Did you know about the fascinating world of viscosity index? Here are some interesting facts!
Viscosity Index (VI) is a critical rating that determines how an oil's viscosity changes with temperature, making it essential for lubricating oils used in engines and machinery.
Introduced by the Society of Automotive Engineers (SAE) in the 1950s, viscosity index classifies oils based on their viscosity-temperature characteristics.
A higher viscosity index means the oil's viscosity remains stable across a wider temperature range, ensuring consistent lubrication and protection.
High viscosity index oils are a game-changer for automotive engines, providing superior lubrication and protection under various operating temperatures.
The viscosity index is determined by measuring an oil's kinematic viscosity at different temperatures and comparing it to a reference oil.
The VI scale ranges from 0 to 100 or higher, with higher values indicating better viscosity-temperature performance.
Multi-grade oils like 10W-40 or 5W-30 have higher viscosity index ratings, maintaining consistent viscosity across a wide temperature range.
Synthetic oils outshine conventional mineral oils with higher viscosity index ratings, making them ideal for extreme temperature conditions.
Viscosity index improvers (VII) are additives that prevent oil from thinning at high temperatures or thickening at low temperatures.
Selecting lubricants with the right viscosity index is crucial for peak performance and protection of engines, machinery, and mechanical systems.
