Purpose and Specifications
WOLF EXTENDTECH 80W90 LS GL-5 1L is a premium transmission oil designed for manual gearboxes, differentials, and axles in cars, trucks, and tractors. Its 80W90 viscosity flows smoothly in cold starts down to -12°C while staying thick and protective up to 150°C under heavy loads, reducing wear and preventing breakdowns.
Meets tough API GL-5 and military specs like MIL-L-2105C/D, making it safe for yellow-metal parts like brass synchros that some oils damage. The LS (Limited Slip) formula handles locking differentials without chatter. 1-liter bottle perfect for precise top-ups or small fills.
When to Use / Replace?
Use in high-stress conditions like towing, off-road, or commercial driving where gears grind under pressure. Ideal for older vehicles or tractors needing yellow-metal-safe protection.
- Normal driving: Replace every 60,000 km or 3 years to keep shifts smooth and avoid overheating.
- Severe duty (towing, heavy loads): Every 30,000-45,000 km or 1 year.
- Tractor gearboxes: Yearly for commercial use, every 3 years otherwise after first year.
Shelf life: 5 years unopened in cool, dry storage. Check fluid color - dark brown means change now to prevent slipping gears or damage.
