Why 10W 40 Fully Synthetic Engine Oil is necessary?

As a car enthusiast, I have learned the importance of using the right engine oil for my vehicle. After doing extensive research and consulting with mechanics, I have come to the conclusion that 10W 40 fully synthetic engine oil is necessary for optimal engine performance and longevity.

Firstly, fully synthetic oil is made up of artificial compounds that are designed to withstand extreme temperatures and conditions. This means that it provides better lubrication and protection for your engine compared to conventional or semi-synthetic oils. With its advanced formula, it can flow smoothly through your engine even in cold weather, reducing wear and tear on crucial engine components.

Moreover, 10W 40 refers to the oil’s viscosity rating. The “10W” indicates its viscosity at low temperatures, which means it flows easily during start-up when your engine is cold. On the other hand, the “40” represents its high-temperature viscosity, which ensures proper lubrication and protection when your engine is running hot. This balance of viscosity makes it suitable for both extreme weather conditions.

Using fully synthetic 10W 40 engine oil also offers extended drain intervals compared to conventional oils. This means less frequent oil changes,

This results in improved fuel efficiency and overall performance of the vehicle. Additionally, they have a longer lifespan compared to conventional or semi-synthetic oils, ultimately saving you money in the long run.

Factors to Consider Before Buying

When purchasing any product, it is essential to consider certain factors to ensure you are making the right choice. Here are some things you should keep in mind while buying a bottle of 10W 40 fully synthetic engine oil:
