If your dashboard is flashing a warning that says “engine oil change soon,” don’t ignore it. Engine oil is essential for keeping your car’s engine running smoothly, lubricating moving parts, reducing friction, and preventing wear.
Neglecting an oil change could lead to significant damage and costly repairs down the line. Let’s dive into why changing your oil on time is one of the most important aspects of car maintenance.
Engine Oil Change Soon
When your car displays the message “engine oil change soon,” it’s a warning from the vehicle’s onboard system that your engine oil is nearing the end of its service life. This message is typically based on your vehicle’s mileage, driving conditions, or time since the last oil change.
The oil’s ability to lubricate and protect the engine may be diminishing, and continuing to drive without addressing it could lead to engine damage.
What Does Engine Oil Do?
Engine oil serves several functions, each of which is vital for your vehicle’s performance. First, it lubricates the engine’s components, allowing metal parts to move against each other without overheating or wearing down.
It also helps with cooling, as oil absorbs heat generated by the engine and dissipates it safely. Additionally, engine oil cleans the engine by picking up dirt, debris, and microscopic metal shavings that would otherwise damage components. Fresh oil also creates a seal between the pistons, rings, and cylinder walls, improving engine efficiency.

Signs It’s Time for an Oil Change
- Dirty or dark oil: Fresh engine oil is usually a light amber color. As it does its job of picking up dirt and contaminants, it turns darker. Checking the dipstick can give you a clear visual indication of whether your oil needs replacing.
- Engine noise: Oil helps reduce friction between parts. If it becomes too old or contaminated, it loses its ability to lubricate properly. You might start to hear a knocking or rumbling sound from the engine.
- Oil smell inside the car: If you start to smell oil while driving, it could mean there’s a leak, and you should address it immediately.
- Excessive exhaust smoke: Blue or gray smoke coming from the exhaust is a sign that the oil is burning inside the engine, which indicates a significant issue that likely stems from neglected oil changes.
- Dashboard warning light: Finally, if your car’s oil light comes on, it’s a clear sign that the oil level is too low or that the oil is no longer effective at protecting the engine. This warning should not be ignored.

How Often Should You Change Engine Oil?
There used to be a rule of thumb that said you should change your oil every 3,000 miles. While that may still be true for older vehicles, modern engines, and synthetic oils have improved to the point where most cars can go much longer between oil changes—sometimes up to 7,500 or even 10,000 miles.
To find the best interval for your car, consult your vehicle’s owner’s manual. Factors such as driving conditions and habits can also affect how often you need to change the oil.
For instance, if you regularly drive in stop-and-go traffic, tow heavy loads, or operate in extreme temperatures, you might need to change your oil more frequently than someone who primarily drives on the highway in mild weather.

Consequences of Skipping Oil Changes
The longer you go without an oil change, the more likely you are to encounter problems that could lead to engine failure. Here are some of the most serious consequences of neglecting to change your engine oil:
- Increased wear and tear: As oil ages, it loses its lubricating properties. This causes increased friction between engine components, leading to premature wear. Eventually, these parts will degrade, requiring expensive repairs.
- Engine overheating: One of oil’s primary functions is to absorb heat from the engine. As it becomes dirty and less effective, it can no longer remove heat properly, causing the engine to overheat. Overheating can lead to major damage, including a warped cylinder head or cracked engine block.
- Poor fuel economy: Dirty or low-quality oil can increase resistance in the engine, forcing it to work harder. This results in a reduction in fuel efficiency, meaning you’ll be paying more at the pump.
- Sludge buildup: Over time, old oil can thicken into a sludge-like consistency, clogging the oil passages and restricting its flow through the engine. This can cause oil starvation, where critical engine components don’t receive the oil they need to function.
- Complete engine failure: Ignoring oil changes for too long can cause irreparable engine damage. At some point, the engine may seize entirely, which could require a full engine replacement. In this scenario, the cost of not changing your oil will far outweigh the expense of regular maintenance.

How to Change Your Oil
Changing your engine oil isn’t particularly difficult if you have the right tools and some basic knowledge. Here’s a quick guide to help you do it yourself:
- Gather materials: You’ll need fresh engine oil, a new oil filter, an oil filter wrench, a drain pan, and a funnel.
- Warm up the engine: Run the car for a few minutes to get the oil warm. Warm oil drains more easily.
- Drain the old oil: Place the drain pan under the oil drain plug, unscrew the plug, and let the oil flow into the pan. Be careful—the oil will be hot.
- Replace the filter: Unscrew the old oil filter with the wrench and replace it with a new one. Make sure to lubricate the new filter’s rubber gasket with a bit of fresh oil before installing.
- Add fresh oil: Once the oil has fully drained, screw the drain plug back in and refill the engine with fresh oil using a funnel.
- Check the level: After adding the oil, check the level with the dipstick to ensure it’s within the recommended range.

FAQ
Can I Still Drive with “Change Oil Soon” Warning?
You can still drive your car for a short period with the “change oil soon” message, but it’s important not to delay the oil change for too long. The warning is there to remind you that it’s time for maintenance, and the sooner you act, the better it is for your engine’s health.
Delaying it too long can reduce the oil’s effectiveness, causing increased wear on engine components. Aim to schedule the oil change within a few days or a week after seeing the message.
Can I Drive My Car with the Oil Warning Light On?
No, you should not drive your car with the oil warning light on. Unlike the “change oil soon” message, the oil warning light usually indicates a more urgent issue, such as low oil pressure or insufficient oil in the system. Driving with this light on could lead to immediate and severe engine damage, including engine failure.
If this light comes on, stop the car as soon as possible, check the oil level, and add oil if necessary. If the light remains on after adding oil, have the vehicle towed to a mechanic for inspection.
How Long Can You Drive When an Oil Change Is Due?
Once your car is due for an oil change, it’s best to get it done as soon as possible. While you can likely drive for a few hundred miles beyond the recommended interval without causing major harm, it increases the risk of engine wear and damage.
Waiting too long can reduce your engine’s performance and fuel efficiency and may lead to sludge buildup in the engine. For optimal maintenance, aim to change the oil within the next 500 miles after the warning appears, or earlier if you’re driving under harsh conditions like extreme temperatures or frequent stop-and-go traffic.
