Why 10W-40 Full Synthetic Oil is Necessary

As a car enthusiast, I have always been meticulous about maintaining my vehicle’s engine. Over the years, I have experimented with different types of oils, and I can confidently say that 10W-40 full synthetic oil is essential for optimal engine performance.

Firstly, full synthetic oil is made up of artificially produced chemical compounds that are specifically designed to provide superior lubrication and protection to the engine. This means that it can withstand extreme temperatures and pressures, ensuring smooth functioning of the engine even in harsh conditions.

Moreover, synthetic oils have a higher viscosity index compared to conventional oils, which means they maintain their thickness and protective properties even in high temperatures. This is especially crucial for high-performance engines that generate a lot of heat.

Additionally, 10W-40 refers to the viscosity grade of the oil. The “10W” indicates its ability to flow smoothly at low temperatures while the “40” represents its thickness at high temperatures. This combination makes it an ideal choice for year-round use, providing excellent protection in both hot summers and cold winters.

Furthermore, full synthetic oil has better detergent properties compared to conventional oils. This helps keep the engine clean by preventing sludge and deposit buildup
