Why Synthetic Gear Oil Is Popular in India – 2025 Guide
As the Indian automotive industry continues to evolve with modern technologies and high-performance vehicles, the demand for advanced lubrication solutions has grown significantly. Among these, synthetic Gear oil has emerged as a preferred choice for both personal and commercial vehicle owners in 2025. The shift from conventional mineral-based lubricants to synthetic alternatives is no longer just a trend—it’s a necessity driven by performance, efficiency, and climate adaptability.
In this blog, we’ll explore why synthetic gear oil is gaining popular in the Indian automotive market, what makes it superior to traditional oils, and how it supports long-term vehicle health in varying Indian road and climate conditions.
What Is Synthetic Gear Oil?
Synthetic gear oil is a lubricant formulated using chemically engineered base oils, unlike mineral gear oils which are derived from crude oil. These base oils are designed for optimal performance under extreme pressure, temperature variations, and load-bearing conditions. Synthetic gear oils also include advanced additive packages that enhance wear protection, oxidation resistance, and thermal stability.
Why Synthetic Gear Oil Is Becoming the Preferred Choice in India
1. Better Performance in Extreme Temperatures
India faces diverse climatic conditions, from the intense heat of Rajasthan to the chilly winters of Himachal Pradesh. Synthetic gear oils are engineered to maintain consistent viscosity and optimal flow, ensuring reliable performance across these extreme temperature variations. This ensures consistent performance in both high-temperature urban driving and cold-start conditions in northern regions.

2. Improved Fuel Efficiency
Synthetic gear oils reduce internal friction within gear systems, resulting in less power loss and improved fuel economy. With rising fuel prices, this advantage is significant for commercial fleets and individual vehicle owners alike.
3. Extended Oil Change Intervals
Compared to mineral gear oils, synthetic oils offer longer service life due to better oxidation stability and thermal resistance. This reduces the frequency of oil changes, leading to lower maintenance costs and reduced vehicle downtime—especially valuable for logistics and commercial vehicles.
4. Superior Protection for Modern Transmissions
Modern automotive gear systems, including manual transmissions and differentials, are engineered with tight tolerances and operate under heavier loads. Synthetic gear oils such as EP-90 and EP-140 provide enhanced film strength and anti-wear protection, making them ideal for high-performance applications.

5. Resistance to Oxidation and Breakdown
Indian driving conditions often involve stop-and-go traffic, high ambient heat, and heavy loads, which accelerate oil breakdown. Synthetic gear oils resist oxidation and thermal degradation much better than mineral oils, keeping gear components clean and well-lubricated over time.
6. Enhanced Load-Carrying Capacity
Synthetic gear oils contain high-performance Extreme Pressure (EP) additives that provide a protective barrier between metal surfaces. This ensures durability even under heavy loads and shock loading conditions, common in commercial vehicles and SUVs.
Applications of Synthetic Gear Oil in the Indian Automotive Market
- Passenger cars: For manual transmission and rear-wheel drive systems
- Commercial trucks & buses: In differentials and heavy-duty gearboxes
- SUVs & off-road vehicles: Operating in rough terrains with high torque demands
- Two-wheelers: For efficient transmission and clutch performance
- Tractors and agricultural vehicles: Where long-lasting protection is essential in harsh field conditions
