How Long Can Your Car Go Without An Oil Change?

Oil replacement ought to be your top priority when it comes to car maintenance to keep everything running smoothly. You run the risk of losing your car if you don’t change the oil when it needs to be changed. Some experts claim that a car can travel 3,000 miles without an oil change, while others assert that it can do so for up to 7,500 miles. Some automobiles have an oil change interval of over 15,000 miles!

Before you can decide how long your car can go without an oil change, you should take a number of things into account. In the article below, CarMats will help you learn more about why you should change your car’s oil and what happens if you don’t by reading on.

Why should you change car’s oil?

Your car needs an oil change for a number of reasons. The oil’s main function is to lubricate the engine and guard against wear caused by friction and grinding. Your engine may perform poorly as a result of oil contamination with dust and dirt over time. See why you should change your car’s oil when necessary by looking at the list below.

Engine Lubrication

The main function of car oil is to lubricate the engine, as was already mentioned. Our cars’ engines are constantly subjected to high heat, pressure, and stress. The engine’s parts interact while it generates power, causing motion and friction.

They require the lubrication provided by car oil in order for those components to function while rubbing against one another without suffering damage. Your car should always have the necessary amount of engine oil in it to operate at its peak efficiency. You can find out how much oil your car needs by reading the owner’s manual or going to the website of the car’s maker.

Engine Temperature

The engine can easily overheat because it operates continuously and experiences constant friction. Overheating and excessive friction are prevented by having enough oil in the engine. The engine will run much better because it can cool off.

Similar to this, not enough oil can cause your engine to overheat and break down.

Improved mileage

Your car’s fuel consumption will be lower if the engine is properly lubricated. You can save money by having your car’s oil changed because it can increase gas mileage by up to 2%. If you don’t change the oil that has become contaminated by dirt, dust, and other foreign objects, the engine will use more fuel.

Less dust and sludge

The engine continuously gathers dust and sludge while it is running, which has an impact on how well it performs. As was already mentioned, the motor and engine’s operation will slow down as a result. The performance of the car will improve and it will stay in good condition if the oil is changed because there will be less dust and sludge.

Expanded engine lifespan

If you perform routine maintenance, your car will appreciate it and run much better. You will increase the lifespan of your engine because new oil makes it much easier for it to operate. When you take into account all of these factors, it becomes obvious that changing your oil is a necessary task that will benefit both you and your vehicle.

Recommendation for oil changes

The frequency of oil changes is determined by the age and configuration of your car. Some people contend that you should change your car’s oil every 1,000 miles. Even for older cars, that happens way too frequently and is not very environmentally friendly.

The majority of auto experts now recommend changing your car’s oil once you’ve driven between 5,000 and 7,500 miles. A more recent vehicle will need fewer oil changes on a regular basis because the frequency of oil changes depends on the age of the car. Older vehicles may find it convenient to change the oil every 3,000 miles, but new vehicles do not require this level of maintenance. Oil changes are much more important for older cars that aren’t in good shape than for newer cars.

Although synthetic oil is significantly more expensive than regular oil, it will benefit your car more. Additionally, some vehicles use synthetic oil to operate. If that applies to your car, you can increase the interval between oil changes to 10,000 to 15,000 miles or more.

What happens if you don’t change car oil regularly?

Long-term car oil change neglect increases the likelihood of engine damage and subsequent high replacement costs. There is no chance for repairs when an engine runs out of oil, so you will always need a replacement in that circumstance. A dry engine will quickly overheat, and its components will deteriorate. After a while, the engine will seize up or blow a gasket, leaving you with nothing but a clicking noise when you try to start your car. That is an obvious indication that the engine in your car is beyond repair.

Can a car last a year without an oil change?

The quick response is no. You shouldn’t let a year pass before changing the oil in your car, even if it hasn’t reached the recommended mileage for an oil change. Oil can spoil if it stays in the engine for too long. It eventually loses its viscosity and is unable to properly lubricate the engine’s parts. Because of this, regardless of mileage, you should change it at least once per year.

How long does it take to change the oil in a car and what’s the price?

It’s not difficult to change the oil in your car. A mechanic should be able to change the oil in your car in between 30 and 45 minutes. The process involves getting rid of the old oil, replacing the filter, and then putting new oil back into the engine.

The oil manufacturer you select will have an impact on the cost. There are cheaper oils and more expensive oil varieties. Furthermore, not all oils can be used in all kinds of vehicles. While changing synthetic oil can cost between $65 and $125, replacing conventional oil can cost between $30 and $75.


As you can see, maintaining your car’s oil is essential for it to run smoothly. It’s crucial to abide by the oil-changing rules if you want a car that runs smoothly and efficiently. Make regular oil changes a habit by determining the recommended oil change mileage for the type of vehicle you drive.
