Different Types Of Engine Oil Grades In India

This article provides a comprehensive guide to understanding engine oil grades in India, focusing on mineral oils and high-performance synthetics. It aims to help readers make informed decisions about the right oil for their vehicle and driving conditions. The article explains the SAE and API classifications of engine oil grades, allowing readers to choose the right oil for their specific needs. The goal is to help readers navigate the complexities of lubrication and ensure their engine runs smoothly.

Common Engine Oil Grades In India

With variations depending on the type of oil (mineral, semi-synthetic, fully synthetic) and specific needs, such as high mileage engines, the most appropriate grade will depend on the manufacturer's recommendations and the climate in which the vehicle is driven. In India, common engine oil grades are 5W-30, 10W-30, 15W-40, and 20W-50. Always check your car manual to determine the best oil grade for your vehicle.

Common Engine Oil Grades In India

Synthetic oil grades include 0W-20, 5W-30, 10W-40, and 15W-50, offering superior performance, engine protection, and efficiency across various temperatures.

5W-30:

Ideal for most modern gasoline engines in moderate climates, providing excellent cold-start performance and reliable overall protection.

10W-30:

Slightly more viscous than 5W-30, making it a good choice for older vehicles or regions with warmer temperatures.

15W-40:

A thicker oil commonly used in older diesel engines or high-performance vehicles operating in hot climates.

20W-50:

A highly viscous oil suited for extreme heat conditions or specialized high-performance applications.

A Key Point To Notice About Engine Oil Grads

Viscosity Grade

The Viscosity grade or classification is applied to lubricating oils to indicate their thickness (viscosity) and their flow characteristics at high and low temperatures. Usually defined using the SAE (Society of Automotive Engineers) viscosity grading system for engine oils and the ISO VG (International Standards Organization Viscosity Grade) system for industrial lubricants.

SAE Viscosity Grades (for Engine Oils)

SAE viscosity grades are expressed as a number, sometimes followed by a "W" (for winter), indicating how the oil performs in cold and hot temperatures.

Single-Grade Oils: SAE 30, SAE 40, SAE 50 (Used in specific conditions, without multi-temperature performance)
Multi-Grade Oils: SAE 5W-30, SAE 10W-40, SAE 15W-50 (Designed to perform well in both cold and hot temperatures)

ISO VG (Viscosity Grade) System (for Industrial Oils)

ISO VG ratings classify oils based on their viscosity at 40°C. Common grades include:

ISO VG 32 (Light oil, used in hydraulic systems)
ISO VG 46 & 68 (Medium-weight oils for machinery)
ISO VG 100 & above (Thicker oils for heavy-duty applications)

Types Of Engine Oil

Engine oils are categorized into three types: Mineral, Semi-Synthetic, and Fully Synthetic, each with unique characteristics and suitability for different engines and driving conditions.

Mineral Engine Oil

Mineral engine oil, derived from refined petroleum, is affordable but less effective than synthetic oils, best for older vehicles and motorcycles. It requires frequent replacement and is less effective at high temperatures.

Semi-Synthetic Engine Oil

Semi-synthetic engine oil, or synthetic blend oil, is a blend of mineral oil and synthetic oil, providing superior performance and protection while being more affordable than fully synthetic oil, although it lacks the same level of protection.

Fully Synthetic Engine Oil

Fully synthetic engine oil offers superior performance and protection, with extended oil change intervals and excellent performance in extreme temperatures, but is more expensive than other types.

Conclusion

In conclusion, Selecting the right engine oil grade is crucial for optimal vehicle performance, longevity, and fuel efficiency in India's diverse climates. Multi-grade oils like 5W-30 and 10W-40 are popular, while thicker oils like 15W-40 or 20W-50 are preferred for older engines and hot climates. Automotive lubricants reduce friction, enhance engine performance, and protect vehicle components for smooth operation and longevity. GARS offers a variety of products such as Coolant Oil.
