Thats interesting. Some see black stuff settling down into Pennzoil (& others) bottles/jugs, so maybe its the moly particles.
It would be interesting if WS2 (tungsten compound) settles out of the LiquiMoly Molygen bottles/jugs. If it can set on a shelf for a month and not settle, then its not a problem.
When there are so many possible forms of moly compounds, its hard to tell if WS2 is worthwhile anymore. LiquiMoly makes some Molygen WS2 motor oil friction and wear claims, but they won't elaborate on them at all from what I've seen (too marketing-mysterious).
Member Trav has first hand experience with Lubro Moly MOS2 falling out of suspension in a vehicle that wasn't driven on a daily basis and posted pics I believe. That was proof enough for me to stop using it. If you're looking to boost moly and want to use a moly that will stay in suspension look at Lubegard Bio Tech Engine Protectant. They don't use MOS2, their moly doesn't settle out.
