Risk of Extended Oil Change Intervals

September 2nd, 2010 by cartime

Nothing in your engine workers harder than your oil. With hundreds of moving parts, and thousands of explosions every minute, it’s no wonder that engine oil needs to be changed frequently!

You’ve probably heard the old rule of thumb: Change your oil every 3,000 miles/ 5,000 kilometers or 3 months, whichever comes first. But some car manufacturers have introduced extended oil change intervals. They figure that a modern vehicle driven under the right conditions can go for 5,000 miles/8000 kilometers or more between an oil change.

The key phrase here is “under the right conditions”. If you look at your owner’s manual, you’ll see two different maintenance schedules: one for “normal” driving conditions and one for “Severe Service”. Severe service driving conditions include stop and go, short trips, towing, hauling, hot, cold, and dusty driving. That’s why at AutoNetTV we often refer you to the severe service schedule in your owners’ manual, because, for most of us Utah car owners, that’s the way we use our vehicles in everyday life.

Recently, four of the largest auto manufacturers in the world have extended engine warranty coverage for engine damage caused by oil sludge resulting from longer oil change intervals. They found that real-world conditions require more frequent oil changes than the 7,500mi/12,000 km interval they were recommending. They subsequently recommended more frequent oil change intervals and proof of timely oil changes in order to qualify for the extended warranty.

Oil sludge is the culprit. Sludge is oil that has turned to a thick, jelly-like consistency. Sludge can block passages in the engine, preventing oil from lubricating vital engine parts. Parts wear more quickly and may fail prematurely.

Sludge is caused by several factors. The first one is simply – time. The engine oil is contaminated by exhaust gas that eventually leads to sludge. That is where the recommendation to change your oil at least every three months comes from. Sludge can also come from oil that gets contaminated by water from normal condensation. A few minutes of driving at Utah freeway speeds allows the oil to heat up enough for the water to evaporate. The problem is we often run errands or take other short trips that don’t allow the engine to warm up enough for the water to evaporate. This is especially true in winter. Sludge also forms when the engine gets too hot, causing the oil to breakdown. Stop and go summer driving, towing and hauling are all prime conditions for creating harmful sludge. And every engine has hot spots that create sludge.

Given all of these factors, estimating when to change your oil is pretty complicated. A couple of manufacturers have computer programs built into their vehicles that record the number of cold starts, how many times the cylinders fire, engine temperature and other factors. From that, the computer estimates when you should change your oil and flashes a warning. But what if you do not have a vehicle with this feature? How do you know when to change your oil? We’re not sure you really can. Which is why it is better to be safe than sorry. 3,000 mi/5,000 km or three months – whichever comes first – talk with a service advisor at Certified Automotive in South Salt Lake and see if that’s a good recommendation for the way you drive.

Keeping Your ‘Old Faithful’ Auto Running

August 25th, 2010 by cartime

At Certified Automotive we’ve had a lot of people asking how they can make their vehicles last longer. These questions are actually a reflection of a trend that’s been building for several years. The median age of personal vehicles is now over nine years. And 33 percent of all vehicles on the road have over 75,000 miles on them. It looks like it’s going to keep heading in that direction for a while. With high fuel prices a lot of folks are putting off buying a new car. Thanks to AutoNetTV, we can provide you with a video answer to this question.

So let’s say you’re one of the average people in the Salt Lake area; you’ve got a nine year old car with 80,000 miles on the odometer. What can you to do make it last another year or two?

Let’s start with the premise that there’s no reason that a modern car can’t run for 200,000 miles with proper care. The engineering and manufacturing quality is there.

Of course, some parts will wear out along the way, but there’s no reason for a catastrophic meltdown if you stay on top of your recommended maintenance. The maintenance schedule in some owner’s manuals runs out at 60,000 miles or so: how do we know what to do when we’re way past that?

It is a challenge, for example: If a service is recommended every 15,000 miles for the first 60,000 miles you can just keep getting it done at least every 15,000 miles after you hit 60,000 miles. But, it gets more complicated because older engines lose some efficiency, are dirtier inside and are just more stressed. That means it’s very important to not miss any scheduled services. Skipping just one oil change, for example, leaves an opportunity for harmful sludge to build up.

So all the usual things like oil changes, transmission service, coolant service, brakes, power steering, fuel system cleaning – all that stuff need to be maintained. People responsible for fleet vehicles around Salt Lake are positively religious about scheduled maintenance. They know that money spent on maintenance saves them three ways:

  1. it saves fuel;
  2. it prevents costly repairs, an;
  3. they can postpone purchasing new vehicles.

Having the oil changed may be the most important thing. A full service oil change means that all of your other fluids get topped off so they are never low enough to cause damage. It also gives your technician a chance to spot problems in the early stages so that you can fix them before they get expensive. And it gives you a touch point with a professional along the way to remind you of things that aren’t scheduled as often – things like differential service and timing belt replacement.

If you live in the Salt Lake area and have an older vehicle, you may need to follow the severe service maintenance schedule. Check your owner’s manual and talk with your service advisor at Certified Automotive. Conditions inside an older engine, transmission and cooling system can arguably be considered severe – so shorter intervals could well be called for.

And, we would strongly encourage you to consider using high mileage formulation fluids. They’re fluids like engine oil, transmission fluid and coolant that are formulated for older engines. They have special additives to clean deposits, and to condition and restore seals and gaskets that dry out with age. Some people start using higher mileage formulations at around 50,000 miles as a preventive measure.

Of course you also want to still look marvelous in your older car. Salt and road grime wreak havoc on your paint job and can lead to body rust – so regular washing is very important. Also, a good quality waxing is recommended at least twice a year.

Make Your Vehicle Last

August 11th, 2010 by cartime

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 Utah 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 South Salt Lake 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 Certified Automotive 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.

Timing Belt Replacement in South Salt Lake

August 5th, 2010 by cartime

Today we want to talk about timing belts. They’re something that many South Salt Lake drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most Salt Lake car owners remember because it’s not well understood.

Let’s review what a timing belt does. As you know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It’s called a timing belt because the valves have to open and close at just the right time.

Now, not all Salt Lake and Murray vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. Manufacturers started using belts rather than chains to save money in the manufacturing process. So now we’re left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous depending on where you are at the time, but it causes no internal engine damage.

Interference engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it’ll cost thousands to repair the engine.

So, what are the warning signs? Unfortunately, there really aren’t any. There aren’t tell-tale sounds. In some vehicles, a technician from Certified Automotive may be able to see part of the belt for a visual inspection, but many have a cover that’s in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage it’ll cause. There’s no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your owner’s manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your Certified Automotive service advisor right away if your manufacturer requires a timing belt replacement.

Sometimes you can go quite a while without a failure, but we’ve seen them happen within a couple of oil changes of being due. It’s not worth the risk.

What does it cost to replace a timing belt in Murray or West Valley City? Well, that really depends on what kind of car you have. I can tell you that it’s usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn’t a cheap procedure, but it’s a fraction of what it could cost to repair the damage caused by a failure.

At Certified Automotive we’re all about trying to prevent costly repairs, keeping you and your passengers safe and increasing your driving enjoyment. Thanks to AutoNetTV for their great auto video tips.

Budgeting for Maintenance In South Salt Lake Utah

August 3rd, 2010 by cartime

Life’s full of surprises in South Salt Lake Utah, some of which cost money. A leaky roof, a broken tooth, or an unexpected car repair. Certified Automotive of South Salt Lake Utah and AutoNetTV have done some research on how we can budget for proper vehicle care.

Everyone in South Salt Lake Utah does our best to budget for scheduled vehicle maintenance. What’s hard is unexpected repairs. The truth is that our vehicles can stay on the road longer than ever before with proper maintenance. That’s because of improved vehicle design and manufacturing quality. But some of those same improvements also lead to higher repairs costs.

Let’s take the fuel pump. Previous generations were often stranded by the side of the road by vapor lock. This occurred when the gas vaporized between the gas tank and the fuel pump. Fuel just stopped flowing.

You had to sit and wait until the car would start again. To alleviate the problem, fuel pumps are now located inside the gas tank. This is a great solution, but when the fuel pump fails, it’s a much more expensive proposition to replace it.

Sealed wheel bearing assemblies are another example. These wheel bearings can’t be serviced – you just have to replace the entire assembly when it starts to fail. That costs several times as much as service on non-sealed bearings.

So we all benefit in South Salt Lake Utah from design improvements, but we need to plan for repairs down the road.

There’s a tool that can be found on Edmunds.com that you can use to prepare your service and repair budget.

Let’s suppose you have a 2003 Toyota Camry – a very popular car in South Salt Lake Utah. It’s now paid for and you’d like to keep it running for the next three years. You can go to Edmunds’ True Cost to Own calculator and enter your vehicle’s data. The calculator will provide estimates of what it’ll cost to service and repair your vehicle over the next five years. The estimate is based on where you live in or near South Salt Lake Utah, manufacturers’ recommendations and repair experience for your particular model.

Of course these are just estimates – there’s no way to predict what’ll actually happen to the car in your driveway, but it’s a good starting point.

The calculator also has estimates for depreciation, financing, insurance, taxes and fuel costs.

Let’s focus on maintenance and repair. This table shows that the average monthly cost of maintenance and repairs is eighty-three dollars. That may sound like a lot, but compare it to a new car payment.

Budgeting for Maintenance

So if you set aside eighty-three dollars a month, you’d go a long ways towards taking care of routine maintenance and being prepared for the unexpected repairs that arise.

Of course, you can’t predict when something will go wrong or what it’ll cost, but at least you have a reasonable target to shoot for.

Some people around South Salt Lake Utah are afraid of what can go wrong with their older car so they buy a new one. That’s fine if you really want a new car, but if you properly maintain your older vehicle, you’ll save a lot of money on new car payments and insurance. It just makes good economic sense.

Get with your South Salt Lake Utah service advisor at Certified Automotive and work out a plan for keeping your vehicle on the road.

Introduction to Diesels for South Salt Lake Utah

July 23rd, 2010 by cartime

Something you’re going to be hearing a lot about around South Salt Lake, Utah is diesel engines. We’re not talking about semi-trucks and buses – We’re talking about diesel engine cars, pick-ups and SUVs.

Most people in South Salt Lake, Utah are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import auto manufacturers offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven’t been available in South Salt Lake, Utah. But that’s about to change.

In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in South Salt Lake, Utah so we are now ready to start seeing more diesel options offered over the next few years.

Why are so many interested in diesel engines? Well first off, diesel fuel is more energy dense. There’s more power in a barrel of diesel fuel than there is in a barrel of gasoline. That means better performance with better fuel economy.

Diesel powered vehicles get about 20 percent better fuel economy. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold with diesel engines?

If you think back to the late 1970’s and early 1980’s, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels are nothing like that.

They are quiet, clean – and very powerful. They’re so refined that many people can’t even tell they’re riding in a diesel powered car. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.

Another thing that intrigues the environmentally conscious is that it’s possible to use bio-diesel as fuel. Bio-diesel is made from vegetable oil – even recycled cooking oil from restaurants. Hybrid cars have gotten everyone’s attention these days. Look to diesel-electric hybrids in years to come to make a good idea even better.

Every year, manufacturers are planning more diesel offerings. Look for diesels in domestic light trucks, SUVs and passenger cars. Import marquees have plans to bring more of their outstanding diesel engines to South Salt Lake, Utah as well.

Now you should know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it’s very important to keep your fuel system clean with a diesel.

The good news is that your local South Salt Lake, Utah service center is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.

When we tell you to look for more diesels, you won’t be looking for smoky tail pipes as a clue. You also won’t be listening for that familiar big rig rattle. And, you certainly won’t be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.

From all of us at AutoNetTV, ten four, good buddy.

Keep Your South Salt Lake Car Breathing Free: Engine Air Filter

July 16th, 2010 by cartime

This is something really amazing: For every gallon of gas your South Salt Lake car burns, it uses 12,000 gallons of air. All of that air has to be filtered to keep your engine clean.

That’s like a hundred gallons of air every block! The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly problems. Of course, your manufacturer recommends intervals for changing your air filter. But like most service intervals, where and how you drive your car affects when your filter needs to be changed.

Dusty conditions in and around South Salt Lake or polluted city driving means you’ll need to change your filter more often. Your Certified Automotive technician can check your filter for you. In fact, it’s often a routine part of an oil change.

When you think about it, a clogged air filter won’t allow as much air through as a clean filter. Your car needs this air to efficiently burn its fuel, giving you better fuel economy and performance.

Dirtier filters don’t work as well as clean ones. A filter can only hold so much, after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most cars. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.

So have your air filter checked. If it needs replacing, it doesn’t cost very much and it should easily pay for itself in better fuel economy before your next oil change.

Stop by Certified Automotive at 3361 So. West Temple, South Salt Lake, Utah 84115, and we’ll take a look at your air filter for you. Feel free to give us a call at 801-484-0121 to make an appointment.

My Dealer In South Salt Lake Closed: What Do I Do?

July 13th, 2010 by cartime

My Dealer Closed: What Do I Do? New car dealership closings are all over the news. Nearly 800 Chrysler dealerships canceled. About 1,100 GM dealers’ contracts will not be renewed after October 2010. And record numbers are just shutting down because they aren’t selling enough cars and trucks to stay in business.

It’s estimated that some 40,000 dealership service bays could be taken out of service in the next year or so.

Of course, this is a tragedy for those who work at our local South Salt Lake dealerships and the owners that risk losing much of their life’s work. Our South Salt Lake communities will lose some of our best corporate citizens.

TPMS: Tire Pressure Monitoring For Your South Salt Lake Auto

July 2nd, 2010 by cartime

You may know that all 2008 model year and newer cars, mini-vans and light trucks in South Salt Lake come with a tire pressure monitoring system. Many slightly older vehicles around South Salt Lake 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 South Salt Lake. 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 South Salt Lake with properly inflated tires.

Local South Salt Lake 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 Utah, 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 (Certified Automotive) 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. Certified Automotive 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.

Contact Certified Automotive for more information about Tire Pressure Management Systems.
