How To Choose Right Engine Oil for Your Car: A Comprehensive Guide for Indian Drivers

Introduction

Engine oil is the lifeblood of your car. It keeps your engine running smoothly, protects it from wear and tear, and ensures optimal performance. But with so many grades, types, and brands available, choosing the right oil can feel overwhelming especially for Indian drivers dealing with diverse weather conditions and road types.

In this blog, we’ll simplify engine oil, explain the differences between oil grades, highlight the pros and cons of synthetic and semi-synthetic oils, and recommend the best options for popular Indian car models.

Understanding Engine Oil Grades

You’ve probably seen labels like 5W-30 or 10W-40 on engine oil cans. But what do these numbers mean?

• The First Number (e.g., 5W): Refers to how the oil flows in cold weather. The lower the number, the better it flows in cold temperatures. Here “W” Stands for "Winter," indicating the oil’s performance in cold climates.
• The Second Number (e.g., 30): Indicates the oil’s viscosity at normal operating temperatures. Higher numbers mean thicker oil, offering better protection in high temperatures.

Common Engine Oil Grades and Their Uses

Understanding oil grades is essential to ensure your car performs optimally. Below are the most used engine oil grades and their applications:

• 0W-20: This ultra-thin oil flows easily even in extremely cold temperatures, making it ideal for modern cars and regions with cold climates.
• 0W-30: Similar to 0W-20 but provides enhanced protection at higher operating temperatures. It works well for mixed climates and modern engines.
• 0W-40: Perfect for high-performance engines, this oil grade is designed to withstand extreme weather conditions, ensuring reliable performance in both cold and hot environments.
• 5W-30: A versatile oil grade that balances fuel economy and performance, making it an excellent choice for urban driving and normal conditions.
• 5W-40: Known for its balanced protection, this oil grade is suitable for both city commutes and highway driving, especially in hotter climates.
• 10W-40: Thicker and more resilient, this grade is ideal for older engines or vehicles frequently exposed to varied climates and rugged conditions.
• 15W-40: This heavy-duty oil is built for diesel engines and high-performance vehicles. It offers robust protection in hot climates and for off-road driving.

Each oil grade is tailored to specific conditions, ensuring your engine runs smoothly, no matter where or how you drive. Always refer to your car’s manual to choose the best grade for your vehicle.

FAQs About Engine Oils

Q: Can I mix different engine oils?
Yes, you can mix oils, but it’s not recommended. Mixing oils with different viscosities or types (e.g., synthetic and mineral) can reduce effectiveness and performance. Always use the oil grade and type recommended by your car’s manufacturer.

Q: How often should I change my engine oil?

• Fully synthetic oil: Every 10,000–15,000 km.
• Semi-synthetic oil: Every 7,000–10,000 km.
• Mineral oil: Every 5,000–7,000 km.

Q: What happens if I use the wrong oil?
Using the wrong oil grade or type can increase engine wear, reduce fuel efficiency, and cause long-term damage.

Q: Can synthetic oil be used in older cars?
Yes, synthetic oil can be used in older cars, but consult your car’s manual first. Some older engines perform better with thicker oils like 10W-40.
