CALTEX DELO® GEAR EP-5 – EXTREME PRESSURE AUTOMOTIVE GEAR OIL

Product Introduction

• Delo® Gear EP-5 is a multipurpose automotive gear oil specially developed to protect automotive gear systems, differentials, and heavy-duty transmissions. The product is formulated with premium paraffinic base oils and a balanced additive system designed to protect gears against wear, scoring, and corrosion under all operating conditions. The sulfur-phosphorus extreme pressure additive technology used in Delo® Gear EP-5 provides outstanding thermal stability and oxidation resistance while forming a protective film on gear surfaces at high-pressure contact points, significantly reducing wear and surface fatigue.
• In addition to its extreme pressure performance, the product is fortified with anti-rust and anti-corrosion additives, anti-foam agents, and pour point depressants. This advanced formulation enables stable operation across a wide temperature range, maintains effective lubrication under severe conditions, and extends both lubricant and gear service life.

Key Features and Benefits

Delo® Gear EP-5 forms a thin protective lubricant film on gear surfaces to reduce friction and withstand high contact pressures. During operation, heat generated at gear contact points activates the sulfur-phosphorus additives, creating a durable protective layer that helps balance the service life of gears, bearings, and the lubricant itself. Its extreme pressure properties provide reliable protection for hypoid gears and spiral bevel gears, minimizing wear and scoring during operation.

• The anti-rust and corrosion inhibitor system protects metal components against oxidation and corrosion, even in humid environments or when exposed to corrosive elements. Anti-foam additives help minimize foam formation, ensuring smooth system operation and maintaining continuous lubrication performance. The product’s excellent thermal stability and oxidation resistance allow Delo® Gear EP-5 to maintain its chemical and physical stability, extending oil life even under continuous high-temperature and heavy-load conditions.
• Delo® Gear EP-5 is also specially formulated to protect seals and gaskets, reducing aging and oil leakage. This helps maintain the long-term operational stability and efficiency of transmissions, differentials, and wheel bearing steering systems.

Applications

Delo® Gear EP-5 is recommended for spiral bevel gears and hypoid gears used in differentials, manual transmissions, and wheel bearing steering systems. With its multigrade characteristics, the product performs effectively over a broad temperature range, ensuring good flow properties during cold starts while providing optimal gear protection at elevated operating temperatures. The product is suitable for long-haul vehicles, heavy-duty trucks, and differential systems operating continuously under severe working conditions where high mechanical durability and superior gear protection are required.

Performance Standards

Delo® Gear EP-5 is approved under SAE J2360 (formerly MIL-PRF-2105E) and meets the requirements of API GL-5, API MT-1, and Mack GO-J specifications. These approvals ensure compliance with the stringent technical requirements of most modern automotive differentials and transmission systems. The product has been tested and certified to provide outstanding gear protection performance under demanding operating conditions.
