Why 10W 40 Full Synthetic is necessary?

As a car enthusiast, I have learned the importance of using high-quality engine oil for optimal performance and longevity of my vehicle. After extensive research and personal experience, I have come to the conclusion that 10W 40 full synthetic oil is necessary for several reasons.

Firstly, full synthetic oil offers superior protection and lubrication compared to conventional or synthetic blend oils. It is specially formulated with a combination of base oils and additives that provide better resistance to heat, oxidation, and sludge formation. This means that it can withstand higher temperatures without breaking down, ensuring your engine stays well-lubricated even under extreme conditions.

Moreover, 10W 40 full synthetic oil has a lower viscosity which allows it to flow more freely through the engine, reaching all the crucial parts that need lubrication. This results in reduced friction between moving parts, leading to improved fuel efficiency and a smoother driving experience. Additionally, its low volatility helps reduce oil consumption and keeps your engine cleaner by preventing deposits from forming.

Furthermore, full synthetic oils are known for their longer drain intervals compared to conventional oils. While most conventional oils need to be changed every 3,000-5,000 miles,
