Introduction

Base oils serve as the foundation for lubricants used in both engines and transmissions. They play a critical role in ensuring optimal performance, longevity, and efficiency of automotive components.

Base Oil in Engines and Transmissions

Base oil is a refined petroleum product that constitutes 70 to 90% of the total lubricant volume. It provides the essential properties of lubrication, including viscosity, thermal stability, and oxidation resistance.

Types of Base Oils

Base oils are classified into five groups by the American Petroleum Institute (API):

1. Group I: Solvent-refined mineral oils with lower viscosity index (80-120 VI).
2. Group II: Hydrotreated mineral oils with improved oxidation stability and higher viscosity index (90-140 VI).
3. Group III: Highly refined, hydrocracked oils with viscosity indices above 120.
4. Group IV: Polyalphaolefins (PAOs), a type of synthetic oil, with superior properties.
5. Group V: All other base oils, including esters and silicones, which are used in specific applications.

Functionality and Performance

Base oils provide several crucial functions:

• Viscosity Control: Essential for forming a lubricating film to prevent metal-to-metal contact. The viscosity index is critical for performance across temperature ranges, with higher indices indicating better performance.
• Thermal Stability: Base oils must withstand high temperatures without breaking down, a key requirement for engines and transmissions prone to heat exposure.
• Oxidation Resistance: A measure of how well the oil resists chemical breakdown when exposed to oxygen, crucial for long-term performance and preventing the formation of sludge and varnish.
• Lubrication Efficiency: Directly affects fuel economy and engine efficiency by reducing friction and wear between moving parts.

Numerical parameters often evaluated include pour point (low-temperature fluidity), flash point (resistance to ignition), and viscosity index.
