Auto Transmission Fluid Oil (ULV) > FORD MUSTANG > XT12-QU-LV > MOTORCRAFT BRAND

This is a high-quality Automatic Transmission Fluid (ATF) manufactured by MOTORCRAFT, the official replacement parts division for Ford vehicles. This fluid is formulated to meet the proprietary MERCON ULV (Ultra Low Viscosity) specification, which represents the cutting edge of fluid technology designed for maximum efficiency.

 
 
This fluid, identified by the part number XT-12-QU-LV, is mandatory for Ford's most modern transmissions, particularly the 10-speed automatic (10R80) found in vehicles like the Ford Mustang (from 2018 models onwards). The ULV fluid's extremely low viscosity is integral to the transmission's design for reduced parasitic losses and improved fuel economy.

 
 
Key benefits of using Genuine MERCON ULV fluid include:

✔ Extreme Fuel Efficiency: Ultra-low viscosity minimizes internal drag for maximum efficiency.

✔ Precise Shift Quality: Provides the stable friction characteristics needed for the complex operation of a 10-speed gearbox.

✔ Thermal Endurance: Maintains performance and protection under the high thermal loads of performance applications like the Mustang.

Caution: MERCON ULV is unique and NOT interchangeable with MERCON LV, MERCON V, or any other fluid. Using the incorrect fluid will compromise shifting performance and cause severe damage to the 10-speed transmission.

 
 
Compatible Vehicle:

✔ Ford Mustang (equipped with 10-Speed Automatic Transmission requiring MERCON ULV)

✔ Other Ford/Lincoln vehicles equipped with the 10R series automatic transmission (requiring ULV).
