Ever wondered why modern engine oils perform flawlessly in both summer heat and winter chill? The secret lies in Viscosity Index Improvers (VIIs).
These smart polymer additives adjust oil thickness with temperature, ensuring consistent lubrication and protection. Without them, multi-grade oils wouldn’t exist. That’s why choosing quality VIIs from trusted sources like Top Polymers keeps your machinery running smoothly all year round.
