When should you change your car’s oil?

Based on vehicle kilometers driven

Based on vehicle kilometers driven

Changing engine oil depends on the number of kilometers the vehicle has traveled. The general recommendation from researchers is to change the oil every 3,000 – 5,000 km (or 3 months) or according to the manufacturer’s regulations. However, there are some luxury cars that use premium lubricants that can extend the oil change interval up to 8,000 km. Changing the oil periodically according to the number of kilometers traveled helps ensure the oil is always in good condition to lubricate and protect the engine.

Use the oil dipstick to check

Use the oil dipstick to check

A simple method to check the oil level in the engine is to use a dipstick. When the engine is cold, check the oil level and make sure it is not lower than the minimum level (min) marked on the dipstick. When the engine is hot, recheck and make sure the oil level does not exceed the maximum level on the dipstick. Checking the oil level periodically and adjusting it if necessary helps ensure the engine is operating in optimal condition and avoids problems related to insufficient or excessive oil levels.

Observe the oil color

Observe the oil color

Car owners can also rely on oil color to determine when to change the oil. A black oil color usually indicates that the oil is too old and dirty, and the oil needs to be changed to ensure smoother and more stable vehicle operation. A yellow or orange oil color may indicate that the oil is still in relatively good condition and can be used without an immediate oil change. However, if the color of the oil changes significantly, such as black or cloudy, the oil should be changed immediately to ensure engine safety and performance.

What are the consequences of forgetting to change car engine oil?

Reduces friction

After using for a period of time, the viscosity of the oil will decrease. This results in a reduced ability to reduce friction between the engine surfaces that the oil contacts. When this situation occurs, the engine will operate heavily and emit loud sounds during operation.

The level of impact on the vehicle’s operation is very large. Additives in the oil will oxidize after a period of use and this reduces the oil’s anti-wear ability. If you continue to use oil with reduced viscosity and containing oxidized additives, the engine will quickly wear out and its operating capacity will be significantly reduced.

The engine is clogged with dirt

The engine is clogged with dirt

Dirt and iron filings are retained in the oil thanks to its suspended nature, to avoid direct contact with metal surfaces and help clean the engine. However, at some point, when the amount of dirt exceeds the allowable limit, they will become abrasive particles that quickly wear out the engine.

If you do not change the oil regularly, the engine will heat up significantly during operation. This happens due to the cooling ability of the additives contained in the oil, but over time their quality decreases. This results in the oil’s cooling ability also being reduced, and the engine will become hotter during operation.

Reduced engine cooling efficiency

Reduced engine cooling efficiency

During car operation, heat generated from the combustion of fuel in the engine is quickly released. To ensure the engine cooling process is effective, lubricant is one of the important factors. Lubricants help absorb and remove heat from the engine out of the cooling system.

However, if the oil is not renewed and replenished periodically, the cooling effect will decrease. During use, lubricating oil will oxidize, decompose and lose its good lubricating properties. This results in the oil no longer being able to effectively resist friction and dissipate heat. When cooling efficiency is reduced, the engine will experience high temperatures, increasing the risk of fire and explosion and causing serious damage to engine components.

Causes fuel wasting

Causes fuel wasting

In addition to affecting the engine’s cooling efficiency, not changing the oil regularly also causes increased fuel consumption. When the oil is not replaced on time, the lubricating ability of the oil will be significantly reduced. When the engine is running, the internal parts will create greater friction due to not enough lubricant to reduce friction. This leads to increased temperature and the machine gets hotter during operation.

When the engine operates at higher temperatures and the machine gets hotter, combustion is ineffective and fuel combustion processes do not achieve optimal efficiency. This results in the engine using more fuel than it normally consumes. Furthermore, the performance of engine protection additives is also reduced when the oil is not changed on a regular basis, thereby causing a negative impact on the vehicle’s fuel efficiency.

Releases harmful emissions

Releases harmful emissions

Old lubricants are more likely to burn more easily and create harmful emissions during engine operation. As oil becomes old and loses its good lubricating properties, it may not be able to meet the basic requirements to maintain efficient combustion in the engine. This can lead to the generation of large amounts of harmful emissions during combustion.

Things to note when changing car engine oil?

Things to keep in mind when changing car oil

Choose the right type of lubricant

Choosing the right type of lubricant is an important factor to ensure the vehicle operates more stably. Each type of vehicle has different requirements for lubricants, so car owners need to learn and choose the type of lubricant suitable for the car brand and engine they use. Using the right lubricant will help the engine operate efficiently, protect and prolong the life of important parts.

When performing the oil change process, make sure to pour the correct volume of lubricant needed for the vehicle’s engine. Information about appropriate lubricant capacity is usually listed in the user manual or can be consulted from the manufacturer. Adding too little oil will cause under-oiling and insufficient lubrication, while adding too much oil can put excessive pressure on components and cause oil to leak out.

Note the position of the oil drain screw

During the oil drain process, car owners need to pay attention to the position of the engine oil drain screw and transmission oil drain screw. Thoroughly checking and ensuring the oil is drained in the correct location will avoid accidentally discharging the oil and causing unwanted consequences. Draining the wrong oil can reduce engine performance and cause damage to important components.

Check the oil before changing new oil

Before changing car oil, car owners need to check the oil level to determine whether the car still has oil or no oil, and the color of the oil. After pouring oil into the engine, clean the oil cap as well as around the oil filling position. This helps avoid contamination of the oil with impurities.

Remove all old oil

When pouring new oil into the engine, the car owner needs to make sure to clean the oil cap as well as the area around the oil filling location. This helps prevent peripheral impurities from getting into the new lubricant.

Next, when changing new oil, you need to drain all the old oil from the engine and replace the new oil filter or clean the old oil filter. Doing this helps remove impurities, dirt and contaminants that can accumulate in old oil as well as on the oil filter. Cleaning and replacing the oil filter both help ensure that the new oil is not contaminated and that the vehicle is able to operate smoothly and efficiently.

Change oil regularly

Finally, the most important thing is to change the oil at the correct intervals recommended by the manufacturer or according to the number of kilometers traveled by the vehicle. However, for vehicles that frequently operate in harsh conditions or adverse environments, you should consider changing the oil earlier than the expected interval to ensure the best lubrication and protection for the engine.
