How To Know It’s Time For A New Car

Cars don’t last forever, obviously. Sooner or later, no matter how much you love your vehicle, you’ll be forced to retire it for a newer model. Even if you have maintained it properly, changing the oil every 5,000 miles and visiting the repair shop for routine tune-ups, its days are numbered. Understandably, a lot of drivers don’t know when the pull the trigger, severing the relationship they’ve cultivated over the years. After all, there’s a level of comfort that develops after years of owning a car; handling it becomes practically intuitive.

Today, we’re going to talk about an often sore subject: getting rid of it. Specifically, I’ll explain how you can identify the telltale signs that your vehicle is nearing the end of its life.

Cost Of Repairs

During the first few years, very little goes wrong under the hood. The parts and systems typically perform flawlessly; if something unexpected does happen, the warranty will likely cover it. So, there’s no out-of-pocket expense even if a component fails. However, after six or seven years, it’s not uncommon for the normal wear and tear to begin taking a toll. Your alternator might fail; you might develop a short in the electrical system; or, the transmission may start skipping.

In most cases, the parts won’t be covered by the warranty after that much time has passed. Any repairs or replacement parts will cost you a few dollars (and often, a few hundred). Over time, you’ll find that the systems are failing more frequently, requiring additional trips to the garage. When that happens, it may be time to retire your vehicle.

Is It Safe?

Cars, trucks, and SUVs are built to comply with strict safety standards. When they come off the factory floor, they’re designed to protect drivers and passengers from injury. That said, the systems that are responsible for keeping you safe can malfunction during your vehicle’s twilight years. For example, the airbags might fail to deploy during a collision. Or, your car may develop a short in the electrical system, effecting an important component.

Sometimes, a mechanic can repair the problem cost-effectively. But, as vehicles age, these issues happen more frequently. It may make sense to consider buying a newer model.

The Curse Of Aging Car Parts

Unless you own a high-performance vehicle, you’re probably not budgeting for constant repairs and replacement auto parts. Unfortunately, the older a vehicle gets, the more often these things become necessary. If you’re spending more time with your mechanic than you are with your family, it may be time to put your car out to pasture. Chances are, doing so will not only save money over the long haul, but provide a safer driving experience for you and your passengers.

Ragweed rolled up into a car

This car has some rather peculiar things on its windshield.  It looks like ragweed.  If it’s not ragweed, it’s something more hideous, more horrible. And I have some bad news.  We’re not likely to ever know what it is.

The Basics Of Your Car’s Fuel Injection System

The Basics Of Your Car’s Fuel Injection System

Vehicles have gone through significant changes over the last few decades. Most of the changes have been for the better; cars are safer, more reliable, more efficient, and comfortable. One of those changes reflects how gas is delivered to the engine. Your father – and maybe your grandfather, too – drove vehicles that used carburetors. They were comparatively cheaper, easier to work on, and problems could often be resolved by popping the hood and getting your hands dirty.

Over 20 years ago, the federal government signed legislation that required vehicles to meet stricter emissions standards. That basically signaled the death knell of the carburetor. Automakers responded by eliminating them from their production lines. Today, they’ve been replaced by fuel injection systems. In this article, I’ll give you a quick overview of the parts that make up this system and how they contribute to your engine’s output.

Engine Controller

Older readers will already know that carburetors are mechanical by design. They rely on springs and rods to do their job. Fuel injection systems need to be managed by a computer, which is called the engine controller. Depending upon your driving habits and the circumstances in which you’re driving, the controller continuously monitors how much gas should be in the mixture used by your engine during combustion. As the dynamics of your environment change, the computer adjusts the mixture. Still with me? Let’s move to the sensors and injectors.

Sensors And Injectors

Long ago, computer engineers used to have a saying: “Garbage in, garbage out.” That’s also true about your car’s engine controller. It must have access to a reliable source of data. That’s the function of the sensors; they monitor the rpm level, oxygen levels, and more. Then, they send the information to the controller.

Now, remember that the controller makes adjustments to the air/gas mixture used during combustion. That’s important. The sensors of your fuel injection system note changes in the levels of gas or air, and sends the data to the controller. When the computer receives the data, it decides how much gas is necessary in the mixture for the current driving environment. Then, it directs the injectors to spray more or less (depending upon the circumstances) gas into the mix.

A Highly-Efficient System

So, which is better, electronic fuel injection (EFI) or the old-fashioned carburetor. In nearly every way possible, fuel injection is better. Because carburetors are mechanical, they lack the level of precision that an EFI can deliver. Remember, a computer is directing the entire show by receiving a constant stream of real-time data from the sensors. Then, the computer is directing the injectors to spray more or less gas. And everything happens nearly instantly.

There are people who prefer driving cars with carburetors. For most of us, however, an EFI represents far greater advantages, including increased performance and fuel efficiency.
