How to Determine the Best Engine Oil for Your Car?

All the cars we encounter are equipped with a variety of fluids periodically to maintain the mechanical components that propel the car and provide it with sufficient power to smoothly complete its journey. Among these fluids, the most crucial is engine oil, available in various types and viscosity grades to suit different engine types.

Best Engine Oil for Cars

Continue reading this article to understand the primary function of engine oil, the types of oils available in the market, the best engine oil for cars, and how to choose it.

What is the Function and Importance of Engine Oil?

The primary function of engine oil is to facilitate the movement of engine components without friction, preventing wear and corrosion. Additionally, it helps eliminate impurities resulting from the combustion process, all while maintaining the engine’s temperature.

Types of Engine Oil

Engine oil is available in various types based on its chemical properties, influenced primarily by temperature variations. Most manufacturers strive to offer high-quality oils that adapt to different conditions. The main types of engine oil are:

Mineral Oils

  • Oldest type of oils primarily used in older cars.
  • High viscosity.
  • Composed of refined crude petroleum oil.
  • Economical.

Synthetic Oils

  • Purer than mineral oils.
  • Suitable for most modern car engines, enhancing performance and longevity.
  • Lower viscosity than mineral oils, facilitating movement between engine parts.
  • Suitable for use in various temperature ranges.
  • Ideal for sports cars.

Semi-Synthetic Oils

  • Blend of synthetic and mineral oils.
  • Provides better performance across temperature variations.
  • Offers different density levels due to the combination of oils.
  • More affordable than fully synthetic oils.
  • One drawback is increased fuel consumption due to its density.

Choosing the Right Oil Viscosity Grade

Oil types not only differ among manufacturers but also in viscosity grades, playing a crucial role in selecting the appropriate oil for your car. The importance of viscosity grade lies in temperature variations and the region in which the car operates. In extremely hot regions, drivers generally need oil with a high viscosity grade to prevent it from becoming too fluid, resembling water, and reducing its movement between engine parts.

Conversely, in colder regions, drivers require oil with a lower viscosity grade to avoid oil freezing between engine parts and hindering its operation.

This information is typically available on the product packaging using symbols and numbers, including:

  • The letter “W” indicates suitability for cold regions.
  • The number to the right of the “W” represents the appropriate temperature for summer days.
  • The number to the left of the “W” indicates the suitable temperature for winter days.

How to Determine the Best Engine Oil for Your Car?

Refer to the user manual provided with your car upon purchase, as each manufacturer specifies the best oil type for their cars based on the user’s region and environmental conditions.

In conclusion, understanding the role of engine oil, the available types, and selecting the right viscosity grade is crucial for maintaining your car’s optimal performance and longevity.
