Purpose and Specifications

Castrol Transmax Manual EP 80W 1L is a reliable mineral-based transmission oil designed for manual gearboxes in older European vehicles, especially Mercedes-Benz light trucks and ZF transmissions. It meets strict standards like MB 235.1, API GL-4, and ZF TE-ML 17A, ensuring smooth gear shifts and long-lasting protection.
