Molybdenum Disulfide (moly) what is your experience for Wheel Bearing Grease?

Molybdenum Disulfide
Can it be used for wheel bearings? Says Ford uses it for some bearings, a youtuber was using it
Here is what I found on the web:
In Performance Extremely High Temperatures
Moly grease is known for its excellent performance in high temperature environments. However, there are limits to its capabilities. In extremely high temperatures exceeding 400°F (204°C), moly grease can break down and lose its lubricating properties. At these extreme temperatures, it is recommended to use a specialized high-temperature grease specifically formulated for such conditions. These greases often contain synthetic additives that can withstand the extreme heat without compromising performance.
High-Speed Bearings
While moly grease is excellent for many types of bearings, it may not be suitable for high-speed applications. At high speeds, the molybdenum disulfide particles in the grease can become dislodged and act as abrasive particles, leading to increased friction and excessive wear on the bearing surfaces. In such cases, it is advisable to use a lighter, non-moly grease or a specialized high-speed bearing lubricant
My Verdict: Probably OK but going with High Temperature Grease

A 30" tire at 60mph is spinning at about 674 RPM. Not exactly high speed.
