[bruker]

What's the correct rear diff fluid for a 2020 Edge and where did you get it from? Thanks

The Owner's Manual?  That's a funny place to look.   😉

 

That particular option is ridiculously / outrageously expensive.  This is what I use :  Redline MT-LV 70W/75W  ( Full Synthetic )

The Motorcraft oil is specifically made(formulated) for the Ford "Disconnect Rear Drive Unit". Hence assume it is not a general gear oil like other makes. The Motorcraft specs (link) states:

 

• Motorcraft® SAE 75W Disconnect Rear Drive Unit Fluid is specifically formulated for Ford disconnect rear drive units with a low offset hypoid gear
• Developed with a lower viscosity to improve axle efficiency and fuel economy
• Motorcraft® SAE 75W Disconnect Rear Drive Unit Fluid is formulated with synthetic base stocks, friction modifiers, antiwear and extreme pressure additives to provide gear protection and smooth clutch operation
• Use only in Ford Disconnect Rear Drive Units
• DO NOT use in conventional high-offset hypoid gear axles where SAE 75W-85, 75W-90, 80W-90 or 75W-140 is recommended

Good repeat of the manufacturer's position.  It really means nothing.

As long as someone uses an oil, gear oil, etc., that, at a minimum, meets the standards of the specified oil, gear oil, etc., then said oil performs the same, at a minimum, of the specified oil.

 

Redline MT-LV 70W/75W  ( Full Synthetic ) meets that specification.
