Los Altos Auto Repair

Good Day, it is Super Slick Cayenne and we are talking synthetic oils today, 

When you get an oil change, it’s always a safe bet to just use the type of oil the car maker recommends. But sometimes we’re asked if we’d like conventional or synthetic motor oil. We glance at the price tags on the two options and choose the cheaper one. But in this case, the more expensive oil might be the better bargain for Los Altos auto owners.

Conventional oil is made from petroleum. Its molecules form long hydrocarbon chains. Synthetic motor oil is either more highly refined petroleum or completely man-made. Its molecules are more uniform. This provides vital advantages over conventional motor oil.

First of all, the molecular structure of synthetic motor oil makes it more slippery than conventional oil so it lubricates better. This translates to better wear protection for Los Altos drivers, cooler operating temperatures, more engine power and increased fuel economy.

Further, synthetic oil is more heat-resistant than conventional oil, and it doesn’t vaporize as easily. It provides better protection for severe conditions like stop-and-go driving around Los Altos and very hot or freezing CA temperatures.

Also, synthetic oil doesn’t generate harmful oil sludge like conventional oil. This prevents small engine passageways from becoming clogged, which can significantly extend the working life of your sedan engine.

Manufacturers are aware of the advantages of synthetic oil, and many of them are using it to fill their sedans before delivering them to be sold. Many car maker's owner’s manuals now come with the recommendation to use only synthetic oil. Because synthetic oil wears better and protects better than conventional motor oil, it can be changed less often. If your sedan came with a recommendation for synthetic oil, you may have noticed that the recommended period between oil changes is longer than what you’re used to. However, if you switch to conventional oil, you need to be aware that you can’t follow this longer service interval. You’ll have to change your oil more often.

On the other hand, if you are using conventional oil and you switch to synthetic oil, you may be able to lengthen the time between oil changes. You can communicate with your personal and trust Allied Auto Works service specialist. He can offer you good auto advice about oils and service intervals based on your driving habits and requirements.

Oil changes are the hallmark of vital preventive maintenance at Allied Auto Works. All Los Altos auto owners need them. So we should get excited about a product that reduces how often we need them. Synthetic oil is more pricey, yes, but it can pay for itself by lasting longer than conventional oil. And when you add in the hidden savings of an extended engine life and improved fuel economy, not to mention increased engine power, there’s a good chance that synthetic oil actually saves in the long run. All Los Altos auto owners pay for car care. But understanding what we’re paying for can make us more savvy shoppers.

Til next time, this is Cayenne and I'm slicking out of here.

Good Day, it is Cayenne and we are barking about the right fluids for your vehicle.

Los Altos drivers' current vehicles have over a century of engineering behind them. They have evolved into complex and powerful machines. Developments in their engines, however, have coincided with advances in many other vehicle components, including the fluids.

It’s critical for Los Altos motorists to always use the right type of fluid for their sedan. Your service advisor and your owner’s manual are resources for auto advice on exactly what types of fluid your vehicle needs. Improper fluids can damage your vehicle and void your warranty.

Some of the fluids that have changed significantly in recent years are cooling system fluid, brake fluid, transmission fluid and motor oil. Each of these comes in many varieties now, and it’s critical to know exactly which one your sedan needs.

Cooling systems were once made of iron, steel and rubber. One coolant could be used to protect all of these materials. But new cooling systems have components made from a variety of metal alloys and several kinds of plastic, and coolants now contain additives that protect these various materials from corrosion. Since the materials vary among vehicle manufacturers, they require different additives, which means there are now a number of coolants on the market. The type of coolant your sedan needs depends on the materials used in its cooling system.

Most vehicles used to require Dot 3 brake fluid. But now many vehicles need Dot 4 or Dot 5. Some Los Altos motorists mistakenly think the higher numbers reflect an increase in grade—that Dot 4 is somehow better than Dot 3. But the truth is, the numbers represent variations in formulation. The different formulas have evolved to meet the demands of newer and better brake systems. For a long time, transmission fluid came in two varieties: regular and friction-modified. But transmissions have come a long way recently, and so have the fluids that protect and lubricate them. There are several new types of fluid on the market, but your sedan is designed for just one of them.

Of all the automotive fluids, motor oils have experienced perhaps the greatest advances in engineering and technology. A number of new weights and formulations have recently been developed to meet the needs of modern engines, which have more parts and tighter tolerances than ever before. Engines have become more sophisticated and complicated, but they have also increased in power and fuel efficiency. Despite these changes, Los Altos auto owners still need them to be highly durable.

That’s the job of motor oil. Motor oil still has to perform its original, vital function—lubricating and protecting the engine. It is formulated to help clean the engine as well. Modern motor oil also has to be thin enough to penetrate small engine passages yet still be resistant to vaporization.

Specialized motor oils have also been developed for high-mileage vehicles. If your sedan has 75,000 miles or more on it, you might consider switching to one of these motor oils. They contain extra detergents that help clean older engines and key additives that condition seals and gaskets that can become brittle with age. High-mileage motor oils come in weights and types just like regular motor oils, and Los Altos car owners should match the proper weight and type of high-mileage oil to their vehicle in the same way you would regular motor oil.

Over time, vehicles have developed in complexity and variety, and their fluids have developed as well. Each vehicle is matched to a set of fluids that meet its specific requirements. CA vehicle owners should take care to learn their sedan’s fluid requirements before topping off at home. A large part of preventive maintenance for Los Altos auto owners is making sure your vehicle’s fluids are clean and adequate, but they must be the proper type as well. As our sedans become more sophisticated, car care becomes more sophisticated as well.

Learning about proper fluids for your vehicle will help you maintain its performance and prolong its life. Talk or bark to us at Allied Auto Works in Los Altos.

Have a great day,

Cayenne

Hi it is Cayenne and we are barking fluids today.  

All those automotive fluids can be confusing for Los Altos car owners. Recent years have brought new grades of engine oil, types of transmission fluid, coolant, and brake fluid. The right fluid protects your vehicle and helps it perform at its best. The wrong fluid won’t work as well for Los Altos motorists and could even cause damage.

In addition to new grades of engine oil, many sedans now leave the factory with synthetic oil. Los Altos motorists should always use the recommended grade and type of oil in their engine.

All coolant, also called antifreeze, used to be green. Now there are several other colors of coolant sold at Allied Auto Works in Los Altos. Each type is designed to protect the cooling system components that are particular to your vehicle. The wrong stuff can void your sedan cooling system warranty and could even cause engine damage.

Most passenger vehicles on Los Altos roads today use either DOT 3, DOT 4 or DOT 5 brake fluid. Your sedan power brake system is specifically designed to use ONE of these types – you need the right one. Higher numbers do not necessarily mean a higher, upgraded fluid.

Now, the vital thing is knowing that your vehicle requires specific grades and types of fluids and that using the right fluids is good and using the wrong ones is bad. Once you’ve got that down, it’s easy to remember to check with your personal and trust Allied Auto Works service professional or sedan owner’s manual to find out which automotive fluids to use.

If you've walked through the automotive fluids of an auto parts store in Los Altos, you'll know how overwhelming the sheer number of products available can be. How do you know what's right for your vehicle?

As you know, these fluids all serve a function in making your car run as you drive around the Los Altos area. Your vehicle manufacturer has specified a particular type of fluid for every system from the motor, to the cooling system, brake fluid and so on. When you realize that not every variation is applicable to your vehicle, the task becomes more manageable.

First let's talk about why there are so many varieties. Starting with motor oil, we see that manufacturers match the properties of a particular weight or type of oil with the design needs of the engine. For example, engines with sophisticated valve trains often require a thinner weight of oil.

Some vehicles around Los Altos come from the factory filled with synthetic oil and the recommendation to use it for life. The safe bet is to always use what the factory recommends. The recommendation is what's been proven to work in function and durability tests. The recommended oil is also a factor in determining oil change interval schedules.

A good quality oil has more additives that are engineered to clean and protect the engine. They cost a bit more, but are worth the extra protection. If you buy budget oil, you might want to consider shortening your oil change interval.

Sometimes fluids are developed specifically to meet the needs of a particular family of engines. An example would be coolant. Because of the different materials used to build the cooling system, the coolant has to be formulated to protect those parts, which vary from manufacturer to manufacturer, from corrosion. We've seen special coolant in Los Altos for General Motors, Volkswagen, Chrysler and others.

The same is true of transmission fluid and brake fluid in recent years.

The really good news is that your Los Altos service center has databases that tell them the recommended fluids for your vehicle. This takes all the guess work out. If you have some special needs, like a higher mileage engine or want enhanced performance, ask your service advisor for upgrades or additives that'll meet your needs while being consistent with the manufacturer's recommendations.

Of course, your full-service oil change will top off your fluids. But it's a good idea to have some of everything at home in case you need to top something off yourself or to take on a trip. Ask your Los Altos service advisor at Allied Auto Works or check your owner's manual for fluid specifications.

It's important to know that there are national warranty laws that say that a manufacturer cannot require you to use their brand of fluid to maintain your warranty. That said, there are two things that may affect your warranty.

Using the wrong type of fluid may void the warranty. Going back to radiator coolant, the correct type protects against corrosion and the wrong type will not. So it's important to be right.

Also some warranty protections are conditioned on taking care of scheduled preventive maintenance. Please review your warranty if you have questions.

Today Allied Auto Works is talking about the proper fluids for your vehicle. It's become more complicated with changes in automotive design and manufacturing. It's not that people in CA are confused as much as they don't realize how much things have changed in recent years.

If you have questions about the fluids in your vehicle, please don't hesitate to stop by Allied Auto Works. You can find us on 2073 Grant Road in Los Altos, CA 94024.

Let's take engine oil. Twenty or thirty years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it's cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn't thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the car has been turned off for a while, the oil tends to run down to lower areas and the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It's certainly in the owner's manual. Of course, your Los Altos CA auto service center can look it up for you.

It's more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn't formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you're using the wrong coolant, your cooling system won't be covered under warrantee. So it's important to use the right coolant and to not mix different types.

Your owner's manual or your Los Altos CA service advisor at Allied Auto Works can make sure you're using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That's OK for an emergency top off, but following your manufacturer's recommendation for your sedan or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It's important to remember that the new ones aren't better than the old ones. They're just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid, and so on that contain additives to condition and restore seals and gaskets in older engines.

They're fine to use as long as they're a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it's also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it's the right type for your transmission.

The automotive professionals at Allied Auto Works would like to give Los Altos car owners an update on some of the things happening in automotive fluids. You know, cars are becoming more sophisticated everyday - and fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.

The Los Altos do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many CA car owners rely on the advice of their personal Allied Auto Works technician to not only get the correct family of fluids, but to suggest the formulation that is best for their car and their driving habits.

Let's start with engine oil. Cupertino car owners who have been paying attention, will have noticed a number of new oil weights on the CA scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. The auto makers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your Los Altos service center will know what weight your manufacturer recommends - and it's important to follow those recommendations. Your technician at Allied Auto Works can also offer suggestions for special formulations and can tell you all about conventional and synthetic oils.

Antifreeze, or engine coolant, is another area that has become more complicated. For a long time, car makers only recommended a couple of different types of coolant. Now, several different formulations are needed because of the high-tech materials that auto makers are using to build the cooling system. Using the wrong type of coolant can actually void your warranty, so you want to get that right.

Transmission fluid is becoming specialized as well. New transmission designs have particular requirements that require specific formulations. Recently, new, somewhat confusing, standards for brake fluid have also been released.

Not too long ago, there was a good chance that all of the vehicles at your Los Altos house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids you need will grow. And, some of the formulations will cost a little more. Fortunately, Allied Auto Works will continue to update their training to keep pace with technology so that you'll get the right fluids your car needs. It's all part of the commitment we make to your driving peace of mind.
