Ethics of Automotive Repair in TUCSON



We're going to be talking about the ethics of automotive repair. It seems like news outlets really like hit-and-run reporting; they hit everyone from groceries stores to retail to physicians. And the TUCSON automotive service and repair industry hasn't been given a pass either.

Unfortunately, every profession in TUCSON has some bad actors that hurt the reputation of everyone else. On the automotive side, industry associations and professional licensing organizations are very committed to high ethical standards.

Yet some people remain uncomfortable with TUCSON automotive service and repair. It may start with the fact that our vehicles are a big investment and we rely on them for so much in our lives. That alone guarantees our attention. And how well we understand the recommendations really impacts our comfort level.

If we understand what's recommended and the benefits of taking care of the work – and the pitfalls of putting it off – we'll have more trust in the recommendation. So communication is key. It's like going to the doctor; If she's using medical jargon and takes a lot of basic medical knowledge for granted, we have a hard time following her train of thought. It can be like that with your TUCSON service advisor too. He's so familiar with all things automotive, he may forget you don't know a PCV from an EGT.

If you don't understand what your doctor's talking about: ask some questions. If you don't understand what your TUCSON automotive advisor's talking about: ask some questions.

Let's go back to those ethical standards; when we hear a repair recommendation, we always ask ourselves, "Is this really necessary?" Well, here's the industry standard:

If a technician tells you that a repair or replacement is required it must meet the following criteria:

  1. The part no longer performs its intended purpose
  2. The part does not meet a design specification
  3. The part is missing

For example, it you take your car in for a grinding noise when you step on the brakes, you may just think you need new brake pads. After the inspection, the technician at All Makes & Models Auto Repair says that you have a cracked rotor and need to replace it.

If you tried to get him to simply put new pads on, he would say that if you didn't want to replace the rotor; All Makes & Models Auto Repair would ethically have to refuse the repair.

To just put pads on a cracked rotor would have been very wrong. The brakes could've failed at anytime and needed to be repaired – not just have a band-aid slapped on them.

Now, looking at something not so serious, the technician may suggest repair or replacement if:

  1. The part is close to the end of its useful life – just above discard specifications or likely to fail soon
  2. To address a customer need or request – like for better ride or increased performance
  3. To comply with maintenance recommended by the vehicle's manufacturer
  4. Based on the technician's informed experience

Of course, the technician has the burden of making ethical recommendations and properly educating their customers. For the customer, if you are uncomfortable with a recommendation, ask some questions. More information is always a good thing.

Direct Fuel Injection Update from All Makes & Models Auto Repair

For those of you in TUCSON, AZ who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.

For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.

So what are the differences from a conventional engine?

The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.

With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.

First, the fuel is squirted in at hundreds of times more pressure, so it's atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.

Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can't do its job as well. That means less power and worse fuel economy for your vehicle and can lead to damaged fuel injectors.

Replacing fuel injectors at All Makes & Models Auto Repair isn't cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we're talking mortgage payment-range to replace a set of diesel injectors.

A professional fuel system cleaning from All Makes & Models Auto Repair gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they'll last a long, long time.

All Lined Up: Wheel Alignment Service at All Makes & Models Auto Repair

When all of your vehicle's wheels are lined up exactly with each other, your wheels are in alignment. Hitting a road hazard or even just the normal bumps and bounces of everyday driving in TUCSON can cause your vehicle's wheels to be out of alignment.

Driving for an extended time around TUCSON when your wheels are out of alignment results in uneven tire wear. This is dangerous … and expensive. Worst case scenario, you have a blowout on a crowded AZ highway. It can also cause premature wear to your suspension system, which can be really expensive to repair. At the very least, you may have to replace your tires years too early.

The ideal alignment for your vehicle was designed by its engineers. Alignment service at All Makes & Models Auto Repair starts with an inspection of the steering and suspension – to see if anything's bent or broken. Then your friendly and knowledgeable All Makes & Models Auto Repair technician will look at tire condition.

From there, the vehicle is put on an alignment rack and an initial alignment reading is taken. The wheels are then aligned to vehicle’s specifications.

Your vehicle owner's manual probably has a recommendation for how often your alignment should be checked – usually every couple of years. If you suspect an alignment problem, get it checked at All Makes & Models Auto Repair before you suffer expensive tire or suspension damage.

A Stitch in Time at All Makes & Models Auto Repair

You probably have heard that expression, "A stitch in time saves nine." In other words, if you fix an issue at its early stages, it will prevent a much more difficult problem later. That's certainly the case with your vehicle, and here's a true story to demonstrate it.

A driver noticed his vehicle was due for an oil change, so he took it in to his service facility early in the morning so he could wait while the work was performed. The technician routinely checks the battery on vehicles just before extreme weather is approaching (cold or hot), so with winter coming up, he hooked up the load tester (it measures voltage while a load is put on the battery). It showed the battery wasn't holding a charge well.

The technician checked the manufacturing date on the battery, too (most batteries have a date stamped in code somewhere on them). The date showed it was five years old. While batteries can last more than five years, many technicians say you should expect to get anywhere from three to six years out of them, depending on what they go through.

So, this battery was getting a little long in the tooth, and it wasn't holding a charge particularly well. But how much current was it being sent by the vehicle's alternator? If it wasn't getting enough, that might be a factor. A test of the charging system showed the alternator was putting out the correct amount of power. The technician recommended replacing the battery, and the driver agreed.

That was the stitch in time. Had the technician not checked the battery, that driver likely would have been stranded the next time he tried to start his vehicle on a very cold day. What originally was supposed to be just an oil change led to a technician's sharp diagnosis and a little preventative maintenance for one fortunate driver. Sometimes timing is everything.

Check Your Shocks and Struts at All Makes & Models Auto Repair


 

Today we're talking to TUCSON drivers about shocks and struts. They're so easy for AZ folks to forget about because they last so long and wear out so slowly. But your shocks are really responsible for keeping your tires on the road – so they're very important.

Without shocks, your wheels would be bouncing over bumps and lifting on corners. The shocks push the tire down to the road to maximize traction. Good shocks equal good ride quality and safe handling for TUCSON drivers.

There's a difference between shocks and springs. Springs support the weight of the vehicle, keeping it suspended up off the axles. The shocks moderate the rebound motion as wheels hit bumps. Now a strut combines a shock and a coil spring in one compact unit.

It's best to replace all four shocks at the same time. That way you'll have even, predictable handling at all four corners. Anything less could be dangerous.

Visit All Makes & Models Auto Repair to have your shocks and struts inspected by a professional.

What's up with Diesels in TUCSON?

Would you be surprised to learn that about half of the passenger cars in Europe have diesel engines? You might also be surprised to learn that most manufacturers produce a variety of diesel-fueled cars for purchase abroad.

Diesel-fueled vehicles haven't been as popular in the North American markets like AZ. But that won't be true for long. North Americans are seeing a lot more diesel-fueled vehicles on the road. And we're not talking about buses and trucks. These vehicles will be passenger cars, pick-ups and SUV's.

There are two reasons for this. The first is a recent change in environmental laws that have upgraded emissions standards for diesel fuel in North America. Diesel fuel in North America used to have higher sulfur content than European fuel, meaning that it was a dirtier fuel to burn. That was okay for larger vehicles, but the lighter-weight engines in passenger vehicles just couldn't tolerate it.

But that high sulfur content is now a thing of the past. Fuel producers are now required to sell cleaner diesel fuel in TUCSON. That opens the North American market to more diesel-powered vehicles. The second reason we're going to see more of these vehicles in TUCSON is that they're more fuel-efficient than their gasoline-powered counterparts. Diesel fuel has higher energy density than gasoline. That translates to more power per barrel of fuel. In your tank, that translates to better engine performance and about 20% better fuel economy.

People in TUCSON may associate diesel engines with black smoke, noise and a definite “shake, rattle and roll.” That's also a thing of the past. Modern diesel engines are smooth, quiet and produce cleaner emissions than gasoline engines. Also, forget that three-second wait behind a diesel vehicle at a stoplight. Modern diesels are just as quick to accelerate as other vehicles on TUCSON roads.

Diesel engines have other advantages over gasoline engines. Diesel engines are heavier than gasoline engines because they require more heavy-duty parts, but that means the engines are more durable and can last longer than gasoline engines. Also, diesel engines may be the engines of the future since they can burn many of the new bio-fuels.

Bio-diesel can be manufactured from vegetable oils, including used cooking oil from TUCSON restaurants. Just think, one day you could fuel your vehicle on stuff that was once considered waste—one step closer to a cleaner environment here in AZ. And if you think hybrid cars are environmentally sound, consider what a diesel-electric hybrid could mean. 

TUCSON drivers who are considering buying a diesel-fueled vehicle should know that  preventive maintenance and inspection schedules are different for a diesel engine than a gasoline engine. Diesel fuel is harder on emissions systems than gasoline, so the filters and other devices have to be changed and checked more often. Also, the fuel injection system operates at much higher pressures for diesel than for gasoline, so keeping it clean becomes a higher priority.

When you switch from a gas vehicle to a diesel, you'll have to learn some new rules of vehicle care. But you won't be alone. Most TUCSON service centers are aware that diesels are coming to North America and are already prepared to provide service for diesel engines. At All Makes & Models Auto Repair, we are well-versed in diesel technology. You can rely on our team of automotive professionals to provide quality service for diesel-powered vehicles.

All Makes & Models Auto Repair Service for Your Exhaust System

Your vehicle's exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your vehicle.

The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is important American Fork residents keep their exhaust system in good repair.


The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.

The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn't require any regular maintenance, but it can wear out. If it fails, you will need a new catalytic converter to pass an emissions test in AZ. Call All Makes & Models Auto Repair at 5208077571 if you suspect a problem with your catalytic converter.

Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the vehicle engine's computer keep the fuel-to-air mixture at optimal levels.

The muffler is also part of your vehicle exhaust system, but it deals with a different kind of emission. It keeps your vehicle from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.

It is important that damaged mufflers be replaced immediately at your TUCSON automotive service center, especially if they are leaking. Not only will the extra noise annoy your TUCSON neighbors, a leaky muffler could be serious.

The entire exhaust system is attached to your vehicle by hangers and clamps. These fasteners can rust, come loose or break. The components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts such as wires and hoses. These can melt, causing serious and damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.

Caring for your vehicle exhaust system at All Makes & Models Auto Repair yields cosmetic benefits like quieting your engine sounds, but also may impact your health and safety. Your life, or the life of a loved one, may actually be on the line.

E-85 Fuel Safety Advice from All Makes & Models Auto Repair


 

Today at All Makes & Models Auto Repair we want to talk with you about a very important safety issue. This automotive safety warning is coming from a very unusual source: fire fighting experts. You've probably heard of E-85 gasoline being offered in the TUCSON area. Some newer vehicle models are specifically built to run on E-85 – the rest are not.

Does your vehicle use E-85 gasoline? Bring it down to All Makes & Models Auto Repair at 1305 E BENSON HWY in TUCSON, AZ 85714, to find out, or give us a call to make an appointment by calling 5208077571.

E-85 gasoline has been developed to fight air pollution and reduce oil consumption. E-85 fuel is a mix of 85% ethanol, a grain-base alcohol, and 15% gasoline. So-called Flex-Fuel vehicles are designed to use either normal gasoline or E-85 gas. The result is lower exhaust emissions to our local TUCSON community.

All gas engines can run with up to 10% ethanol, and in fact a lot of gasoline sold in the TUCSON, AZ, area does contain some ethanol. The problem comes when well-meaning residents without Flex Fuel certified vehicles put E-85 into the tank.

At a 15% concentration, the potential for problems arises. Because of the chemical differences between ethanol and gasoline, special seals and gaskets are needed for Flex Fuel vehicles. In a normal engine, the ethanol in E-85 gas will eat away seals and gaskets. This leads to gas and oil leaks.

You TUCSON auto owners can imagine the fire hazard caused by leaking gasoline. AZ fire fighting experts caution drivers to only use E-85 if they know their vehicle is certified to handle it. They expect vehicle fires to increase because of using the wrong fuel in non-Flex Fuel vehicles.

Buying the Right Tires and Wheels in TUCSON, AZ

Everyone in TUCSON, AZ eventually replaces their tires, whether it's because they're worn out or they're just looking for something different. There are so many great tire choices in TUCSON, it can be difficult to sort them out. Let's group the broad spectrum into several categories that will help in the selection process.

One category is often referred to as "summer tires". Summer tires are designed to be driven on the road when temperatures are generally above 45 degrees F (7 degrees C). Their tread design is optimized for traction on dry roads around AZ and they're also able to effectively displace water on rainy roads.

So if you live where its summer all year round, these tires will work well for you. If you like maximum performance in warm weather, but still live where it gets cold and snowy, you'll want to change your summer tires for winter tires as the weather starts to change.

There's a range of tires within the winter tire category. If you live where there's a lot of snow and ice, look for the mountain and snowflake icon that signifies a severe snow rating. If you have milder winters and still want a performance component, they make a winter tire for you as well.

For many people, an all-season tire is the answer. You will give up some of the performance at the extreme ends of the summer tire/ winter tire spectrum, but you will find a long wearing tire that gives both good highway performance and winter traction on our TUCSON, AZ, roads.

Within the all-season category, there are many choices that your tire advisor at All Makes & Models Auto Repair can help you evaluate.

All Makes & Models Auto Repair: Good Service and Good Fuel Economy

Most TUCSON auto owners want to save on gas and seek our advice on improving economy. At All Makes & Models Auto Repair, we are frequently asked, however, if it is really worth the extra effort. Just how much money can TUCSON drivers actually save?

In today's All Makes & Models Auto Repair article, we're focusing on the things you can do to improve your vehicle’s economy driving around AZ. We'll tell you the potential savings per gallon of gas at $3.50, and we'll show a chart that also shows the savings at $3.00 and $4.00.

 

DOLLARS PER GALLON $3.00 / $3.50 / $4.00

TUNE UP 4%.12.14.16

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best mileage. A clean air filter means you get plenty of air. The fact that the air's clean protects your engine. That can save you up to 10 percent or 35 cents a gallon.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

AIR FILTER 10%.30.35.40

Fixing a faulty oxygen sensor can improve economy by up to 40 percent. That's a whopping $1.40 in savings per gallon. Bring your car to All Makes & Models Auto Repair in TUCSON and we'll check your oxygen sensor.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

FAULTY O2 SENSOR 40%1.201.401.60


Chances are that if your oxygen sensor is kaput your Check Engine light will come on. Now, there are any number of things that could cause your Check Engine light to come on besides oxygen sensor problems. But if it's on, get it checked out as soon as you can at All Makes & Models Auto Repair.

Here's an easy one for TUCSON auto owners. Inflate your tires to the recommended pressure. That could save you three percent or 11 cents a gallon. Even a little drop in pressure will bring down your economy, so check your tires every week.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

TIRE INFLATION 3%.09.11.12

Your vehicle has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced economy, or up to seven cents a gallon.

Another thing TUCSON vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping 100 pounds of extra weight adds up to a 2% savings at the pump.

So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in AZ.
