Phillips 66® MP Gear Lube 80W-90

Phillips 66® MP Gear Lube 80W-90 is a high-quality, multipurpose gear lube 80w90 formulated to deliver dependable protection and performance in a wide range of automotive and heavy-duty applications. Designed to meet API GL-5 and MT-1 requirements, this lubricant supports reliable operation in axles, differentials, and selected manual transmissions operating under demanding conditions.

Reliable Protection for Hypoid Gears and Axles

Because MP Gear Lube 80W-90 is engineered for hypoid gear sets, it provides excellent extreme-pressure protection where sliding contact and high loads are present. As a result, it helps prevent scuffing, wear, and surface fatigue that can shorten component life. In addition, its high load-carrying capacity ensures consistent lubrication under varying speeds, loads, and torque conditions. Therefore, gears remain protected even during severe service.

Oxidation Resistance and Thermal Stability

This gear lube 80w90 offers excellent oxidation resistance and thermal stability, which helps minimize sludge and varnish formation. Consequently, it maintains cleaner gear housings and supports extended equipment reliability. Moreover, its thermal durability allows the lubricant to perform consistently across a wide operating temperature range.

Versatile Applications Across Multiple Equipment Types

Phillips 66 MP Gear Lube 80W-90 is recommended for service fill of conventional differentials in passenger cars and trucks. It is also suitable for top-off applications in limited-slip differentials in passenger cars and light trucks. Additionally, this lubricant supports use in differentials, final drives, and transfer cases found in select off-highway equipment.

Compatibility with Manual Transmissions

This gear lube 80w90 is also approved for use in non-synchronized manual transmissions in trucks, buses, and heavy equipment where the manufacturer specifies an API GL-5 or MT-1 gear oil. Because of its balanced formulation, it delivers reliable protection without compromising component performance.

Dependable Performance and Equipment Protection

MP Gear Lube 80W-90 protects against rust and corrosion, helping safeguard internal components during both operation and storage. At the same time, good foam resistance ensures consistent lubrication and helps prevent air entrainment under high-speed conditions. Because it combines proven additive chemistry with dependable base oils, it delivers long-lasting performance you can trust.

When applications call for a dependable gear lube 80w90, Phillips 66 MP Gear Lube 80W-90 provides proven protection, versatility, and value across automotive and heavy-duty environments.
