs of overheating and how to deal with it, you may be able to reduce the risk of damage to your vehicle, maybe even prevent getting stranded on the road.

Besides the steam coming out of the engine compartment, here are a few signs of overheating.  Your vehicle has a heat gauge that may have a needle that can go into a red zone or up to the "H" (for High) position.  You may smell odors, perhaps a burning (could be hot oil) or a sweet smell (engine coolant leaking). 

When you encounter any of those signs, you know you have to do something to keep the engine as cool as possible to avoid potentially catastrophic damage.  Turn off the air conditioning and turn up the heat.  While that last part may sound odd, it helps draw heat out of the engine. 

If you can do it safely, pull off the road to a spot away from traffic.  Turn off the engine so it can cool down for a few minutes.  You may want to call for help at this point, then switch on the key to "accessory" position to see if the engine has cooled down to the normal range.  You may have to have your car towed to a service facility or, if there's one nearby, you may be able to slowly drive to it.  But keep your eye on the heat gauge and immediately stop if it starts to overheat again. 

The best hedge against engine overheating is regular maintenance.  When the cooling system and other engine components are working like they should, your chances of an overheated engine are drastically reduced.  Your service facility will keep their eyes open for leaking hoses, cracked belts, rusted pipes and other things so they don't fail at the most inopportune time.

I leave you with my HOT joke for this week,

It’s so hot the cows are producing evaporated milk.

Hello, Cayenne here on a beautiful June day here in  Los Altos.  You know, some Los Altos drivers figure that anything they can attach to their trailer hitch can be towed by their vehicle, including my oversized t-bones. Well, that is not the case. If you're going to do any towing around Los Altos, you should be aware of safety issues, CA towing laws and potential liability.  So you probably already figured it out, we are going to bark about towing limits around town.  So let's get barkin'!

Understanding tow ratings is important for safe towing. A tow rating is the weight limit that your vehicle can safely tow. They calculate the tow rating for every vehicle, but different options on the vehicle can affect that rating. Los Altos drivers need to read the towing section in their owner's manual to get the specific tow rating for the vehicle they own.

Your trailer hitch also has a weight limit, and it may not match the tow rating for your vehicle. Your vehicle may be rated for 10,000 pounds (4,500 kg), but if you have a 2,000-pound (900 kg) hitch limit, you shouldn't be towing more than 2,000 pounds (900 kg). If you tow a 10,000-pound (4,500 kg) trailer on that hitch, it could break free and you would be liable for any resulting damages.

Another example is one popular pick-up truck that has a tow rating of 10,300 pounds (4,600kg). But the owner's manual specifies that a sway control device be used for trailers weighing over 2,000 pounds (900 kg) and that a weight-distributing hitch is required for trailers over 5,000 pounds (2,300 kg). If the vehicle owner tows a 6,000-pound (2700 kg) trailer without a weight-distributing hitch and ends up in an accident, the owner will be held liable for not complying with the towing requirements in CA.

Los Altos auto owners also need to keep in mind that tow weights include the weight of passengers and cargo inside the tow vehicle. So if your tow rating is 7,000 pounds (3,200 kg), and you're carrying 700 pounds (320 kg) of passengers and cargo, you can only tow a trailer weighing up to 6,300 pounds (2,880 kg).

Two numbers that Los Altos drivers should be aware of are the GVWR and the GCWR. These codes are usually imprinted on the inside of the driver's side door. GVWR stands for gross vehicle weight rating. Take GVWR and subtract the total weight of the vehicle, and you have the maximum weight the vehicle can safely carry in passengers and cargo. GCWR stands for Gross Combined Weight Rating. Take that number, subtract the weight of the tow vehicle and the trailer, and you have the maximum weight of passengers and cargo that the tow vehicle and trailer together can safely carry.

This may seem a bit complicated, but you ignore these ratings at your own peril. If you haul or tow loads over the maximum ratings around CA, you become liable in the event of an accident.

Local Los Altos laws require that safety chains be attached when towing a trailer. Some CA jurisdictions may require trailer brakes as well. Others mandate trailer brakes only in certain situations. If you are going to tow a trailer, you should find out the local Los Altos laws regarding trailer brakes and hitches, as well as weight and length restrictions.

To tow safely, CA drivers also need the proper tires on the tow vehicle. Tires need to be in good condition with adequate tread, and they need to have a load rating high enough to handle the weight of the trailer. Your trained Allied Auto Works tire professional can help you select the right tire to use when towing around Los Altos.

Your 's owner's manual is your primary source for auto advice regarding towing since it is specific to your vehicle. Be sure to read it carefully before doing any towing. And as always, keep your preventive maintenance up-to-date, and practice good car care to ensure the safety of your vehicle on the road—especially when pulling a trailer.

Here is my joke of the week, yes, tow related

If there was a film about a car towing a boat, would there be a trailer?

Duke here, and your vehicle requires plenty of clean fuel to run.  Today we will bark about keeping your vehicle's fuel clean.  So let's filter threw and get barkin" about clean fuel with a new fuel filter!

If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the Los Altos area. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

That's why all vehicles, including vehicles, come equipped with a fuel filter. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at Allied Auto Works in Los Altos.

If your fuel filter is clogged, the vehicle engine can't get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your vehicle engine running but doesn't protect it from contaminated fuel.

Los Altos drivers may find that they need to change their fuel filter at Allied Auto Works more frequently as their vehicle ages. Over the years, additional sediment and rust accumulate in the fuel tank and can be drawn into the fuel system.Your fuel filter stands guard at the gates to your engine to protect parts and maintain performance.  So make sure your filter is doing its job and book an appointment today!

For brakes sake, think of how much abuse your brakes take.  Hi Cayenne here and day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be. Then it's time to get your brakes checked out.  After all, you have to be able to stop if you want to be safe.  So let's get barkin' for brakes sake!

Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime.

Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate.

It used to be that rotors were thick, and when they warped, a technician could "turn" them to scrape off a layer of metal so their sides were straight again. The latest vehicles are using thinner, lighter rotors with a slightly different construction. Now, it's likely that rotors that are resurfaced this way will not have enough metal left to work safely. In fact, some manufacturers advise only replacing rotors that are worn out.

Newer designs have reduced rotor prices, and in many cases, the labor cost of turning the rotors is higher than buying new. There are times, though, when your rotors can be resurfaced and still meet manufacturer specifications.

If you have a rotor replaced on one side of your vehicle, it might be a good idea to replace rotors on the other side, too.

Maybe you're looking for the new rotors to last longer than the ones that were on there. New technologies can offer a longer lifespan in a premium rotor. Armed with knowing the type of driving you do, you and your Allied Auto Works service advisor can make the best decision on which direction you want to go with your new brakes.

Now that summer is here, I leave you with this quote.

Good Day, Duke here and you know we have all heard and maybe said the famous quote, "I'm beginning to see the light." but today, we really are dealing with seeing the light in our vehicle, the Check Engine Light.  So let's start barkin' and venture into the unknown of the Check Engine Light!

It's a light many drivers fear they'll see turn on at the most inopportune time.  It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine.

The truth is that the Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine.  Don't ignore it because it's there to help you avoid an expensive repair. It is designed to alert you, to tell you something's not quite right.

Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light.

If it's flashing, that could be serious. Look at some of the other warning lights or gauges, such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right away. In that case, if you can, safely pull off the road and shut the vehicle down. If your vehicle loses power and the Check Engine light is on, try not to push the demands you are making on the engine, such as towing or accelerating hard.

Simply put, a flashing Check Engine light should be checked out by a professional as soon as possible.

If the Check Engine light is on steadily, manufacturers say it means there's a problem, but it probably doesn't require immediate service.  The system is designed to remember the problem it found and store it (as a code) so it can be retrieved later.

When you do bring your vehicle in to have us see what's behind the Check Engine light coming on, we’ll hook your vehicle up to a diagnostics tool that can reveal the clues the engine's computers have stored.  It takes a trained technician to understand those clues, like a doctor who can interpret a patient's symptoms and come up with the correct diagnosis. Some newer vehicles can even be checked remotely.

Once we figure out the problem and repair it, you'll be back on the road again. It's nice to know the Check Engine light is your sentry, standing by to alert you the next time you begin to "see the light."

"I never cared much for moonlit skies

I never wink back at fireflies

But now that the stars are in your eyes

I'm beginning to see the light" ~Ella Fitzgerald

STOP, LISTEN, and LEARN!  I am putting on the brakes.  Hey, it's Cayenne, and I am barkin' about brake service today. So take a break, and let's bark about brake service.

When it comes to preventive maintenance and vehicle care, most Los Altos drivers know how important it is to check their brakes. But brakes are more than just brake pads and shoes. There are a lot of components in the brake system, and they all need to be in good working order.

The pads and shoes are known as the friction materials in the brake system. They push together, providing friction that stops the vehicle. It's no wonder they have to be checked regularly for wear, and brake pads and shoes need to be replaced periodically.

Brake pads/shoes gradually wear out, but that doesn't mean your braking gradually becomes less effective. The pads are engineered so that they maintain good braking until they wear too thin to provide adequate friction. At this point, they need to be replaced.

But your braking system also has mechanical parts. These pistons and springs can also gradually wear out or get gummed up by oil, dirt, and other road spatter. A brake inspection at Allied Auto Works in Los Altos includes a check of these parts as well as the pads and shoes. Your friendly and knowledgeable pros at Allied Auto Works can then advise you of any parts that need cleaning or replacement.

The fluid component to the brake system needs a regular check-up at Allied Auto Works as well. The brake fluid cools and protects your brake system. Protective additives are gradually depleted by the operation of the brake system, and moisture buildup inside the fluid can diminish its effectiveness. When you have your brakes serviced at Allied Auto Works in Los Altos, the fluid should be checked and, if needed, replaced, which will clean out water, debris, and dirt.

It is important to remember that your brake system also includes your tires. No matter how well your brake system is performing, if your vehicle tires are worn, you won't get good stopping power. Traction is the power of your tires gripping the roadway. Traction is always better on tires with good tread. Good traction translates to good braking.

This is particularly important on wet Los Altos roads. A good tire will give you good braking on either wet or dry CA roads. But stopping distance increases dramatically when worn tires meet wet roads. Tread on a tire acts to channel away water as the vehicle passes over the wet road, improving contact between the tire's surface and the road, which maintains traction. But the thinner the tread, the less effective the water channels become, and water can get between the tire and the roadway, reducing friction. A loss of friction means a longer stopping distance and possibly a loss of control.

Braking depends on two things: the weight of your vehicle and the speed of the vehicle. The heavier the vehicle or, the faster the vehicle, the more braking power it requires. Thus, brake systems vary from vehicle to vehicle. For example, a pickup that is designed for heavy loads has a more powerful braking system than a compact car. Sports cars also have higher-grade braking systems than minivans.

Regardless of what kind of car you drive in Los Altos, it is always good auto advice to keep your brake system in good repair, and that means ALL of your brake system. Just one more way to keep your travels accident- and worry-free.

Here is my brake joke for this week,

My mechanic tried to convince me that my car needs new brakes

But I know that it would just slow me down.

Cool Hound Duke here and today we want to talk about a system in our vehicles – the cooling system. It's one of those things that Los Altos auto owners don't give much thought to until it fails and then they're stranded by the side of a road in CA.  So let's stay cool and start barkin'!

Cooling systems fail more often than any other mechanical system – usually because of neglect. Don't you hate it when something breaks, and you could have done something to prevent it?

The good news is that if Los Altos drivers take care of their cooling systems, they can keep working for the life of their car.

Here at Allied Auto Works in Los Altos, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, thermostat, radiator, cooling fans, heater core, pressure cap, overflow tank, and hoses.

It sounds complicated, but we Los Altos residents don't have to be experts – we can leave that to our friendly and knowledgeable service advisor at Allied Auto Works. But, having an overview will help us remember how to take care of your car's cooling system.

Most Los Altos folks would be surprised to know that burning fuel in your engine produces up to 4,500 degrees F/2,500 degrees C of heat. And all that heat has to be dealt with. If the heat can't be drawn off the engine, the pistons will literally weld themselves to the inside of the cylinders – then you just have to throw the engine away and get a new one. That would cost thousands of dollars.

Now the water pump is what forces the coolant through passages in the vehicle engine to absorb heat. The pump is driven by a belt that needs replacement from time to time. And the water pump will eventually wear out and need to be replaced. Spending some cash on replacing the belts and water pump is much less than the cost of repairing the extremely massive damage that can be done when an engine seizes.

There's another little-known but important part of the coolant system that protects the engine. It's called a freeze plug. If you remember from high school chemistry, water expands when it freezes. In very cold areas, the coolant can actually freeze when the vehicle is left sitting.

It is hard to believe, but the expanding frozen coolant is enough to actually crack the engine block. The freeze plugs fit into the engine block. They fit tight enough to withstand the pressure of a running engine but can expand or pop out if the coolant freezes. These little things save a lot of engine blocks.

The team at Allied Auto Works can check your cooling system and make any necessary adjustments or repairs. Give them a call and tell Cool Hound Duke sent ya.

Here is my inspirational cool quote for the week,

Be who you are and say what you feel because those who mind don't matter and those who matter don't mind. Don't cry because it's over. Smile because it happened.  ~ Dr. Seuss

Cayenne here and today I am a little exhausted; exhaust system, that is. Did you know that your vehicle's exhaust system is more than just a tailpipe and a muffler? In fact, it is one of the most complex systems on your vehicle. So today, we are going to bark about service for your exhaust system.  Let's get the engines started!

The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless, and deadly. For this reason, it is important Los Altos residents keep their exhaust system in good repair.

The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.

The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn't require any regular maintenance, but it can wear out. If it fails, you will need a new catalytic converter to pass an emissions test in CA. Call Allied Auto Works at 650.968.7227 if you suspect a problem with your catalytic converter.

Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the vehicle engine's computer keep the fuel-to-air mixture at optimal levels.

The muffler is also part of your vehicle exhaust system, but it deals with a different kind of emission. It keeps your vehicle from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.

It is important that damaged mufflers be replaced immediately at your Los Altos automotive service center, especially if they are leaking. Not only will the extra noise annoy your Los Altos neighbors, but a leaky muffler could also be serious.

The entire exhaust system is attached to your vehicle by hangers and clamps. These fasteners can rust, come loose, or break. The components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts, such as wires and hoses. These can melt, causing serious damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.

Caring for your vehicle exhaust system at Allied Auto Works yields cosmetic benefits like quieting your engine sounds, but also may impact your health and safety. Your life, or the life of a loved one, may actually be on the line.

Here is my exhaust joke for you this week,

I had a dream last night that I was a muffler...

I woke up exhausted...
