Understanding the Oil Change Check Engine Light

As a car owner, you’ve likely experienced the frustration of seeing your check engine light come on unexpectedly. While there are many reasons this light may illuminate, one common cause is an overdue oil change. In this article, we’ll dive into everything you need to know about the engine light, including its function, different types, and why it comes on.

The Function of the Oil Change Engine Light

The check engine light, also known as the malfunction indicator lamp (MIL), is a warning sign that your car’s onboard diagnostic system has detected a potential issue. This system monitors various components of your vehicle’s engine, transmission, and emissions systems, and alerts you when it detects a problem.

The check engine light, specifically, is designed to alert you when it’s time to change your car’s oil. This light is triggered by a timer or mileage-based algorithm that calculates when your car’s oil should be changed. When the light comes on, it’s a signal that your car is due for an oil change.

The Different Types of Check Engine Lights and Their Meanings

There are two types of check engine lights: steady and flashing. A steady check engine light means there is a non-emergency issue with your car’s engine or emissions system. It’s still important to get this issue checked out as soon as possible to prevent further damage to your car.

On the other hand, a flashing check engine light indicates a serious problem with your car’s engine that requires immediate attention. If your check engine light is flashing, it’s important to pull over safely and turn off your car. Continuing to drive with a flashing check engine light can cause significant damage to your car’s engine.

Why the Oil Change Check Engine Light Comes On

As previously mentioned, this is triggered by a timer or mileage-based algorithm that calculates when your car’s oil should be changed. Depending on your car’s make and model, this algorithm may take into account factors such as your driving style, the age of your car, and the type of oil you use.

When the algorithm determines that it’s time for an oil change, the check engine light will come on to alert you. It’s important to note that the light is not an indicator of any other engine or emissions issues, but rather a reminder to change your car’s oil.

Understanding the light is crucial for staying on top of your car’s maintenance. By knowing its function, different types, and why it comes on, you can ensure that your car stays in good condition and avoid any potentially costly engine repairs.

Common Causes of the Engine Light

If you’re like most drivers, you probably cringe when you see your car’s check engine light come on. While there are a number of reasons why the light may illuminate, one common cause is an overdue oil change. Let’s take a closer look at the most common causes :

Low oil level

One of the most common causes is a low oil level. When your engine doesn’t have enough oil, it can cause friction between the moving parts, which can lead to damage and overheating. In addition to triggering the check engine light, low oil levels can also cause your engine to run poorly, so it’s important to check your oil level regularly and top it up as needed.

Dirty or old oil

Over time, oil can become contaminated with dirt, debris, and other impurities, which can reduce its effectiveness and cause your engine to work harder. This can trigger the check engine light and lead to a host of other problems if left unchecked. To avoid this issue, it’s important to change your oil regularly and use the right type of oil for your vehicle.

Faulty oil pressure sensor

Another common cause is a faulty oil pressure sensor. This sensor is responsible for monitoring the oil pressure in your engine and sending a signal to your car’s computer if the pressure drops below a certain level. If the sensor fails or malfunctions, it can trigger the check engine light even if your oil level is fine. If you suspect a faulty oil pressure sensor, it’s important to have it checked by a professional mechanic.

Clogged oil filter

Your car’s oil filter is responsible for removing contaminants from the oil as it circulates through your engine. Over time, the filter can become clogged with debris and dirt, which can restrict the flow of oil and trigger the check engine light. To avoid this issue, it’s important to change your oil filter regularly and use a high-quality filter that is designed for your vehicle.

Oil leaks

If oil is leaking from your engine, it can cause your oil level to drop and reduce the effectiveness of your oil. In addition to triggering the check engine light, oil leaks can also cause damage to your engine if left unchecked. To avoid this issue, it’s important to have any oil leaks repaired as soon as possible.

The oil change check light can be caused by a number of different factors, but by staying on top of your car’s maintenance and addressing any issues promptly, you can help keep your engine running smoothly and avoid costly repairs down the road.

Symptoms of the Check Engine Light

It’s important to understand that the check engine light doesn’t always mean that you need an oil change, but it can be one of the reasons. If you notice the following symptoms along with the check engine light, it’s crucial to address the issue promptly.

Engine running rough: A rough idle is one of the most common symptoms of an overdue oil change. If you notice that your engine is vibrating or shaking more than usual at idle, it’s time to check your oil level and schedule an oil change if necessary.

Loss of power: Another symptom of an overdue oil change is a loss of power. Your car may struggle to accelerate or respond properly when you press the gas pedal. This can be due to a lack of lubrication caused by dirty or low oil.

Overheating: When your engine lacks proper lubrication, it can also overheat. If your temperature gauge is running high or your engine is smoking, pull over immediately and check your oil level. Continuing to drive with an overheating engine can cause serious damage to your vehicle.

Knocking or ticking noises: A lack of proper lubrication can also cause knocking or ticking noises from the engine. This is due to metal parts rubbing together without enough oil to reduce friction. If you hear these sounds, it’s essential to get your car checked out as soon as possible.

Smoke from the exhaust: If you notice smoke coming from your exhaust pipe, it can be a sign of several issues, including an overdue oil change. When oil isn’t changed regularly, it can become thick and sludgy, leading to smoke and other engine issues.

If you notice any of these symptoms along with the check engine light, it’s essential to take your car to a qualified mechanic for diagnosis and repair. Ignoring these warning signs can lead to further engine damage and costly repairs down the line. Regular oil changes are one of the easiest and most effective ways to keep your car running smoothly and avoid these issues altogether.

Checking Your Oil

Regularly checking your car’s oil level is a simple yet crucial step in preventing the oil change light from coming on. Here’s how to do it:

How to check your oil level: Start by locating the dipstick, which is typically located near the engine. Remove it and wipe it clean with a cloth. Then re-insert it and remove it again to see where the oil level falls. Your car’s owner manual will provide more specific instructions for checking the oil level, so be sure to consult it if needed.

How often to check your oil: As a general rule, it’s a good idea to check your car’s oil level once a month. However, if you frequently drive long distances or in harsh conditions, you may want to check it more often.
