Read on to learn more about how long you can go without an oil change and the oil change warning light.

If your vehicle’s oil warning light turns on, you have roughly 500 miles of driving before your car encounters issues. That’s about two weeks of driving.

If you continue to ignore it, your car will surely encounter severe mechanical damage. So, it is always recommended to seek help from a professional mechanic once the oil light turns on.

Overdue Oil Change Symptoms

You are not supposed to ignore it once your vehicle is due for an oil change. Knowing when it is due is convenient if you have a modern vehicle since the oil warning light is hard to ignore.

Most older vehicles don’t come with an oil warning light. In this case, you have to monitor your mileage or subject your vehicle to an oil change every 3 to 6 months. It’s not that hard to monitor it too.

Here are several overdue oil change symptoms you may encounter:

Service Warning Lights
Low Oil Level
Stalling Engine
Dirty or Dark Oil
Poor Fuel Economy
Dark Exhaust Smoke
Overheating Engine
Burning Oil Smell

1. Service Warning Lights

If your car’s oil warning light turns on, it needs an oil change. Again, newer car models have warning lights. So, it’s quite hard to miss this.

Other warning lights will tell you that your car has low oil pressure or overheating. But a “check engine” light is enough to tell you that your car is due for an oil change.

2. Low Oil Level

It’s fairly easy to check your vehicle’s oil manually. Take out the dipstick and wipe it clean. Then, stick it back in.

On the second check, observe the fluid level. If it seems too low, your car is most likely due to an oil change. It is also possible that you need to top off your car’s fluid. Also, observe if there is an oil leak as it could also be the reason for having a low oil level.

3. Stalling Engine

Does your car’s engine seem to seize up from time to time? Or does it stall, especially during cold weather conditions? If yes, your car might have a low engine, an oil leak, or bad oil.

In this case, it is best to have your car checked by a professional. A vehicle needs an oil change to address this issue most of the time.

4. Dirty or Dark Oil

Using your car’s dipstick, you will also be able to tell the quality of your oil. A dirty, milky, or dark oil is a sign that your car is already overdue for an oil change.

5. Poor Fuel Economy

If clean oil is not enough, it will affect the engine performance. You will surely notice a decline in fuel efficiency, which might be a sign of other problems:

Exhaust system
Engine
Fuel system

6. Dark Exhaust Smoke

Dark exhaust smoke may mean low or dirty oil that affects the engine. However, it can also mean a catalytic converter problem or an exhaust leak. Whichever it is, you should bring your car to a professional mechanic to have it checked.

7. Overheating Engine

If your vehicle is not receiving enough clean oil, it will not run efficiently. So, when your car’s engine overheats, it most likely results from an overdue oil change.

But it is possible too that the issue is with the cooling system. Again, it is recommended to have your car checked by a professional if you encounter this issue.

8. Burning Oil Smell

If you smell burning oil while driving, then it is a sign that your car needs an oil change as soon as possible.

What Happens If You Wait Too Long for an Oil Change?

how long is too long to go without an oil change

All car manufacturers highly advise car owners to regularly subject their vehicles to an oil change. Remember that oil has several functions, including:

Engine protection,
Keeps the engine clean and
Engine cooling.

Here are some car issues you will encounter if you don’t change your motor oil:

Components Will Wear Off
Dirt Will Build Up
Engine Will Overheat
Voided Car Warranty
Increased Fuel Consumption

1. Components Will Wear Off

A car engine features several moving parts. These include valves and pistons. The lubricating properties of your car’s engine oil reduce friction. Therefore, it plays a vital role in protecting those parts.

Engine Oil Will Deteriorate

If you miss your car’s oil change schedule, the engine oil will continue to deteriorate. It will fail to protect the engine’s components from friction fully. This will then wear off components until they get completely damaged.

Major Car Issues

So, if you are asking, can you go a year without an oil change? This might be impossible. After a year or just a few months, you will likely encounter major car issues.

2. Dirt Will Build Up

Helps Remove Small Debris and Particles

The motor oil also helps clean the engine by removing small debris and particles. If your car misses its oil change schedule, it will likely result in dirt buildup.

Plug Oil Channels and Shorten Engine Life

This can then plug oil channels and shorten engine life. Dirt buildup prevents the engine from working efficiently. It can even lead to loss of power.

Sludge Formation

If the motor oil is not changed for a long time, it will gel or solidify in the car’s engine. It will eventually turn into sludge. This will prevent the oil from reaching different parts of the engine. There will be oil starvation in the camshafts, bearings, and crankshafts.

The oil will not reach other valve train components. The last thing you would want to happen is a damaged engine that must be replaced immediately.

3. Engine Will Overheat

Plays an Important Role in Cooling the Engine

If you didn’t know, motor oil also plays a vital role in cooling the engine. The coolant system is not the only part of your vehicle that cools the engine. Interestingly, the motor oil is capable of reaching places that the coolant system can’t reach.

Thicker Due to High Temperatures

But if the oil or its quality deteriorates, its viscosity becomes thicker due to exposure to high temperatures. It then becomes incapable of absorbing heat and tends to allow the engine to overheat. Aside from that, the gaskets can also blow up and other parts to wear and tear.

4. Voided Car Warranty

If you don’t follow the recommended maintenance schedule of your vehicle, its warranty will be voided. This is because there is negligence on your part as a vehicle owner.

Without following the recommended maintenance, your car will encounter engine issues. This will result in higher costs and, unfortunately, your car manufacturer will not reimburse it.

5. Increased Fuel Consumption

Hard Time Running Due to Thicker and Dirtier Oil

If the oil becomes thicker and dirtier, the engine will have a hard time running. Because of this, your car will most likely require you to put in more fuel often to produce the same amount of power. However, your car will release toxic smoke resulting from burned engine oil.

Cheaper to Replace Engine Oil Than Have the Car Repaired for Damages

Having your car’s oil changed may cost you some money. But, the truth is, it is way cheaper than having its engine repaired for serious damages.

If you have your car serviced accordingly, your car will continue to have strong engine performance. At the same time, the engine can even prolong its life span.

Again, how long can you go without an oil change after the light comes on? Allow a mechanic to inspect your car when the oil light is on. Also, avoid driving for too long when this light is illuminated. You only have about two weeks or around 500 miles until the problem worsens.

How Many Months Can You Go Without an Oil Change?

how long can you go past your oil change

Once the oil warning light comes on, make sure to have your car’s oil changed as soon as possible. Some say that they have a busy schedule and can’t bring their car immediately to an auto care shop.

If so, you still have roughly two weeks of “grace period,” which is about 500 miles of driving. Sadly, if you still don’t get to have an oil change within that period, your car will most likely start encountering engine issues.

So, if you are asking, how many months can you go without an oil change? It might not be that long until you start to notice engine failure.

Benefits of Regular Oil Change

You’ll surely reap the benefits when you subject your vehicle to its regular oil change schedule. So, what are these benefits? They are the following:

Engine Efficiency
Better Mileage
Engine Protection

If you maintain fresh oil in your car’s engine, you will prevent it from having excess wear and tear. You will also avoid the buildup of sludge and friction from happening.

Suffice to say that you will be able to protect your engine from any serious damage. Therefore, allowing it to run efficiently and conveniently.

4. Eco-Friendliness

Not having an oil change does not only damage your car. But it also damages the environment.

When driving your car, heat causes the quality of the engine oil to decrease. Also, heat releases gas. So, if the oil is not enough or has poor quality, the gas released from your vehicle will include hydrocarbons. Unfortunately, these are harmful and toxic to the environment.

With fresh engine oil, you will prevent your car from polluting the air.

5. Worry-free Emission Tests

Regular oil changes mean your car will consistently run smoothly too. This lessens, if not eliminates, your worry every time your vehicle undergoes emission tests. Your vehicle will surely pass them without encountering any hassle.

6. Engine Components Are Kept Cool

Engine components will generate too much heat when you drive at high speeds. With fresh oil, there will be proper lubrication and minimal friction. This will prevent engine components from overheating.

7. Extended Engine Lifespan

Dirty and insufficient amounts of oil will surely result in serious engine damage. But if your car undergoes regular oil changes, it will not only maintain its strong engine performance. But you will also be able to extend the life of your car.
