Los Altos Auto Repair

Since driving requirements and lifestyles differ among Los Altos motorists, sedan manufacturers publish two auto maintenance schedules: the regular schedule and the severe service schedule. Which schedule should you follow?
Here are some questions to ask yourself:  Says Cayenne.

Are most of your trips less than four miles?  Getting dog biscuits and such.
Are most of your trips less than 10 miles in below-zero CA temps?
Are most of your trips off-highway?  Yes full freedom for us dogs to run.
Do you drive often in dusty areas?
Do you regularly tow a trailer or carry heavy loads around Los Altos?
Do you drive in very hot or very cold CA weather?

Cayenne wants you to think about your typical week. Do you live by your nearest Los Altos freeway on-ramp and enjoy a non-stop commute to Los Altos or Cupertino? Or, do you drive the neighborhood car pool or to your local pet store in stop-and-go traffic on surface streets?

Take a look at your owner's manaual says Cayenne and suppose your owner’s manual says the severe service oil change recommendation is 3,000 miles and the standard recommendation is 5,000 miles. You know that you need to change the oil somewhere between 3,000 and 5,000 miles. Analyze your driving patterns and Los Altos weather and road conditions to determine which end of the spectrum you’re closer to.

Why should Los Altos auto owners care about this? Normal condensation causes moisture accumulation in the engine oil. Short trips around Los Altos or winter driving means that the engine doesn’t heat up enough for the moisture to evaporate. The water in the oil turns to oil sludge that clogs up your engine and doesn’t let the oil protect it adequately. That’s why CA drivers need to change their oil more often – to clean the sludge out before it causes problems.

Carrying heavy loads like dog kibble (with or without a trailer) in nice CA summer weather causes your engine and transmission to run at higher temperatures and with more stress. The fluids will break down more quickly. Additives that clean and prevent corrosion will be depleted sooner. Air pollution and dust cause fluids to get dirty faster. Ditto for filters. All of these things can lead to premature wear and eventual repairs, not to mention your gas mileage. If you want some expert advice,Cayenne suggests you talk with your personal and trusted Allied Auto Works advisor. We can help you restore your sedan to good working order and help you know the best schedule to follow.

Welcome to Cayenne's Weekly Blog. Before the recession hit, the median age for cars in the Los Altos CA area (zip code: 94024) was over nine years. And two-thirds had over 75,000 miles. Cayenne and  Allied Auto Works hear reports that those numbers continue to rise.

Cayenne recommends if you have a high-mileage vehicle in the Los Altos area, bring it in for high-mileage maintenance:

Many people in Los Altos are keeping their vehicles longer. The economy has influenced that, but the fact that modern sedans are more durable and reliable means that owning a high mileage vehicle doesn't have to be a painful experience.

Local car owners in Los Altos with over 100,000 miles on their vehicles often ask Cayenne which service intervals they should follow. Cayenne's advice starts with the special needs of the older vehicle...

The reality is that time and mileage will take its toll. The engine and transmission will have more sludge. The fuel, steering and brake systems will have gum and varnish built up. There'll be more dirt and contaminants in the fuel tank. Corrosion and deposits in the cooling system. And seals and gaskets will start to dry out.

All of this, plus normal wear and tear, means that the engine might not be as strong as new, so it just has to work harder to get the job done.

So we need to compensate. Consider high-mileage formulations for oil changes, transmission service, etc. These special formulations contain additives that condition the seals and gaskets to prevent leaks. They also have more detergents to clean sludge and other deposits. They cost a bit more, but they're worth it.

In general, if an auto service was recommended every 15,000 miles when the car was new, you should continue to get the service done every 15,000 miles.

Cayenne recommends talking with your Los Altos service advisor at Allied Auto Works about the condition of your engine. See if he thinks you should adjust your auto service intervals for oil changes or other auto maintenance to account for the older engine working harder.

Expect the oil filter to get dirty faster. Same goes for the fuel filter. And some leaks are to be expected so you need to keep a closer eye on fluid levels.

If anything, following recommended service intervals for your sedan is more important in a higher mileage vehicle. Skipping oil changes or other services can lead to problems much more quickly than with a newer vehicle.

So, have your Los Altos auto service advisor at Allied Auto Works help you with an assessment of your older car or truck. If you haven't gotten around to a fuel system cleaning, or replacing power steering or brake fluid, a differential service or transmission service – it's time to start taking care of those things. It'll help keep you on the road for many more happy miles and happy dogs hanging out of the window Cayenne's says.  "We love our car rides!"

New cars cost so much these days. Add financing and insurance and, well a new vehicle may not seem so attractive. A lot of Los Altos, CA people are hoping to make their cars last a lot longer.

The good news is that with the current state of automotive engineering and manufacture, there’s no reason a modern vehicle can’t be made to last for a 150,000 miles or more.

There is an old saying that says, 'a stitch in time saves nine' and that is really true when it comes to taking care of your car. A great example is coolant service.

Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That’s why you need to have your cooling system serviced on a regular schedule.

The same is true for your power steering system, brake fluid, air conditioning system, differential and transmission. And your oil changes should be done right on schedule to avoid the build up of harmful oil sludge.

Don't let your brake pads go too long before they are worn to the point that they cause damage to rotors. Preventive maintenance is a great way to keep your operating costs down.

Replacing belts and hoses is much cheaper than repairing the damage that can be caused by failure.

Now this is a lot to remember. Allied Auto Works can keep on top of this stuff. We can tell you what your manufacturer recommends and help you with a plan to take care of it.

Bottom line – take care of this stuff on schedule and you will reduce operating costs, prevent costly damage and maintain your warranty coverage. Call Allied Auto Works today for an appointment; you can reach us at 650.968.7227.

Take good care of your car, and it’ll take good care of you.

A lot of Los Altos motorists have asked whether or not they should use their severe service maintenance schedule, which is listed in their car owners' manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for 24 years and is a speaker, a trainer, and a writer.

Cricket says there's so much confusion on this topic because, "Most owners' manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service'. Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement, and transmission service be done more often: either in fewer miles or in less time."

Foreign and domestic car makers create a specific schedule for each vehicle they manufacture. So there isn't one generic schedule that applies to all cars. In addition to your owners' manual, Los Altos automotive repair centers (including Allied Auto Works) subscribe to information services that provide the maintenance schedules for every vehicle - so they can help you know when to take care of needed services. Below is a typical definition for severe service.

• Most trips are less than four miles
• Most trips are less than ten miles and outside temperatures are below freezing
• You drive regularly in very hot CA weather
• The engine is at low speed most of the time (not on the expressway)
• Stop and go driving
• You drive in in dusty or muddy conditions
• You routinely tow a trailer, haul heavy loads or carry a car-top carrier

It's common sense: Just a few minutes at expressway speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than ten miles when it's very cold in Los Altos, don't allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to break down faster. Dusty and muddy driving means that more dirt will get past the air filter to contaminate the fuel system and engine oil.

The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving habits. Look at your owners' manual, or talk with your Allied Auto Works service advisor who can help you know which schedule to follow. Allied Auto Works is located at 2073 Grant Road, Los Altos CA.

Here is what a fleet manager said recently: "Since city miles are generally tougher on vehicles than highway miles, we use the manufacturer's severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science."

Make an honest evaluation of your driving habits. Unless you do mostly CA highway driving in moderate weather, you'll likely have a fairly good amount of severe service mixed in. Some Los Altos motorists just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.

Your minivan engine really needs clean air to operate efficiently. Let’s go egghead for a minute. For every gallon of gas we burn driving around Los Altos, twenty pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce twenty pounds of carbon dioxide?

The answer is that the carbon comes from the gasoline, but the oxygen comes from the air. You see, it takes about twelve thousand gallons of air to burn a gallon of gas in your engine. Clearly, your minivan needs a lot of air to keep going in Los Altos. A lot of clean air is better.

You’ve seen the pictures of the crowds in Asia wearing face masks. They want some kind of filter to keep unwanted pollution and germs out of their lungs. Well, your minivan also works better when its internals are clean. When your minivan air filter’s dirty, it simply can’t trap any more dirt, so the dirt just passes through into your air intake system. From there it can clog your fuel injectors and even get into the engine itself. And burning dust and pollen in your minivan engine does you no good.

So, we’re talking potential damage for Los Altos drivers. But another big thing is wasted fuel. Your minivan engine management computer tries to mix the correct amount of air in with the fuel. If the filter’s clogged, there isn’t enough air for the optimal fuel to air mix and that really messes with fuel efficiency.

In fact, replacing a dirty air filter at Allied Auto Works can improve your fuel economy in Los Altos by up to ten percent. At today’s fuel prices in Los Altos, you should be able to pay for a new air filter before your next oil change.

The verdict: When your minivan engine air filter needs to be replaced; it needs to be replaced. How often depends entirely on how dirty the air is where you drive in Los Altos. A simple visual inspection at Allied Auto Works will tell you when you need a new engine air filter.

When you look at the air filter on your furnace at home and see it’s all clogged up with dust and dirt, you don’t hesitate to replace it. When your Allied Auto Works technician brings out your nasty engine air filter, you now know why you should go ahead and change it out.
