What’s the function of car oil?
The following are the major function of a car (motor or engine) oil:
- Friction is reduced by the engine oil.
- Car oil prevents corrosion and rust.
- Engine oil serves as a coolant.
- Car oils assist in purifying the air.
- The engine oil also works as a gap filler.
Friction is reduced by the engine oil
Engine oil has several advantages, but one of the main ones is that it lessens friction and metal-to-metal contact. In order to prevent metal parts from coming into contact with one another, engine oil develops a protective film over the moving elements of the engine.
Car oil prevents corrosion and rust
Rust and corrosion inhibitors are found in engine lubricants, which protect against normal wear and tear. This promotes higher engine performance and extends the engine’s life by decreasing oil oxidation.
Engine oil serves as a coolant
The coolant characteristic of engine oils keeps the upper engine and its operating components cool. It stops energy loss and engine damage in automobiles.
Car oils assist in purifying the air
The majority of engine oils contain detergents as additives that clear the oil of pollutants and other deposits to keep the moving components clean. This aids in protecting the engine from serious harm.
The engine oil also works as a gap filler
The distance between the piston and the cylinder is not particularly smooth. Engine oil fills in gaps and enhances the performance and efficiency of the engine.
How often should you change your car oil?
You’ve probably heard of the 3,000-mile (4,000 km) oil change myth. An oil change is still regarded as necessary every 4,500 kilometers (3,000 miles), despite the amazing advancements in oil chemistry and engine technology that have occurred recently. The majority of automakers really recommend an interval of 11,000 or 15,000 kilometers (7,500 or 10,000 miles) in their service manuals.
So why is this myth still considered to be true? Customers continue to adhere to this conventional guideline since they are unaware of the improvements and advancements taking place in the automotive sector. Instead, by opting to adhere to the suggested oil change interval, not only will you save time and money on maintenance expenditures, but you will also contribute to environmental protection.
What causes engine oil leaks in a car?
We appreciate you asking. The majority of leaks are caused by worn-out engine gaskets, leaks from the oil pan, faulty oil seals, or faulty connections. Check the oil pan seals while crawling below the automobile. Additionally, inspect the oil pan drain plug while you’re there. Next, examine the valve cover gaskets and the timing cover seal. Here, issues may call for pricey, comprehensive repairs.
A broken oil pan is one of the most frequent causes of oil leaks in cars. When the engine isn’t using it, the oil is stored in the oil pan. An oil pan gasket keeps the oil pan separate from the engine block. Oil might spill from a faulty oil pan or gasket. Road debris has the potential to damage these engine bottom-mounted parts. They might become loose or damaged as a result of wear and strain, which could cause a leak.
Is it safe to drive when a car is leaking engine oil?
You and other drivers on the road may be at risk if you drive a car that has an oil leak. Oil can catch fire when it reaches a specific temperature, and your car’s engine can heat up to a point where it could catch fire. But oil can also harm rubber hoses and seals, which might lead to a breakdown. Risking your safety and the safety of others is not worth it. Therefore, you should take your car to the closest garage for repair if you suspect an oil leak.
How can you fix a car oil that is leaking?

Move on to the timing belt cover and finally, the valve covers once the oil pan appears to be snug. Just keep in mind that you must tighten nuts to a specified tolerance and in a specific order depending on the model of your automobile.
You may get these specifications from the majority of car parts retailers. Any leak should be fixed right away, but engine oil leaks require special attention. Knowing the sources of engine oil leaks can help you locate the problem and start the necessary DIY repairs. Don’t ignore it or wait for it to go away. Take initiative. Maintaining the performance of your car will allow you to keep it on the road where it belongs.
