The physical package ships as a single unit with compact dimensions and lightweight handling for easy storage and handling.

What does Motorcraft Rear Axle Oil XY75W85QL do for my vehicle?

This lubricant reduces metal-to-metal contact in the rear differential to lower wear and help maintain smooth gear operation. It provides a stable film between gears and bearings so components run cooler and last longer when used in appropriate applications.

• Designed for rear axle assemblies and differential units
• Stable viscosity for consistent lubrication under load
• Helps minimize friction and surface wear on gears

How do I use and store this axle oil safely?

UseMotorcraft XY75W85QL during scheduled differential service or when topping off according to the vehicle manufacturer’s recommendations. Store the sealed container upright in a cool, dry place away from direct sunlight and heat sources.
