"Q. What is the difference between Molybdenum Disulfide (MoS2) and Teflon (PTFE) in terms of Solid Lubricants? A. Both materials are very slippery. Molybdenum Disulfide, or Moly, is a naturally occurring inert mineralization that will sustain loads in excess of 400,000 psi, while PTFE, a manufactured chemical, can only sustain loads in the 350 to 450 psi range. MoS2 remains effective up to its melting point exceeding 2,000°F while PTFE forms a noxious gas near 650°F. Some of this gas will invariably bypass the rings. Additionally, PTFE particle size is inconsistent and generally too large to remain in suspension in the oil. PTFE tends to “ball-up” or congeal at high temperatures, creating the possibility of plugging oil passages or pick-up screens."
Wouldn't the oil filter catch the particles before they could be distributed throughout the engine?
After what happened with Arco graphite, I would seriously think really hard before putting anything in powder form into an engine.
For anybody not familiar with Arco graphite, it used graphite since it both handles high temperatures and is an excellent lubricant.
The problem came about when the graphite settled and clogged passage ways in the engine. That's why I'm so leery about any powdered substance being added to engine oil. I really can't see how that stuff can work and not have similar problems with clogging oil ports and the filter.
