Why 10W40 Semi Synthetic Motor Oil is necessary?

As a car owner, I have always been conscious about the maintenance and performance of my vehicle. One crucial aspect of car maintenance is choosing the right motor oil. After extensive research and personal experiences, I have come to realize the importance of 10W40 semi synthetic motor oil.

Firstly, the number 10 in 10W40 refers to the oil’s viscosity at low temperatures. This means that even in cold weather conditions, the oil will flow smoothly and reach all parts of the engine quickly. This is important as it prevents engine wear and tear during start-up, which can cause long-term damage.

Moreover, the number 40 indicates the high-temperature viscosity of the oil. This means that even in high temperatures, such as during long drives or heavy traffic, the oil will maintain its thickness and protect the engine from overheating. This is crucial for maintaining engine performance and efficiency.

Additionally, semi synthetic motor oils are a blend of conventional and synthetic oils. This combination provides better protection against wear and tear compared to conventional oils. It also helps to reduce friction between moving parts of the engine, resulting in improved fuel economy.

Furthermore, semi synthetic motor oils have a longer lifespan
