This prevents welding and scoring of the gear teeth, which is essential for heavy-duty towing or off-road driving conditions where shock loads are frequent. Gear teeth do not slide against each other; they essentially roll and grind, creating immense contact stress.
80w 90 Gear Load Pressure Handling and Performance Under Stress
Temperature Fluctuations and Stability One of the greatest challenges in lubrication is managing the thermal breakdown of the fluid. Understanding the specific requirements of your machinery is the first step in ensuring longevity and peak performance.
While 80w 90 is durable, it is not impervious to contamination. This low-temperature rating ensures the oil remains fluid enough to flow and provide lubrication during cold starts, preventing dry friction.
