Since driving requirements and lifestyles differ among Mission Viejo 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:

Are most of your trips less than four miles?
Are most of your trips less than 10 miles in below-zero California temps?
Are most of your trips off-highway?
Do you drive often in dusty areas?
Do you regularly tow a trailer or carry heavy loads around Mission Viejo?
Do you drive in very hot or very cold California weather?

Think about your typical week. Do you live by your nearest Mission Viejo highway on-ramp and enjoy a non-stop commute to Irvine or Lake Forest? Or, do you drive the neighborhood car pool in stop-and-go traffic on surface streets?

Let’s 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 Mission Viejo weather and road conditions to determine which end of the spectrum you’re closer to.

Why should Mission Viejo motorists care about this? Normal condensation causes moisture accumulation in the engine oil. Short trips around Mission Viejo 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 California motorists 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 pleasant California 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 fuel economy. If you want some expert advice, talk with your friendly Accurate Auto Repair advisor. We can help you restore your sedan to good working order and help you know the best schedule to follow.

Hello Mission Viejo, let’s talk about brakes. Braking, as all California car owners know, is slowing or stopping your vehicle. As you can imagine, brakes are engineered to work well on a particular vehicle application. For example, you would expect more powerful brakes on a heavy-duty pickup that routinely hauls big loads and pulls trailers, than you would on a compact car. And a Corvette that can go over 180 miles per hour would have much different braking needs than the family mini-van you drive around between Mission Viejo, Irvine and Rancho Santa Margarita.

But the mechanical aspects of the brakes themselves are just one issue. There’s also the power brake pump and brake fluid. And then there are the tires, which are critical to the effectiveness of the brakes.

Let’s step back. A new sedan or truck rolls off a local Mission Viejo showroom floor. It has brand new brakes with brand new brake pads. The brake lines and pump are filled with fresh fluid and are completely clean inside. And the tires are brand new, with full tread. It is ready to go.

Naturally, braking power is at its peak performance. Now the miles start to add up on the sedan. Mission Viejo car owners tend to focus on the brake pads. In the automotive business, the pads, and shoes on drum brakes, are called the friction material. That’s because they provide the friction used to stop the vehicle. The pads are designed to be effective throughout their useful life – it’s not until they are worn so thin as to be out of auto makers’ specs that they lose their ability to stop.

The mechanical parts of the brakes have pistons and springs that get quite a workout while breaking. Over many miles around California, these wear and get gummed up. They start to lose effectiveness gradually and could even fail – a scary possibility That’s why a regular brake inspection at Accurate Auto Repair is important for your sedan and your family’s safety. At Accurate Auto Repair we can test the operation of the brakes and see if any parts need cleaning or replacing.

That leads us to brake fluid service at Accurate Auto Repair. Some of the critical additives in the fluid that lubricate and clean the sedan fluid system are depleted over time. That and moisture building up in the system reduce the performance of the brake fluid. A brake service at Accurate Auto Repair cleans out deposits, water and dirt. Then the system is filled up with fresh fluid.

The tires are what connect the sedan to the road. Stopping force all comes down to traction. The better the tires grip the road, the quicker you’ll stop.

This is especially important on wet Irvine area highways and surface streets. Studies have shown that wet stopping distance increases significantly as tires wear down. California car owners need to understand that they can have brakes that are operating at peak efficiency and yet still be in danger because their tires are worn out.

It’s important for Mission Viejo car owners to know battery basics. First, let’s talk about which is harder on a battery – hot or cold California weather. Most Irvine car owners think it’s cold weather because that’s when we call on our batteries to have enough power to start a cold sedan engine.

However, heat does more damage to a battery than cold. Truth is, our batteries start to die a little from day one. Keeping a full charge slows the process, which is hard with short Mission Viejo trips because the alternator doesn’t have time to fully recharge the battery from starting the engine. Mission Viejo car owners can top off the charge with a computer controlled battery charger – say, once a month in the summer and every three months during the winter.

As far as how long a battery will last, statistics show that 70% have given up the ghost within four years. By that time, they aren’t capable of taking a full charge like they used to, and your sedan alternator has to work overtime to keep up. This causes your alternator to wear out early.

If you’re pushing 4 to 5 years on your battery, see your friendly Accurate Auto Repair service specialist for a battery test to see if it’s recommended to replace it. Not only can you avoid getting stranded with a dead battery, but you’ll save unnecessary wear and tear on your sedan alternator.

Some of us just love tires. All those little rubber hairs on new tires and the smell is wonderful. We live in a great time for tires. No matter how you drive, where you want to go or the look you’re after; there is a tire for you.

The same is true about wheels. The hardest part is choosing from the thousands of wheels available.

We may not be able to help with that, but we can help you get some things in mind before you consult with your Mission Viejo tire professional. Let’s start with function and think about how you drive.

For example, maybe you have a large SUV but you don’t drive off-road, so an off-road tread isn’t important. Also, because you are not out bouncing over rocks in the California backcountry, you don’t need a high profile tire to protect your rims. So that means you can probably go with the low-wide look.

If you have a winter season with rain and snow or if you find you need better ice and snow performance, they make great, high-performance snow tires that won’t make it look like you are driving a tractor.

There really are a lot of options for any given vehicle. You will find it very helpful to have a discussion like this with your Irvine tire pro when you need new tires. You can find the best solutions for your driving needs and to make improvements in ride or handling.

Picking a wheel that is the same size as what you are now running is pretty simple. But, it gets trickier if you want to upsize. Just get some help when you go bigger. All that tire and wheel still needs to fit in the available space. You do not want your tires to rub when you turn or hit a bump. You also need to make sure your brakes and suspension bits will fit with your wheel of choice. It doesn’t matter how great your car looks if it’s not drivable.

Taller, wider wheels and tires probably weigh more than your stock shoes. And it’s “unsprung” weight – that has a big impact on brake performance. The upsized shoes increase rotational inertia – if you go too big you may need to upgrade your brakes to compensate.

Another possible problem is an inaccurate speedometer. This happens because the number of rotations can change with the new wheels. Fortunately, speedometers and odometers are all controlled by the engine computer; so it is simple to get it reprogrammed and compensate for the bigger tires.

No matter what you are after: low cost, long life, high performance, traction or stunning good looks, your wheel and tire professional at Accurate Auto Repair in Mission Viejo, California can help you identify your needs and give you a custom fit. With all the options available, you don’t have to compromise. There is a tire out there with your name on it!

Virtually all vehicles come with power steering so many Mission Viejo motorists have never driven a car or truck without it. Power steering assists you when you turn your sedan steering wheel. Without it, it would be very hard to steer.

Now this power assist comes in a couple of forms. In recent years, a lot of Irvine vehicles have an electric motor that reduces steering effort and helps improve fuel economy.

The other kind of power steering is hydraulic. This is the kind most older California vehicles, and a lot of newer ones, have. Power steering fluid is pressurized by a pump and is used to assist steering. Of course, Irvine motorists need the right amount of fluid in the system. If it’s too low your steering is affected and you could damage your sedan pump.

Also, power steering fluid can become corrosive over time and damage the pump, hoses and connectors; leading to leaks and repairs. Power steering service at Accurate Auto Repair in Mission Viejo includes removing the contaminated fluid and replacing it with fresh fluid.

A word about power steering pumps: Some are powered by an electric motor. Others are driven by the serpentine belt. A worn serpentine belt stresses all of the sedan components it drives, including the power steering pump, so replace the belt at Accurate Auto Repair as advised to avoid undue repairs.

Losing your power steering while driving in Mission Viejo can be unsettling – just remember that you can still steer, it’ll just be harder. Check with your friendly Accurate Auto Repair service professional to see if it’s time to service your sedan power steering system.

In addition to power steering service, at Accurate Auto Repair we offer comprehensive automotive services including smog test and repair, factory scheduled maintenance and computerized diagnostics.

Today, we are talking about your PCV valve. The PCV Valve is a little, inexpensive part that does a big job for Mission Viejo drivers. PCV stands for Positive Crankcase Ventilation.

The crankcase is the bottom area of the engine that holds the oil. When the sedan engine’s running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause sedan engine corrosion, something we see occasionally at Accurate Auto Repair. At high speeds on Mission Viejo freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, auto manufacturers simply installed a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the sedan’s engine.

This is much better for air quality and improves fuel economy also. (Budget-conscious Mission Viejo drivers take note!) The little valve that performs this important function is the PCV valve. The PCV valve lets gases out of the engine, but won’t let anything back in. Over time, the vented gases will gum up the PCV valve and it won’t work well. That can lead to all of the problems I’ve already described, oil leaks, excessive oil consumption and decreased fuel economy.

Fortunately, it’s very easy to test the PCV Valve at Accurate Auto Repair in Mission Viejo and quick and inexpensive to replace. Even so, it’s often overlooked because many Mission Viejo drivers don’t know about it. Check your sedan owner’s manual or ask your Accurate Auto Repair service advisor. If this is the first time you’ve heard of a PCV valve, you might be in line for a replacement.

There’s another aspect to the PCV system. In order for the valve to work correctly, it needs a little clean air to come in. This is done through a breather tube that gets some filtered air from the engine air filter. Now some vehicles have a small separate air filter for the breather tube called the breather element. That’ll need to be replaced at Accurate Auto Repair when it gets dirty.

Please ask your friendly Mission Viejo service advisor about your PCV valve. For the price of a couple of burger combo meals in Mission Viejo, you can avoid some very pricey engine repairs.

You may know that all 2008 model year and newer cars, mini-vans and light trucks in Mission Viejo come with a tire pressure monitoring system. Many slightly older vehicles around Mission Viejo have these systems as well. A tire pressure monitoring system – called TPMS – consists of sensors on each wheel that measure tire pressure.

If tire pressure drops 25 percent below the manufacturer’s recommended pressure, the sensor sends a signal to a monitoring unit that causes a warning to light up on the dashboard. When you see the warning light, you know it’s time to put some air in your tires.

There are many benefits to driving with properly inflated tires around Mission Viejo. First is cost savings. Running at the correct air pressure improves fuel economy. Driving on under-inflated tires is like driving through sand – it drags down your fuel economy. You’ll also see longer, more even tread wear so your tires’ll last longer.

Another important benefit of properly inflated tires is increased safety. Under-inflated tires become hotter and that heat can actually lead to tire failure – possibly resulting in an accident. Your car and the tires themselves will just perform better and more safely around Mission Viejo with properly inflated tires.

Local Mission Viejo consumer groups, law-makers and vehicle manufacturers advocate TPMS systems hoping that they will save lives, property damage and inconvenience. While you can’t put a value on saving a life, we keep in mind that TPMS systems will carry a cost.

The systems themselves are added into the price of the car. The batteries in the sensors will have to be replaced from time to time. Parts will break and need to be replaced. In colder climates around California, ice and salt are frequent causes of failure.

In addition, there are other behind-the-scenes costs to be aware of. Every time a tire is replaced, repaired, rotated or balanced, the tire technician has to deal with the TPMS system.

Your service center (Accurate Auto Repair) must purchase equipment used to scan and reactivate the TPMS system after every tire service. Because older tire change equipment can damage TPMS sensors, your service center may need to buy expensive, new tire changers.

Since there is no uniformity among manufacturers, technicians need to be trained on several TPMS systems. These behind-the-scenes costs are very real to your service center.

That’s why they are anxious for you to understand the financial impact of TPMS systems. In the past, they’ve been able to quickly and cheaply provide tire services, and then pass the low cost on to you as an expression of their good will. But now even these simple jobs will take much longer.

Sensors will need to be removed and reinstalled. Even a tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system will need to be reprogrammed.

So when you start so see the cost of tire changes, flat repairs and rotations going up, please keep in mind that it’s because of this new safety equipment. Accurate Auto Repair just wants to keep you safely on the road – and we’re committed to do so at a fair price.

It’s important to remember that the TPMS warning only comes on when a tire is severely under-inflated. You’ll still want to check your tire pressure on a regular basis. At every fill-up is best, but you should check pressure at least once a month. Here’s wishing you safe travels.

We live in such a disposable society. It’s amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days people were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough – they had to do without. Most people couldn’t afford new cars very often, so they had to make them last as long as they could.

It’s a good thing that cars are more reliable these days. They just don’t break down as often. And the good news for us California penny pinchers is that a modern car can easily go 200,000 miles/320,000 km with proper care. The engineering and the manufacturing quality is tremendous. The missing ingredient is us Mission Viejo car owners making sure we follow the manufacturer’s recommended maintenance schedules.

Every time you go a couple thousand extra miles between an oil change, you have created an opportunity for sludge to be formed and clog passages. Then some parts don’t get properly lubricated and they start to wear out faster. Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. Same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.

It is probably even more important for older vehicles. Those engines and other systems have had more time to get dirty, so they are a bit more stressed anyway. But it is never too late to get back on track with your maintenance and to hold off further damage.

And it really does start with the oil change. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. It’s like your safety net. Go in for an oil change on time, and let your service advisor help you keep track of the rest.

Some things are going to wear out along the way, things like alternators, water pumps, etc. But fixing those at Accurate Auto Repair is cheaper than a new car payment. And taking care of problems early means they have less time to mess with other things. It is like having high cholesterol – you don’t want to wait for a heart attack before you address it.

Everyone in Mission Viejo California has blind spots – and no, I’m not talking about the fact that you really don’t sing like Jessica Simpson. I mean the areas of the road that you can’t see when you’re driving around Mission Viejo.

First let’s talk about our own blinds spots, and then we can talk about others…

To begin, we can greatly reduce our blind spots by properly adjusting our mirrors to give the widest coverage possible. Make the adjustments in your sedan before you start to drive.

First, adjust your rear view mirror to give the best possible view directly to the rear of your car. You don’t need it to get a better view of either side of the car, the kids in the back seat or your dazzling smile. The rear view mirror should look to the rear.

Next, lean your head until it almost touches the driver’s side window. Adjust your side mirror so that you can just barely see the side of your car.

Now, lean your head to the middle of the car and adjust the outside mirror so that you can barely see the right side of the car.

With your mirrors adjusted this way, you’ll have maximum coverage. Of course driving is a dynamic process – things change every second. So it’s wise to take a quick look to the side when passing to make sure that another vehicle hasn’t moved into an area you couldn’t see in your mirrors.

Depending on the kind of vehicle you drive (sedan?), you may still have some blind spots. All vehicles have an area behind them that’s blind when backing up. The bigger the vehicle, the bigger the blind spot. A pick up or SUV can hide a small child – an RV, bus or tractor-trailer can hide an entire vehicle. So be careful around our Mission Viejo streets!

As you drive around the Irvine area, avoid staying in other diver’s blind spots. You can’t count on them to be watching their mirrors and looking out for you.

Let’s talk about safely sharing the road with heavy trucks and buses. In crashes involving a truck and car, the car causes about 40 percent of the accidents. But 78 percent of the fatalities are with the car. The laws of physics are against the smaller vehicle, so it pays to take extra precautions around trucks and buses.

Heavy vehicles have huge blind spots: to the rear, on both sides and up front. They also can’t maneuver like a car. They take twice as long to stop and need twice as much space as you do in your sedan or other type of car. You need to keep wide margins when driving around one of these big rigs.

Here are some tips for passing a heavy vehicle in the Irvine area:

• Avoid the blind spots. If you can’t see the driver’s face in one of his mirrors or in a window, he cannot see you!
• Don’t follow too close. If you can’t see one of the truck’s mirrors, you’re too close.
• Make sure there is plenty of room to pass. Trucks are long and take time to get around. If you’re on one of our local Mission Viejo California two way highways, wait for a passing zone.
• Don’t linger when passing. Because the blind spots are so big on the sides, you want to get through them quickly. If you can’t pass quickly, drop back.
• Pass on the left whenever possible. A trucks’ blind spot is much larger on the right.
• Be attentive and wear your seat belts while driving anywhere around Mission Viejo, even short drives.
• Don’t be aggressive when driving around trucks. Because of their size, they appear to be going slower than they really are. Cutting it short around a truck could be disastrous.
• Use your turn signals when starting to pass. Once you can see the full truck in your rear view mirror, it’s safe to signal and move over. Don’t cut it short or slow quickly when you pull in front of a truck.
• Be careful passing a truck at an intersection. Trucks need to turn wide to maneuver through city streets. Squeezing between a truck and the curb could put your car in the Mission Viejo body shop. Look for the truck’s turn signals.

We at Accurate Auto Repair want you to watch those blind spots – but feel free to sing in the shower all you want.

Today in the Accurate Auto Repair auto care blog, we’re going to talk about oil change intervals. It seems that as engine technology advances, recommended oil change intervals have gotten longer for Accurate Auto Repair customers. High quality oil in a well-engineered sedan engine has lead to extended intervals. But it’s also lead to some confusion among Mission Viejo drivers.

The old mantra “change your oil every three months or three thousand miles, whichever comes first” once applied to every vehicle on Mission Viejo highways. Time and miles take their toll on motor oil. But now, you could have a different oil change recommendation for every car or truck you own.

Mission Viejo drivers are like everybody else, they have a tendency to follow the oil change schedule of the vehicle with the longest interval. Of course, that can lead to problems. For example, recently four of the world’s largest auto makers shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles.

In real world Mission Viejo driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance. Quite literally petroleum jelly – like Vaseline. This goop was clogging sedan small engine passages so the oil wouldn’t flow to some parts of the engine. This resulted in engine damage. We see it too often at Accurate Auto Repair in Mission Viejo.

The auto makers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner had to follow a new, lower service interval, and provide proof of oil changes in order to make a warranty claim.

So here’s the bottom line: with longer oil change intervals, it’s essential to follow them closely. Back in the day of 3 months or 3,000 miles, if you went an extra month or an extra thousand miles, your oil was still fresh enough that it didn’t have time to build up much sludge.

But if your recommended interval is 6,500 miles and you go over another thousand, you’re getting into heavy sludge territory. You absolutely need to follow mileage intervals very closely. And don’t forget your severe service schedule. If you do a lot of stop and go driving in California, short trips, drive in dusty or polluted Mission Viejo conditions, hot or cold weather, or haul heavy loads, you’re driving in severe service conditions. Your Accurate Auto Repair advisor can help you determine which schedule to follow.

So check your sedan owner’s manual or talk with your Accurate Auto Repair service advisor about where and how you drive in Mission Viejo. Should you change your oil closer to the regular schedule, or the severe service schedule? You need to make the call.

Let me give you an example of this. Some newer sedans have an oil change indicator. It has a sophisticated computer algorithm that tracks number of cold starts, engine temperature, RPMs, mileage, and many more variables to come up with a recommendation for when to change the oil.

Depending on driving conditions, the indicator in one test vehicle came on at anywhere from 2,500 miles to almost 7,000 miles. It’s typically just over 4,000 miles. Clearer sometimes, we’re driving easy miles that are easy on the sedan – like a long road trip. Sometimes, we’re driving hard California miles – like towing a heavy trailer or a lot of around town driving. But, usually, it’s a combination of both.

Once again, it’s up to you to make the call as to when to change your oil at Accurate Auto Repair to protect your sedan engine. Another place where California drivers can go wrong is with the type of oil they use. More and more new cars are coming to Mission Viejo owners filled with synthetic oil. Without going into a lot of detail right now, let’s just say that synthetic oil lasts longer and is very resistant to oil sludge.

But it also costs quite a bit more, so some Mission Viejo people are tempted to use conventional oil for their oil changes. Now, it’s always best to use the oil recommended by your manufacturer. Check your owner’s manual see if a conventional oil alternative is allowed.

But getting back to the problem, if your sedan came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil. If you use conventional oil, you can’t use the synthetic interval. You need to shorten it.
