Maintaining the condition of the car is the most important thing for you to do. Especially for used cars whose performance may not be as good as new cars. Therefore, using thin engine oil for used cars is not a good idea.

This can actually make your car's components more prone to damage. Thin oil is certainly not the best choice for your car. It can definitely cause your car's performance to decline when using this thin oil. You should avoid this thin oil which is clearly unsafe.

This is What Happens If You Use Thin Engine Oil in Used Cars

Oil is one of the important things needed by the car engine to function properly. Providing oil of the best quality is one of the things that needs to be carefully considered. If not, the quality of your car's engine may decline.

Not only new cars use the best oil, but used cars do as well. Used cars indeed require more extra care. When using thin engine oil, it is highly discouraged.

This can actually make the car less able to work optimally. It is certain that the use of thin oil is not safe, and this can happen to your car when using thin oil.

1. Oil Becomes Easily Evaporated

Liquid materials will easily evaporate when exposed to heat. This can also happen to oil. However, oil that has strong molecules and a thick texture does not easily evaporate. Unlike thin oil, which is certainly more prone to evaporation.

This thin oil has a low temperature limit, making it easier to evaporate. Especially if the cooling system is not designed for this thin oil. This makes you spend more because you often have to buy oil.

2. Engine Durability May Decrease

Using thin engine oil in used cars can cause the engine's durability to decrease. This situation can occur because the oil cannot work optimally to lubricate the engine components. Especially in car components that have larger gaps. This is what causes components to wear out in a short time.

3. The Engine Has a Rough Sound

In addition, this thin oil can also cause the engine to have a rougher sound. This happens because thin oil can flow more quickly through the engine components. If this occurs, the friction in the engine may decrease.

4. Emission Quality Will Deteriorate

Not all cars have components with larger gaps due to long-term use, especially in older used cars. If using thin oil, it is possible that the oil will also enter the combustion chamber.

If this happens, it can cause the oil to burn, so when your car is fully accelerated, it can emit much worse emissions.

When using a used car, it is not only important to pay attention to the engine components but also to the oil. After all, the function of oil is very important for engine performance. Therefore, make sure to get the best oil for your car.

Using thin engine oil in used cars is indeed not recommended. If you experience damage to your car, have it repaired immediately at an official dealer from www.daihatsu.co.id. Get more interesting automotive information by visiting our website.
