Choosing the right engine oil for your car is crucial to ensure optimal engine performance, prolong your vehicle’s lifespan, and reduce maintenance costs. This comprehensive guide aims to help all Singaporean drivers make an informed decision when selecting the most suitable engine oil for their cars.

In this guide, we’ll cover the basics of engine oil, factors to consider when choosing engine oil, how to select the right engine oil for your car, and some common misconceptions.

1. Understanding Engine Oil

Basic composition of engine oil

Engine oil is composed primarily of base oil and additives. The base oil is responsible for lubricating moving parts, while additives serve various functions, such as reducing friction, protecting against corrosion, and keeping the engine clean.

How engine oil works

Engine oil lubricates moving engine components, reducing friction and wear, and helps dissipate heat. It also prevents the buildup of sludge and harmful deposits, keeping the engine clean and running efficiently.

Different types of engine oil

There are three main types of engine oil: conventional, synthetic, and semi-synthetic. Conventional oil is derived from crude oil, while synthetic oil is chemically engineered for improved performance. Semi-synthetic oil is a blend of conventional and synthetic oils.


2. Factors to Consider When Choosing Engine Oil


Viscosity refers to the oil’s resistance to flow. Choose an engine oil with the right viscosity grade for your car’s specific requirements, as indicated in your owner’s manual.

API Certification

Look for engine oils that meet the American Petroleum Institute (API) certification, which ensures that the oil meets specific quality and performance standards.

Synthetic vs. Conventional Oil

Consider whether synthetic or conventional oil is more appropriate for your car, taking into account factors such as driving conditions, climate, and your car’s age and mileage.

Car Age and Mileage

Older cars with higher mileage may benefit from engine oils designed specifically for high-mileage vehicles, which contain additives to help protect and restore aging engine components.


3. Choosing the Right Engine Oil for Your Car

Referencing car owner’s manual

Always consult your car owner’s manual for the manufacturer’s recommended engine oil type and viscosity grade.

Seeking advice from a professional mechanic

Consult a professional mechanic for expert advice, especially if your car has unique requirements or if you’re unsure about which engine oil to use.

Factors to consider for Singaporean drivers

Singapore’s hot and humid climate may necessitate the use of engine oils with better heat resistance and stability. Consider synthetic oils or those with a suitable viscosity grade for such conditions.


4. Common Misconceptions About Engine Oil

Myth #1: Thicker oil is always better

Thicker oil is not always better, as it may not flow as easily in cold temperatures or provide adequate lubrication in specific engines. Always choose the recommended viscosity grade for your car.

Myth #2: Synthetic oil is always better than conventional oil

While synthetic oil typically offers better performance and protection, it may not always be necessary for your car. Consult your owner’s manual and a professional mechanic to determine the best choice for your specific situation.

Myth #3: Engine oil should be changed every 3,000 miles

This outdated rule may not apply to modern engines and high-quality engine oils. Refer to your owner’s manual for the recommended oil change interval.


Selecting the right engine oil for your car is essential for maintaining optimal performance and prolonging your vehicle’s lifespan, especially in Singapore’s unique climate.

Understanding the basics of engine oil, considering factors such as viscosity, API certification, and your car’s age and mileage, and seeking advice from professionals can help Singaporean drivers choose the right engine oil for your car. Debunking common misconceptions about engine oil will also aid in making informed decisions.

We hope that you can make an educated decision that will not only protect your engine but also contribute to a safer, smoother, and more enjoyable driving experience. Remember to consult your car’s owner’s manual and seek advice from professional mechanics to ensure you choose the most suitable engine oil for your vehicle’s specific needs.
