Phillips 66® Gear Lube is a multipurpose, API GL-5 automotive gear lubricant specifically designed for use in passenger car and truck axles with hypoid gear sets. It also is recommended for use in some heavy-duty manual transmissions in trucks and buses.
(1) Note: For complete drain and refill, many limited-slip differentials may require the manufacturer’s specified gear lubricant or supplemental additive. Refer to the owner’s manual for specific requirements.
