Description
When your transmission starts whining or your differential gets noisy after a long day in the field, it’s usually telling you the gear oil needs attention. Lucas Heavy Duty 80W-90 is formulated specifically for the demanding conditions that farm equipment faces—from the heat buildup during heavy pulling to the constant shifting that comes with loader work around the farmyard.
What You’re Getting
- Multi-viscosity formula that flows when cold but protects when things heat up under load
- Heavy-duty additives that extend gear life and reduce wear on expensive transmission components
- Superior film strength that maintains lubrication even under extreme pressure and shock loads
- Thermal stability that prevents breakdown during extended high-temperature operation
- Compatible with seals and gaskets to prevent leaks and maintain proper fluid levels
Built for Real Farm Work
This 80W-90 gear oil is designed for manual transmissions, differentials, and final drives in tractors and agricultural equipment where manufacturers specify this viscosity grade. From compact utility tractors doing chore work to row-crop machines pulling heavy tillage equipment, this oil maintains proper lubrication under the varying loads and temperatures that farm work demands.
Made to Last
Lucas formulates this gear oil with high-quality base oils and proven additive packages that resist oxidation, prevent foam formation, and protect against rust and corrosion. The heavy-duty formula stands up to moisture contamination and maintains its protective properties even when service intervals get stretched during busy seasons.
Good to Know
Always check your operator’s manual for the correct viscosity and specifications before changing gear oil. This oil works well in both wet brake and dry brake applications, but verify compatibility with your specific tractor model. A magnetic drain plug helps catch metal particles and gives you an idea of internal wear when you change the oil.
