In today’s hectic lifestyle, on-one has plenty of time to maintain their vehicle. And most people skip that oil change once, then twice, and then find out they’re running late.
And then we face a commonly asked question: What happens if you don’t change your oil? Changing the oil is a critical function of car maintenance.
If you don’t check this off your to-do list and don’t, you create bigger problems down the road. Oil in the engine is vital and regular changes simply should not be skipped.
By avoiding oil change, you might have several negative consequences that can occur in your vehicle. Engine oil plays a crucial role in lubricating, cooling, and cleaning the engine, so neglecting oil changes can lead to various issues
You also need to know how much oil your vehicle needs. If you skip this task for your vehicle. Then you have big problems with your vehicle. In this article, we are going to reveal the functions of engine oil and the major consequences if you do not change the oil.
Top 5 Functions of Engine Oil in Your Car
If you want to know what happens if you don’t change the oil in your car. First of all, you need to know how the oil works in your car.
Engine lubricant is like blood in your car. Without it, you cannot think about the correct operation of your car.
It is critical to the proper operation of engines, reducing fuel emissions, and improving engine performance.
Fuels in engines perform many functions for an engine to function properly over time. These are the main ones:
1. Lubricate Engine Component
Engine oil lubricates engine components in such a way that they can easily pass each other without appreciable loss of performance due to friction.
This is especially true at the beginning. When an engine is stopped, oil tends to enter the oil pan.
Therefore, when the engine is started, the oil must be pumped rapidly through the engine to provide a sufficient starting speed for the engine to rotate.
Once the engine is running, the engine oil must form a film between the moving parts to make them “slippery”, increasing power, performance, and efficiency.
2. Eliminate Engine Wear
One of the main functions of engine oil is to reduce or eliminate engine wear on a variety of components.
It acts as a protective layer and reduces friction when metal parts move on top of each other. Modern oils contain friction reducers to make this protective layer even more complete.
Without this layer, your engine would stall and stop working. This metal-to-metal friction is fatal to any vehicle’s engine, so you should avoid it entirely.
3. Cool Engine Parts
By reducing friction, heat on moving parts is minimized, reducing the overall operating temperature of the device.
Fuels also absorb heat from contact surfaces and transport it to a place where it can be safely distributed, such as an oil pan.
Heat transfer capacity is usually a characteristic of base oil viscosity; lighter oils tend to transfer heat more easily.
4. Protection Against Corrosion
Burning fuel produces corrosive acid that can damage metal parts of the engine. With additives in modern motor oils, corrosion slows down.

However, over time and in contact with oxygen, engine oil can oxidize and no longer fulfill its corrosion-inhibiting function. Therefore, the engine oil must be changed regularly.
5. Form a Seal
The motor oil acts as a dynamic seal in places like the combustion chamber. Helps seal piston rings against the cylinder wall to prevent oil contamination from hot exhaust gases
And maximize engine compression. A good seal also helps keep oil out of the combustion chamber to reduce oil consumption.
These are the main functions of oil in your car. That makes oil an important component of any vehicle.
What Happens if You Don’t Change Oil in Your Car? – 7 Engine Problems
As we discussed major tasks of fuel in your vehicle. Failing to change the oil and the filter on time means you’re running your motor with essentially dirty oil.
Now you will get the answer to your question of what happens if you don’t change the oil in your car. These are the top 7 problems your vehicle faces.
1. Poor Engine Performance
In addition to providing lubrication, oil also keeps your car’s engine clean. Detergents, dispersants, and other additives transport dirt and deposits to the fuel filter, which is replaced when the oil is changed.
Once the filter becomes clogged, all of that debris is forced to circulate back through the engine. Smooth, clean oil gradually turns into dirty mud.
The moving parts of your engine have to fight this sludge, forcing you to work harder. This makes engine performance down.
2. The Wear Down
Engine parts wear out the longer you wait to change the oil. This is because dirty oil is thick and abrasive, so it picks up more and more dirt as it passes through the engine.
It wears out engine parts even though they remain properly lubricated. In general, the longer an oil change is put off, the more problems the engine presents.
Most of the time, your engine gets too hot, which can cause it to run less efficiently.
3. The Loss of Effectiveness
The additives in engine oil that make up the oil, like detergents, dispersants, oxidizers, and friction reducers, wear out over time if the oil has not been changed.
The result is a sharp drop in the oil’s lubricity, which is already being affected by accumulated dirt and debris. Eventually, it gets dirtier and dirtier.
This will not happen after a month but over time and many thousands of kilometers. But fast enough, especially when time goes by and life gets busier and busier.
4. The Complete Engine Failure
Your engine failure happens over time, but it happens when oil is ignored for an extended period. With nothing to prevent the engine’s moving parts from coming into contact.
Metal-on-metal friction causes such severe damage to components that the engine will eventually stall and simply stop running.
This shows the importance of oil, as it is a lubricant that allows the metal to press against metal without damaging it.
5. Engine Overheating
The lubrication by the engine oil helps to keep the engine temperature in the ideal range. When the oil turns to sludge, the friction in your engine increases dramatically.
As the friction increases, so does the average temperature when the vehicle is in operation.
6. The Buildup of Sludge and Deposits
Old, dirty oil can form sludge and deposits in the engine. These contaminants can clog the oil passages, leading to restricted oil flow.
Reduced oil flow means less effective lubrication and cooling, which can result in engine damage and decreased efficiency.
7. Poor Fuel Efficiency
Inefficient lubrication and increased friction due to old oil can lead to decreased fuel efficiency. Your engine has to work harder to compensate for the lack of proper lubrication, which can cause higher fuel consumption.
The Significance of Regular Oil Changes In Your Vehicle
The engine, often referred to as the heart of a vehicle, relies heavily on clean and well-maintained oil to function efficiently. So, we delve into the significance of regular oil changes in your vehicle and highlight the far-reaching benefits they offer.
– Prolonged Engine Life
Oil changes contribute to a longer-lasting engine. With proper lubrication, the engine experiences less stress and wear, leading to a reduced risk of major mechanical issues. This prolongs the overall life of your vehicle.
– Improved Performance
A well-lubricated engine performs optimally, delivering smooth acceleration, responsive handling, and overall enhanced driving experience. Regular oil changes help maintain consistent engine power and responsiveness, ensuring that your vehicle performs at its best.
– Contaminant Removal
Over time, dirt, debris, and microscopic metal particles accumulate in the oil. These contaminants can form sludge if left unchecked, impairing oil flow and clogging vital engine passages.
Regular oil changes remove these impurities, ensuring that the engine operates with clean oil, free from harmful debris.
– Improved Fuel Efficiency
Clean and high-quality oil reduces friction and allows the engine to operate more efficiently. It also requires less energy to function, resulting in improved fuel efficiency and cost savings at the pump.
Some Important Points for You While Changing Oil in Your Car
There are some things you need in your mind while changing the oil in your car. Like which type of oil is required for your car or how much oil is required for your car.
We will discuss these points one by one. So go ahead and read these point:-
1. Types of Oil Required for Your Car
Whether synthetic, synthetic blend, high mileage, or conventional motor oil is best for your vehicle depends on several factors.
- Full Synthetic Oil
Fully synthetic oil is ideal for vehicles that require the best performance and high lubrication.
Fully synthetic oil offers higher viscosity, resistance to oxidation and thermal degradation, and helps combat oil sludge.
- Synthetic-blend Motor Oil
This is the best of both worlds. It is a blend of synthetic and conventional base oils with additives found in both.
It has excellent motor protection properties at a lower cost than fully synthetic.
- Mineral Oil
Mineral oils are formulated in various viscosity classes and quality grades. They are recommended for drivers with a simple engine design and a normal driving style.
- Conventional Motor Oil
Conventional oil is the most commonly used type of oil. It is ideal for new light, low and medium mileage vehicles with a simple engine design.
2. How Much Oil is Required by Your Car
- Well, that depends on your vehicle’s engine. And you should be familiar with oil requirements for your vehicle.
- Most engines require between 5 and 8 liters of oil, depending on the size of the engine. A 4 cylinder engine normally needs around 5 liters of oil.
- A 6-cylinder engine takes about 6 liters. An 8-cylinder engine requires between 5 and 8 liters, depending on the size of the engine.
- This amount also varies depending on whether the mechanic changes the oil filter when changing the oil.
3. How to Check Oil Level For My Car
- Let it cool down for at least ten minutes to allow all of the oil from different parts of the engine to collect in the lower oil pan.
- Make sure the car is parked on level ground. Open the hood and find the yellow dipstick cap, which is usually in the center of the engine bay. Some vehicles also have electronic oil level control which totally depends on the make and model of the car.
- Take out the dipstick and wipe it with a clean cloth. Reinsert the dipstick completely after cleaning. Wait for a second and take it out.
- Note the brand of oil; ideally, it should be between the minimum and maximum grade. If the level is low, add engine oil. Be sure to use the same type of oil to avoid damaging engine parts.
