It uses a sulfur‑phosphorus extreme‑pressure additive package to protect gears under high loads while resisting foaming, rust, and corrosion. This oil is typically drained and refilled at manufacturer‑recommended service intervals (often 100,000–250,000 miles for heavy‑truck axles) to prevent wear and costly gear‑failure repairs.
