Purpose and Specifications

RAVENOL MZG SAE80 GL-4 4L is a premium mineral-based transmission oil designed for manual gearboxes, differentials, and steering gears in older vehicles. It delivers smooth shifting, strong wear protection under heavy loads, and reliable performance from -30°C cold starts to 150°C high-heat conditions.
