Ford Motorcraft MERCON V Automatic Transmission & Power Steering Fluid — 5 Quart, Red-Dyed, Thermal Protection

Ford Genuine Motorcraft MERCON V is a red-dyed, factory-recommended automatic transmission and power steering fluid formulated to deliver smooth shifting, thermal protection, and corrosion resistance for Ford, Lincoln and Mercury vehicles that call for MERCON V or MERCON ATF.

If you own a vehicle that specifies MERCON V or MERCON type fluid, choosing the Ford Genuine Motorcraft formulation ensures compatibility with factory seals and valve bodies while providing dependable low-temperature flow and high-temperature stability. This 5-quart container is convenient for top-ups, partial service, or for technicians performing transmission and steering system maintenance. The formula uses high-viscosity-index base oils and refined additives designed to resist oxidation, reduce foam, and help prevent deposits that can impair component performance.

How does this fluid improve shifting performance?

Motorcraft MERCON V is engineered to maintain consistent frictional properties across a wide temperature range, which helps transmission clutches and bands engage predictably. Stable viscosity and anti-oxidant additives reduce the risk of sludge and varnish that can affect smooth gear changes over time.

• High-viscosity-index base oils for steady flow and pressure
• Additives that maintain friction characteristics for crisp shifts
• Oxidation inhibitors to limit varnish and deposit formation

Can I use it for power steering and other hydraulic applications?

Yes — this product is suitable for use in power steering systems that specify MERCON V or MERCON-type ATF. It also matches ISO 46 / SAE 20W viscosity grades, making it usable in certain industrial hydraulic applications that call for those specifications.

• Approved for Ford, Lincoln and Mercury power steering systems calling for MERCON V
• Compatible with hydraulic equipment requiring ISO 46 or SAE 20W viscosity
• Not recommended where MERCON SP, MERCON LV, Type-F, or CVT-specific fluids are required

What protections does Motorcraft MERCON V provide?

The formulation includes additives that guard against wear, corrosion, and foaming to prolong component life and system reliability. Thermal and oxidation resistance help preserve fluid integrity under prolonged use and high operating temperatures.

• Wear inhibitors to protect gears, clutches and pump components
• Rust and corrosion inhibitors for internal metal protection
• Anti-foam chemistry to maintain hydraulic responsiveness

Are there any important compatibility or usage cautions?

Use only in systems that specifically call for MERCON V or MERCON-type fluid; do not substitute where MERCON SP, MERCON LV, Motorcraft premium ATF, FNR5, Type-F, or CVT chain fluids are specified. Also avoid using it in transfer cases previously requiring MERCON ATF without confirming compatibility.

• Follow your vehicle owner’s manual for the correct fluid specification
• Do not mix with fluids that have incompatible additive chemistries
• Red dye aids leak detection but do not rely solely on color for verification

Who is this for: Ford Genuine Motorcraft MERCON V — 5 Quart is aimed at Ford, Lincoln and Mercury owners, independent mechanics, and fleet service shops needing a factory-recommended ATF/power steering fluid for vehicles that call for MERCON V or MERCON-type fluid. It’s a practical choice for routine maintenance, partial transmission service, and for operators who also want the flexibility to use the fluid in compatible industrial hydraulic equipment. Always confirm your vehicle’s required specification before purchase to ensure proper compatibility.
