STARKOL GEARMAX SYNT
75W-80 / 75W-90
Product Overview
STARKOL GearMax GL-5 Synt is enginee-red to deliver consistent protection and reliable performance for modern driveline systems. Produced with premium synthe-tic base stocks and a balanced EP additi-ve system, it maintains stable lubrication under extreme pressure and high ther-mal stress.
Its optimized formulation allows precise gear engagement and smooth operati-on even in low-temperature conditions, while resisting oxidation and degradati-on during extended drain intervals. This makes it a strong choice for heavy-duty commercial vehicles, high-performance drivetrains, and modern transmission and differential applications where API GL-5 level performance is required.
• Advanced EP formulation for extreme load and pressure
• Smooth shifting and reliable performance in low temperatures
• Excellent thermal stability and resistance to oxidation
• Long service life in demanding operating environments
