Group I: Commonly used in industrial lubricants where cost is a primary concern, but they have lower stability and performance compared to newer groups.
Group II: Widely used in automotive and industrial lubricants due to their better performance compared to Group I oils.
Group III: Suitable for high-performance applications, including engine oils and other demanding environments.
Group IV: Ideal for extreme conditions, such as high temperatures and cold starts.
Group V: Used in specialized applications, including biodegradable lubricants and high-performance formulations.
