Motorcraft Gear Oil

Motorcraft Gear Oil: Ford-Engineered Protection for Differentials and Transmissions

When it comes to protecting the drivetrain components in a Ford or Lincoln vehicle, few choices carry more weight than sticking with the brand that engineered the vehicle in the first place. Motorcraft — Ford Motor Company's own auto parts brand — brings that same factory-level precision to its line of gear oils, offering lubricants that are specifically developed to meet Ford's stringent in-house material specifications rather than generic industry standards.

A Range Built Around Ford's Own Specs

Motorcraft's gear oil lineup spans multiple viscosity grades and formulations to cover everything from classic rear-axle differentials to modern Super Duty drivetrain hardware. The SAE 80W-90 Premium Hypoid Rear Axle Lubricant is an excellent multi-purpose extreme pressure lubricant recommended by Ford Motor Company and meets warranty requirements. For owners of newer trucks running Dana heavy-duty axles, the Motorcraft 75W-140 Gear Oil meets Ford's stringent WSL-M2C192-A specifications and is designed for Dana M275 & M300 differentials.

At the synthetic end of the spectrum, Motorcraft's SAE 75W-140 Synthetic Rear Axle Lubricant is an excellent multi-purpose extreme pressure lubricant recommended by Ford Motor Company and is suitable for conventional and limited-slip differentials of passenger cars, light trucks, vans and buses operating under mild to severe service conditions. Manufactured using high-quality synthetic base oils and performance additives, it provides improved high-temperature thermal and oxidative stability, enhanced wear protection for hypoid gears, excellent shear stability, and protects from rust and corrosion.

For vehicles with front or rear axles calling for a lower-viscosity synthetic, Motorcraft's SAE 75W-85 Premium Synthetic Hypoid Gear Lubricant is an excellent multi-purpose extreme pressure lubricant recommended by Ford Motor Company for conventional and limited-slip differentials of vehicles which specify a fluid meeting WSS-M2C942-A. This product has been formulated to improve fuel economy and helps reduce operating temperatures.

Manual Transmission Coverage

Motorcraft gear oil isn't limited to axle applications. The brand also produces a dedicated manual transmission fluid in the gear oil family. Motorcraft Full Synthetic Manual Transmission Fluid is a premium-quality SAE 75W-90 gear oil recommended by Ford Motor Company and meets warranty requirements. It is particularly recommended for IB5 and 1995–2011 MTX-75 transmissions, and is manufactured with synthetic base oils and performance additives providing improved gear shifting at all ambient temperatures — with wear protection that extends the life of synchronizers and bearings. Due to its excellent thermal, oxidative, and shear stability, this fluid meets Ford's fill-for-life requirements.

Why OE Specification Matters

Motorcraft gear oil products meet all fill-for-life requirements of Ford Motor Company — a benchmark that generic lubricants rarely achieve. Using the correct Ford-specification fluid isn't just about performance; it's about maintaining factory warranty coverage and ensuring that limited-slip clutch packs, hypoid gears, and synchronizer rings are protected exactly as the engineers who designed them intended. Every Motorcraft component undergoes extensive testing beyond industry standards, simulating extreme conditions from Arctic cold to desert heat.
