5 Common Car Repairs You Should Not Do Yourself

Years ago, passenger cars were much simpler to repair, or maintain than they are today. This is why some drivers in decades past worked on their own vehicles. Modern automobiles, however, are extremely complex machines, requiring specialized tools, training, and experience to repair them.

While it is tempting for some car owners to try to save time and money by repairing their own vehicles, it is not advisable. People who work on cars, but are not qualified to can jeopardize not only their safety, but also the welfare of other motorists on the road.

In this blog, let’s look at 5 common car repairs that you should not do yourself.

Common Car Repairs by Mechanics

Brake Repair

A car’s brakes seem pretty simple. You press the pedal, and the vehicle stops. However, what is behind that process in modern cars is extremely complex. Brakes are made up of many individual components, all working together. These include brake pads, calipers, rotors, brake fluid, electronic sensors, motors, and a master cylinder.

With the introduction of Automated Driver Assistance Systems (ADAS), your car’s brakes are likely part of a network of computer modules, electronic sensors, motors, and software that run the Anti-Lock Braking System (ABS) Lane Departure System (LDS) or Collision Avoidance Systems. Many of these safety features require post repair calibration to operate correctly. Because a vehicle’s braking system is such a critical part of its safety features, be sure to have a qualified technician repair it.

Transmission Repair

Automobile transmissions have always been complicated, but this is especially true today. Because modern transmissions are part of the powertrain control network, classic symptoms like slipping, erratic or hard shifting are generally not transmission malfunctions but rather a sensor providing incorrect data to the powertrain control module and/or transmission control module. Discovering the root cause of these symptoms usually requires advanced specialized training.

In fact, not all mechanics are qualified to do it. If you sense your transmission is slipping, or not shifting correctly, be sure to take the car to a technician who is qualified to diagnose the problem and fix it.

Engine Diagnostics

Today’s vehicles have multiple onboard computers that help monitor and control their performance. If the Check Engine light appears on your dashboard, this is your car letting you know that something needs attention.

Well-meaning parts store employees can plug a diagnostic reader into a port under the dash and learn from a series of codes why your engine light is glowing. While some people try to interpret a code by looking it up on the internet, correctly repairing the issue is an entirely different skill set. A qualified technician will use specialized tools to analyze which sensors are reporting outside of their acceptable parameters then perform tests to discover why it is occurring. Pro Tip: The root cause is generally not the sensor which illuminated the “check engine light”.

Car Electrical Repair

Automobile electrical systems are more complicated today than any other period in the history of vehicle manufacturing. The science of electricity hasn’t changed since Ben Franklin flew his kite in a thunderstorm. But the strategies employed to control nearly every component of a modern car is changing with every model year. Even simple light bulb functionality requires knowledge of advanced electronic networks.

Be sure to take your car to an experienced, trained mechanic to address any electrical system problems.

Suspension Repair

Like your car’s braking system, its front and rear suspension play a critical role in keeping you safe.

They are designed to support the weight of the car as it travels down the road. In addition, your car’s steering is dependent upon the front suspension operating properly.

Over time, a vehicle’s suspension parts will wear, and need to be replaced. Because your safety is literally riding on your car’s suspension, be sure it is serviced by people who have been formally trained to repair, perform an alignment and calibrate any affected sensors such as SAS.

Car Starter Issues

One of the most often used components on your car’s engine is the starter. Without it, your vehicle won’t be taking you anywhere.

Starters in most modern cars are attached to the engine in hard-to-reach spots. In addition, many vehicles require that other parts be removed before the starter can be accessed. If your starter is not performing as it should, be sure to take the car to a qualified mechanic who can fix it properly.

When to Consult a Mechanic: Key Signs to Watch For

You should consult your mechanic if you experience any of these common car problems.

Grinding sounds, or poor stopping performance from the brakes.
Transmission shifting issues.
The “Check Engine” light comes on.
Something goes wrong with the electrical system.
The car begins to ride rough, or not steering like it should.
The starter will not engage the engine.

What’s the Difference Between Conventional vs. Semi-Synthetic Oil?

When it comes to the maintenance of vehicles, motor oil, and oil changes are imperative. Motor oil is essential for properly lubricating a car’s engine, at all temperatures and speeds.

There are many different types of motor oil on the market today, including conventional, synthetic, and semi-synthetic blends. No matter what kind of car you have or its age, it’s important to know the right kind of oil to use, so your vehicle can operate at top performance and provide many years of reliable service.

Different Types of Motor Oil

Let’s look at the different types of oil used in cars on the road today.

Conventional Oil

Conventional oil is a refined crude oil, and compared to other oil types, it generally has fewer additives. Conventional oil is recommended for older vehicles and those seeking the least expensive option.

Full- Synthetic Oil

Unlike conventional oil, which is made of crude oil, synthetic oil is entirely manufactured, so its formula is always the same and helps with vehicle performance. The chemical properties in fully synthetic oil have been refined, removing impurities and adding properties that will benefit fuel and engine efficiency. Synthetic oil is recommended for high-performance vehicles, and although it is more expensive, it will allow for less frequent oil changes than conventional oil.

It is important to know that not all cars can run properly on full-synthetic oil. Be sure to refer to your owner’s manual for proper guidance.

Semi-Synthetic Oil

Semi-synthetic oil, or a synthetic blend oil, combines both full synthetic oil and conventional oil. While this mixture generally has more conventional oil than synthetic oil, it does get the beneficial additives of synthetic oil that help protect the engine. This type of motor oil is less expensive than full synthetic, making it a more economical choice.

Be sure to check your car’s specifications for the right oil to use.

How To Know Which Motor Oil Is Best?

The advantage of a conventional oil is the cost. And for older vehicles, it is best and provides the best engine protection and lubrication for aging engines.

Synthetic oil is made of properties that prevent corrosion and is designed to protect today’s high tech engines. It’s more expensive than conventional oil, but is a necessity for many newer cars.

Synthetic-blend oil is a good middle of the road option, as it combines both conventional and synthetic blends together. Be sure to consult your owner’s manual about whether your car was designed to utilize a hybrid blend such as this one.

Best Type of Oil for Your Car? Synthetic Oil or Conventional Oil?

What type of oil should you use for your car?

No doubt at some point in time you may have heard the ongoing debate about which type of motor oil is best for your motor vehicle.

Functions of Motor Oil

Although the primary function of motor oils is to lubricate all the moving parts of the engine, it carries out a few other functions as well. Motor oils serve to keep the engine cool and provides protection against wear by reducing friction. It also prevents corrosion and keeps the engine free from small pieces of debris.

Conventional Motor Oil

Conventional motor oil has its origins in crude oil, which is pumped from the ground and is processed. A base oil is produced to which additives are added. This changes the properties of the liquid giving it protection properties, improved heat breakdown levels, and viscosity.

Synthetic Motor Oil

Unlike conventional motor oil the base oil of synthetic motor oil comprises artificial or synthesized components, thus its name. Like conventional motor oil however, additives are added to give it properties similar to those of conventional motor oil.

Differences Between Conventional and Synthetic Motor Oil

Although they both carry out the same functions both oils have significant differences in addition to having their pros and cons. Conventional motor oil contains minute amounts of wax, sulfur, and asphaltic material, which are by-products of its manufacturing process. Synthetic motor oil, on the other hand, because it is chemically produced, has none of these contaminants. Another difference between the two is that synthetic motor oils will flow at much lower temperatures making it preferable in harsh winter conditions. At these same low temperatures conventional motor oil would freeze. Being more consistent in size and shape, the molecules of synthetic motor oils better withstand extreme temperatures; hence it will take longer to break down under extreme heat than conventional motor oils. Synthetic motor oils have very low viscosity ratings and in some cases have been known to flow up to seven times faster than conventional motor oils. This comes in handy at engine start up time, as that is when the most engine wear is likely to occur.

Making Your Choice

In deciding on which motor oil you will be using there are other factors besides those already mentioned, which will have to be taken into account. One of these is the type of car that will be using the motor oil. A high performance racecar owner will obviously choose the synthetic motor oil, as that is the oil they were specifically made to use. Newer cars with smaller clearances will also lean towards synthetic motor oils. The cost of the motor oil will play a significant role in the decision on which oil to use too, as the cost of synthetic motor oil can be as much as four times that of conventional motor oil. If someone changes their car yearly they may say why bother towaste extra money on synthetic oil. The car’s age could also play a part as waxes and sludge build-up by conventional motor oil could mask worn engine seals. These could come to light with the introduction of synthetic motor oils, which tends to break down and clean away those build-ups, thus possibly causing leaks and creating problems.

For all of your oil change needs be sure to visit Car-X.com The debate is by no means over and the points here by no means exhaustive, but it is hoped that they will at least point you in the right direction when the time comes for you to buy motor oils

To Change My Oil or Not?

Regular oil changes will save you money in the long run! Most car manufacturers now recommend oil changes between 7,500 and 10,000 miles, although some specify 5,000-mile intervals. The type of engine oil, the age and make of your vehicle and driving habits dictate when to change engine oil. When in doubt check your vehicle’s owner’s manual. If you put off oil changes, it can lead to engine damage.

In addition to regular oil changes, it’s highly recommended that you change your oil filter frequently. The oil filter protections your engine from abrasive particles such as dirt and other solid contaminants. If you wait too long to change the filter it can become clogged, and then as a result unfiltered oil will be circulated through your engine and can cause easily prevented corrosion or damage to your engine.

To find out just how often you should change your oil filter, make sure you consult with your Car-X Man during your next oil change and free inspection!

Why Are Oil Changes Important?

Even the most inexperienced driver knows that engines have a lot of moving parts. If not properly lubricated, these moving parts begin to wear down as friction increases. A driver that does not have his oil changed on a regular basis may damage vital engine parts. In fact, the number one reason for engine failure is wear and tear that is caused by an increase in viscosity, which means the oil becomes thick and sticky, like mud. This worn-out oil clings to moving engine parts and instead of lubricating them, it destroys them.

What happens next?

If a vital engine part breaks, the vehicle will not move. It’s really that simple. Because these parts are intricate and replacing them requires a professional, it is often cheaper to simply buy a new engine or a new car. They are cheap and they only take a few minutes.

How Often?

Even the experts disagree about oil changes. Some say that you should get them every 3,000 miles, while others say every 7,000 miles is fine. Who’s right? That’s hard to say. But what we do know is that most drivers do not get their oil changed every 3,000 miles.

The average American drives about 10,000 miles each year. According to the purists, that average motorist should get his oil changed at least three times per annum. Most drivers do not follow this advice. Not because they cannot afford frequent oil changes, but because most folks don’t believe that oil is dangerous after only 3,000 miles.

The best advice we can give you is to follow the manufacturer’s recommendation. The manufacturer only benefits if he is honest. Since he wants the customer to buy more of his cars in the future, it is better for him if the customer is satisfied with his purchase. All manufactures thoroughly test their cars and trucks and they know exactly how long they can go between preventative maintenance appointments.
