What Happens If You Don’t Change Your Oil? (5 Failure Signs)


What’s the worst thing that happens to your engine if you don’t change your oil? The answer is simple: it will break down. It might not be right away, but eventually, it will.

Getting an oil change is important because it keeps your engine from breaking down and saves you money. If you don’t remember the last time you took your car out for an oil change, then do it immediately before you get a broken-down car on the side of the road.

It might not be as bad as this scenario, but there are many risks associated with not getting regular oil changes. This blog post is going to explain why changing our oil is so important and what happens if you don’t change your oil.

What does the oil actually do for your engine?

Engine oil is in charge of lubricating different engine parts, especially the engine’s moving parts. Your oil is in charge of preventing wear and tear, which it does by creating a thin layer between two surfaces that avoids unwanted friction.

The oils also help cool down your engines because they are made out of molecules to help absorb heat while transferring it away from an object. Overall it is in charge of keeping all of your engine components running smoothly.

If you don’t change the oil regularly, all of these processes are going to be affected and may lead to some serious problems. Lubrication is essential for your engine to work properly. If the oil is not lubricating and protecting moving parts, it will wear out faster than usual.

Why is it important to change your engine oil?

The main job of the motor oil is to lubricate the metal surfaces, so they don’t rub against each other and get stuck. One of the most important reasons why you should get your oil changed is to avoid overheating. Overheating can be really dangerous, especially when it’s not noticed early.

The engine will start to work less efficiently because of the lack of oil, and you may notice more leaks or other warning signs like white smoke coming out from your exhaust pipe. When you lubricate the motor properly, you will feel how it begins to run smoothly and may even last you for a long time.

If you don’t get your oil changed, it will build up and become a thicker type of gunk that coats all metal parts of the engine, which may cause some serious damage. Also, If you skip oil changes frequently, it can eventually cost you more in the long run since you’ll have to change your car’s engine sooner than expected.

Learn What Happens If You Don’t Change Your Oil Frequently

What Happens If You Don’t Change Your Oil

Your car engine has many moving parts that need a constant supply of oil to work properly. If you don’t change your vehicle’s oil, the engine can become less efficient and may not last as much as if you constantly get regular maintenance done.

Worst case scenario, your car will suffer from complete engine failure. That’s why it is essential to keep your oil changed at least every 3,000 to 5,000 miles, depending on the type of oil that you are using. Here are other things that can happen if your oil is not replaced frequently:

Expect to have poor engine performance

Oil moves throughout your car engine and keeps it lubricated. Without oil, the moving parts inside will grind together, which could lead to major damage or an expensive repair bill. Also, if you don’t change your oil for too long, a piston might break from all of the friction that occurs when they aren’t protected with enough lubricant.

Excess debris build-up in your engine

The entire engine requires five to six quarts of clean oil to prevent sludge and prevent piston seizure. Dirt will also build up in your engine slower than usual. Replacing the old oil with a fresh clean supply will help keep the engine running smoothly.

The excess of debris will cause sludge and other build-ups that will keep the engine running less efficiently than before. The debris can also cause your pistons to seize up, and it can also lead to oil pump failure. When you perform oil changes on time, you are giving your engine the chance to function at its best.

Warranty on your vehicle can be voided

If the manufacturer can prove that you did not replace your motor oil within the scheduled time frame, your warranty can be voided. Allowing a car to go without an oil change for an extended period of time could not only void your warranty but also lead to bigger problems in the future.

We recommend taking your car to a mechanic for oil changes instead of doing it yourself. This way, you can show proof of regular oil changes and avoid accidentally disposing of the five to six quarts of lubricants. Many mechanics will have an industrial oil pan disposal system in place to lessen the burden of disposing the old oil.

Your car can suffer from engine failure

If you don’t change your oil, the engine will overheat. The water pump has to circulate coolant around the block and keep it at an optimum temperature, but if there isn’t enough lubricating oil in place, then this can cause major damage because of overheating.

The excess heat will trigger the car’s cooling system, and sometimes that is the reason you’ll see your radiator fan keep turning even when your car isn’t on. Furthermore, this heat accumulation can cause a gasket to blow, and it can also lead to other problems such as the engine seizing up.

Engine loses its effectiveness

Synthetic oil will typically have an anti-wearing formula that will ensure that the engine doesn’t lose its effectiveness, but it will get dirty over time. One of the benefits of changing your oil according to the vehicle owner’s manual is that it will help prevent lowering your engine’s oil pressure.

Not having the proper oil pressure can cause the engine to work harder; it can be damaged with time. This is because, without enough lubricants, I will create an excess of heat. All of this can lead to a blown head gasket which is a very expensive repair.

How long can a vehicle go without an oil change?

Depending on the type of lubricant that your car uses, the vehicle can go up to 12,000 miles without an oil change. Having a synthetic blend will allow your car to last even longer without needing an oil change. The viscosity level will determine how long the vehicle can go without an oil change.

Regular oil will need to be replaced every 3,000 miles. When using synthetic oil, you can expect an oil interval change of around 5,000 to 10,000 miles. It is important to note that some full synthetic motor oils can last as long as 15,000 miles. Review your owner’s manual to identify what is the type of lubricant that your car engine uses.

Is it bad to go 2000 miles over oil change?

Driving your vehicle to pass 2,000 miles over without getting an oil change is not recommended. Oil moves through your engine and picks up dirt particles from the different engine components. Not replacing your oil according to the manufacturer’s recommendations can cause serious engine damage.

If your vehicle has regular oil, you should get your oil changed every 3,000 miles or after six months have passed, whichever comes first. Most cars that use synthetic oils will have a longer interval change. Many car owners don’t pay much attention to the importance of routine maintenance of their vehicles.

What happens if you don’t change your oil every 5000 miles?

If you own a car or a truck that uses synthetic oil, you should get an oil change depending on the mileage you have driven. If the manufacturer recommends an oil change every 5,000 miles and you drove past them, your motor components will have been deprived of the vital lubricant for too long.

At this point, the motor will not shut itself off, but it will likely be giving off the telltale signs of wear. You do not want to push it because it can lead to engine failure. The importance of oil changes relies on making sure the lubricant is pure and clean. This way, you can protect your engine and avoid an expensive repair in the future.

Is it bad not to change the engine oil for over a year?

Most vehicle owners neglect to take their vehicles to get regular maintenance and forget about changing their oil. A car or truck that has been sitting without an oil change for over a year’s time is at risk of the engine seizing up.

Things can get ugly, especially if you start noticing oil leaks. A motor that starts to leak can be a sign that your motor isn’t functioning efficiently due to the lack of lubrication from old oil and can lead to serious repairs in the future.

What are the benefits of changing your motor oil?

If you don’t get an oil change, the dirt will build up in the motor, which can cause engine failure or major repairs that cost more money than a simple oil change. The wear on critical parts such as pistons, cylinders, bearings, and valves will increase without an appropriate level of cleanliness in the area.

One of the benefits of clean oil running in your engine is that it will help to reduce the heat inside of your motor. Furthermore, the motor components will get that extra protection against wear thanks to the anti-wearing formula of the new oil. Other benefits include the prevention of seized engines, the cooling of components, and avoiding poor fuel economy.

Do I need to change my oil filter when I change my motor oil?

Whenever the lubricants are traveling through the components of your motor, some detergents that are present will start to collect dirt and other particles. These detergents will carry all of the particles to the oil filter, and if it is not replaced, the oil will not be able to circulate properly.

The oil filter is designed to catch all the particles from your engine, but if it becomes clogged up, you need to replace it. Typically your oil filter will be replaced when you take your car to get an oil change. Replacing the oil filter is inexpensive, and it can help you avoid the breakdown of other components of your motor.


Now you understand what can happen if you don’t change your oil, make sure you take the necessary steps to change it on time when maintenance is due. Regular oil changes are important, so do not forget to take action when needed. Your vehicle’s engine will thank you for it.
