Syngear SS

Premium Synthetic Automotive Gear Lubricant
Phillips 66®Syngear SS is a synthetic, multipurpose, API GL-5 automotive gear lubricant. It is specifically designed for use in passenger car and truck axles with hypoid gear sets operating in extreme temperatures or under severe driving conditions. It is formulated to provide long service life and extended gear life in automotive differentials operating under varying conditions of speed, load, temperature and torque. The carefully balanced formulation is designed to minimize oxidative sludge and varnish formation, reduce wear, prevent scoring damage, and protect against metal fatigue and spalling damage under shock-load conditions.

Features & Benefits

• Extended drain, all-season performance

• Outstanding oxidation resistance and thermal stability to minimize sludge and varnish formation

• Excellent thermal durability and extreme-pressure properties for extended gear life

• High load-carrying capacity for protection against scuffing and wear

• High shear stability

• Outstanding low-temperature properties

• Protects against rust and corrosion

• Good foam resistance

• Reduces axle operating temperatures compared with conventional mineral gear oils

Applications

• Service fill of conventional differentials, and top-off only of limited-slip differentials, in passenger cars and trucks

• Service fill of differentials, final drives and transfer cases in some off-highway equipment

• Non-synchronized manual transmissions in trucks, buses and heavy equipment where the manufacturer specifies an SAE 75W-140, API GL-5 or MT-1 gear oil
