One might say the most challenging part of being an automotive service technician at Camarillo Car Care Center is diagnosing a problem before it can be fixed.
Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So, it's challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it's not something obvious, it's easy for the customer to focus on the fixing and not the diagnosing.
Let us at Camarillo Car Care Center introduce you to something we'll call 'Customer Detective Work' – helping your technician find clues to what's wrong.
We start with the detective basics: What, Where and When. Play along with me; You come in to Camarillo Car Care Center and your car is making a funny sound...
- Q: Where's the sound?
- A: Around the right front wheel.
- Q: What kind of sound?
- A: Kind of a clunk, clunk sound.
- Q: When do you hear the sound?
- A: When I turn and accelerate.
- Q: Right and left? Forward and back?
Do you see where we're going? You're gathering additional information to help your technician at Camarillo Car Care Center know where to start. Based on your car and the tech's experience, he'll know where to look and can start with the obvious suspects.
You can see how that would be more helpful than dropping the car off with a note that says "making a funny noise."
If the tech can experience the problem personally, he's better able to make a diagnosis and repair and then test to see if the repair solved the problem.

Since driving requirements and lifestyles differ among Camarillo drivers, your vehicle manufacturer publishes two auto maintenance schedules: the regular schedule and the severe service schedule. Which schedule should Camarillo drivers follow? Here are some questions to ask yourself:
Are most of your trips less than four miles/six kilometers around Camarillo?
Are most of your trips less than 10 miles/16 kilometers in below-zero CA temps?
Are most of your trips off-highway in CA?
Do you drive often in dusty Camarillo areas?
Do you regularly tow a trailer or carry heavy loads around Camarillo?
Do you drive in very hot or very cold CA weather?
Think about your typical week. Do you live by your nearest Camarillo on-ramp and enjoy a non-stop commute? Or, do you drive the neighborhood car pool in stop-and-go traffic on Camarillo surface streets?
Let's suppose your owner's manual says the severe service oil change recommendation is 3,000 miles/5,000 kilometers and the standard recommendation is 5,000 miles/8,000 kilometers. You know that you need to change the oil somewhere between 3,000 and 5,000 miles/5,000 and 8,000 kilometers. Analyze your driving patterns and Camarillo weather and road conditions to determine which end of the spectrum you're closer to.
Why should Camarillo residents care about this? Normal condensation causes moisture accumulation in the engine oil. Short trips around Camarillo 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 residents need to change their oil more often – to clean the sludge out before it causes problems.
Carrying heavy loads (with or without a trailer) in 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. If you want some expert advice, talk with your friendly and knowledgeable Camarillo Car Care Center service advisor. We can help you restore your vehicle to good working order and help you know the best schedule to follow.

Do you ever shop for shoes in one of our Camarillo area shoe stores?
When buying a running shoe, is quality important?
Does durability matter as long as the shoes look fabulous?
Would you rather have one pair of long lasting shoes or two pair of lower quality shoes at the same price?
Is the warranty important when buying tires?
When you choose new tires in Camarillo, what's the most important factor for you?
Give us a call at Camarillo Car Care Center at 805-482-2853 for tire recommendations.
You know, buying tires in Camarillo is a big deal. It's a big ticket item so you know you'll be spending a lot. You're not only concerned about the price, but you want to know that it'll be a long time before you need to buy new tires again.
And of course there's the safety aspect as well. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. They need to be up to the task. You want to be sure they hold the road and provide good traction. If you carry heavy loads or tow a trailer, the tires need a high load rating to be up for the job.
As a tire professional, I think it's important that people understand the effect of price on a tire's performance and durability. When I was a kid, my dad had a saying, "Pay twice as much and buy half as many."
Dad applied that to a lot of things. He thought that one high quality suit would last longer and look better than two cheap suits. The saying really seems to hold true when it comes to shoes and boots, too.
I buy high-quality work shoes because I spend a lot of time on my feet. They're more comfortable, have important safety features like steel toes and non-slip soles and they last at least twice as long as cheap shoes. I feel I get very good value for my money.
I apply the same thinking to tires. The major tire brands that you're familiar with are known as Tier 1 tires. These tires are well-engineered and very high quality. Comparable tires are usually in the same price range from brand to brand.
Stepping down in price you come to private label tires. Some large tire store chains carry tires with the chain's own brand. It's important to know that most private label tires are built by the same Tier 1 brands that you are familiar with, so they are a quality product. You can ask your tire professional who makes their private brand.
The lowest priced tires on the market are Tier 3 tires. These tend to be imported from China or South America. Since you get what you pay for, you can't expect a Tier 3 tire to deliver the same performance and durability as the others.
So let's say you need new tires. You've determined the features you need. So you have several options, including price options. Now, you've probably heard the term 'it's a 40,000 mile/64,000 km tire' or 'it's a 60,000 mile/97,000 km tire'. Simply put, the manufacturer warrantees the tire for 'X' number of miles/kilometers. If that's important to you, look for the warranty.
What's the difference in the tires with higher mileage warranties? It's the rubber compounds and the amount of tread material. As you might expect, you'll pay more for the longer-lasting tire.
Now the cheapest tires you can find won't have a manufacturer's mileage warranty, or if it does, it'll be relatively low. That brings us back to dad's saying; if you buy the cheapest Tier 3 tire you can, you will likely go through two sets in the time it would take to wear out one set of good quality tires. And the good tires won't cost twice as much, so you'll end up paying more per mile/km driven with the cheap tires.
Hey, I realize that sometimes the budget will only allow for a Tier 3 tire. I make them available for my customers who need them because I would rather see them driving with safe, new tires than pushing their old tires beyond their safety limits. But at Camarillo Car Care Center, we always counsel our customers to buy as much tire as they can afford, because it will be much less expensive in the long run.
Your tires are the only parts of your vehicle that touch the road. You're only as safe as your tires are well built.
Buy value – not price.

Hey Camarillo area drivers, are your tires worn out? What is the standard for our CA streets? How can you tell on your vehicle?
While there may be legal requirements for the Camarillo area, there are safety concerns that go beyond meeting minimum replacement mandates.
Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently.
We're referring to the tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.
In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.
A car and a full-sized pick-up accelerated to 70 miles per hour, or 112 kilometers an hour, and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths:
- New tire tread depth
- 4/32 of an inch, or 3.2 mm
- 2/32 of an inch, or 1.6 mm
So what happened with the 2/32 inch/1.6 mm tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 mph/89 kph. Stopping distance was nearly doubled to 379 feet/116 meters, and it took 5.9 seconds.
Wow! That means if you barely have room to stop with new tires, you would hit the car in front of you at 55 mph/89 kph with the worn tires.
Now, with the partially worn tires – at 4/32 of an inch, or 3.2 mm – the car was still going at 45 mph/72 kph at the point where new tires brought the car to a halt. It took nearly 100 feet, or about 30 meters, more room to stop and 1.2 seconds longer. That's a big improvement. We can see why Consumer Reports and others are calling for a new standard.
Of course, stopping distances were greater for the heavier pick-up truck.
How do you know when your tires are at 4/32 inch or 3.2 mm? Easy; just insert an American quarter into the tread. Put it in upside down. If the tread doesn't cover George Washington's hairline, it's time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.
You may remember doing that with pennies. A penny gives you 2/32 inch, or 1.6 mm, to Abraham Lincoln's head. The quarter is the new recommendation – 4/32 inch, or 3.2 mm.
How do people feel about replacing their tires earlier? Well, tires are a big ticket item and most people want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out?
For us, and we would guess for many, the answer is "no".

Have you ever had an experience like this in Camarillo, CA? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your Check Engine light starts flashing!
You fear the worst, but within a block or two, the light stops flashing, but stays on. By the next day, the light is off.
You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works.
Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage.
Warning, warning! It flashes the Check Engine light to alert you to take immediate action.
It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine control computer says the danger is past, but I'm still concerned, I'll keep this light on for now.
Then the Check Engine light goes off in a day or two.
The condition never did recur, so the computer says whatever it was, it's gone now. The danger is past, I'll turn that light off.
Now a flashing Check Engine light is serious. You need to get it into Camarillo Car Care Center as soon as possible. But if it stops flashing you can wait a few days, so you have time to see if the problem will clear itself or if you need to get it checked. How does the computer know when to clear itself?
Think of it this way. The engine control computer is the brain that can make adjustments to manage the engine. Things like alter the air-to- fuel mix, spark advance and so on. The computer relies on a series of sensors to get the information it needs to make decisions on what to do.
The computer knows what readings are in a normal range for various conditions. Get out of range, and it logs a trouble code and lights up the Check Engine warning.
The computer will then try to make adjustments if it can. If the computer can't compensate for the problem, the Check Engine light stays on.
The computer logs a trouble code. Some people think the code will tell the technician exactly what's wrong.
Actually, the code will tell the technician what sensor reading is out of parameters. It can't really tell him why, because there could be any number of causes.
Let's say you're feeling hot. You get your heat sensor out – a thermometer – put it under our tongue and in a minute or two you learn that you have a fever of 104 degrees F (40 degrees C).
You know your symptom – a fever – but you don't know what's causing it. Is it the flu, a sinus infection or appendicitis?
You need more information than just that one sensor reading. But it does give you a place to start and narrows down the possible problems.
There are reports on the internet telling you that you can just go down to an auto parts store and get them to read your trouble code or buy a cheap scan tool to do it yourself.
There are two problems with that. First, the computer stores some trouble codes in short term memory and some in permanent memory. Each manufacturer's computer stores generic trouble codes, but they also store codes that are specific to their brand.
A cheap, generic scan tool, like you can buy online or that the auto parts store uses, doesn't have the ability to retrieve long-term storage or manufacturer specific codes. Your Camarillo, CA, service center has spent a lot of money on high-end scan tools and software to do a deep retrieval of information from your engine control computer.
The second problem is that once you've got the information, do you know what to do with it? For example, a very common trouble code comes up when the reading on the oxygen sensor is out of whack.
So the common solution is for the auto parts store to sell you a new oxygen sensor — which is not cheap — and send you off on your way. Now your oxygen sensor may indeed have been bad and needed replacing. But the error code could have come from any of a dozen of other problems.
How do you know the right solution? Back to the fever analogy, do you need surgery or an aspirin? Leave it to the pros at Camarillo Car Care Center. Give us a call and let us help you resolve your check engine light issue.
