Introduction: Why Oil Matters for Air-Cooled Motorcycle Engines Air-cooled V-Twin engines operate under thermal stress levels far higher than most liquid-cooled designs. Cylinder head temperatures can exceed 380°F in heavy traffic or summer conditions, compared to roughly 200°F in a liquid-cooled counterpart. With no coolant system to buffer these extremes, the burden of both lubrication […]

Introduction Hydrostatic transmissions are the backbone of zero-turn mower performance, relying on hydraulic pumps and motors to transfer engine power directly to the wheels. Unlike gear-driven systems, they face constant pressure spikes, heat cycles, and contamination risks that can quickly shorten service life if fluid choice and maintenance are neglected. The right 20W-50 oil does

Horsepower is wasted without driveline strength: Every drag racer knows horsepower is useless if it doesn’t reach the ground. Differential failures, chewed-up gears, and lost passes don’t happen because the engine quit — they happen because the lubricant film broke down under shock loads. Gear oil is the last line of defense between winning torque
