Gear oil is easy to overlook—until something goes wrong. A noisy final drive, worn planetary gears, or sudden power loss can all point to a single cause: lubricant failure.
Many don’t realize that gear oils are engineered fluids, not just oil. They’re packed with chemical additives that do far more than reduce friction—they help your equipment run cooler, cleaner, and longer. These additives reduce wear, prevent corrosion, fight sludge, and help the oil survive extreme pressure and temperature. Without them, even top-tier base oil won’t cut it.
This Shop Talk Blog post covers what gear oil additives do, how they work, and why they're essential for protecting your final drive motor gearbox. And whether you operate compact track loaders or full-sized excavators, knowing what’s in your oil helps extend service life and avoid costly repairs.
