Purpose and Specifications

The COMMA SX75W90 GL5 5L is a semi-synthetic transmission oil designed for modern five and six-speed gearboxes and differentials. It meets API GL-5 and GL-4 standards, ensuring strong protection under high pressure while flowing smoothly at low temperatures down to -42°C for easy cold starts.

• Use in vehicles specifying 75W-90, 80W-90, or 85W-90 GL-5/GL-4 oils for hypoid gears and manual transmissions.
• Ideal shelf life of 5 years from manufacture date (check bottle code YYYY.MM.DD) - store away from extreme heat.
