Many cars’ owners underestimate when to change the oil, and some of them don't even know that it should be changed at a certain time or at a certain number of kilometers, and this is wrong, and may even be disastrous at times if the oil remains unchanged for a longer period than necessary.
Every car manufacturer mentions the period when the oil should be changed in the owner's manual in addition to the full oil information such as its quality and the correct caliber suitable for the engine, so changing it is very important to preserve the engine and its internal parts, so you should pay a lot of attention to changing the oil on time to ensure that your car works without issues.

What will happen if the engine oil is not changed?
If you want to know what will happen to your car's engine if you don't change the oil for a long time, you should read the following:
Poor performance
One of the most important disadvantages of not changing the oil is significantly weakening the performance of the engine, when the oil change periods are long, it loses its elements that ensure good lubrication of the engine parts, in addition to losing heat faster, and when it loses these elements, the performance will be greatly affected and will be accompanied by higher fuel consumption for sure, and when you change it, you will immediately notice the difference in performance and the engine will become more active, responsive and powerful.
Increased fuel consumption
Neglecting to change the oil can lead to increased fuel consumption due to the increase in engine temperature and the decrease in internal pressure in addition to the weakness that will occur in the cooling process, and all this will lead to higher fuel costs over time than the cost of the oil change itself on the scheduled date, and remember that the longer the oil change period, the more fuel consumption will increase.
Engine overheating
The oil works to lubricate and cool the engine parts, and when exceeding the recommended intervals for changing it, its components will weaken and become unable to lubricate the engine efficiently, which leads to overheating, and the temperature of the oil will remain high due to the damage that affected its molecules and components that helped reduce its temperature when it descended to the oil pan under the engine and exposed to the external air that draws heat from it, and the engine's high temperature means reduced efficiency, increased wear and increased risk of permanent damage with increased fuel consumption.

Turbo damage
Turbochargers or turbos use the energy generated from wasted exhaust gases to enhance power, efficiency and performance, and the turbo has become used in many modern cars today, especially those with small engines, with the aim of achieving the highest performance while maintaining fuel consumption within the logical limit, and the turbo of course needs oil to work smoothly, and damage or lack of oil may lead to overheating and damage to the turbo, and if it fails, its debris will enter the engine, which leads to serious damage.
Components and systems affected
The car's engine contains sensitive components and systems that help it work without issues, as these systems such as variable valve timing, turbo, and sensors depend on good oil flow, and any decrease in its quantity, quality, or viscosity can disrupt these systems or components, and this can lead to possible clogging due to the accumulation of dirt and iron filings inside them; because the oil does not do its job perfectly because it has not been changed.
It will affect the car's warranty
There are many car companies that care about maintenance appointments, especially oil changes, and the warranty on the engine will be considered invalid if you are too late to change the oil and miss the appointment by a long time, which means that any breakdown, free maintenance or free oil change will be canceled because you did not adhere to the regular maintenance appointments simply, and the payment will be from your own pocket, so pay attention to this matter.

Reduced value of the car
The delay in changing the oil permanently will affect the engine, and this will reduce the price of your car when you want to sell it if you do not adhere to the recommended change dates from the manufacturer of your car or the manufacturer of the oil you use, as a well-maintained engine and regularly changed oil will be better during inspections and test drives, and the maintenance records in the dealership can enhance the selling price, and you will be the winner in the end.
Increased harmful emissions into the environment
Additional fuel consumption often leads to increased harmful and toxic emissions mainly caused by the combustion of oil due to the wear of internal engine parts, the more wear on the cylinder walls means more oil is burned, and it will come out as toxic gases from the exhaust system and will affect human health and the environment as well.
