As to how you'd get it to adhere to combustion chamber, I have no clue.

A quick search points to it being a good solid lubricant:

And possibly soluble in fuel..?

ie: A possible fuel additive..?

All the above seem to work be true:

• Soluble.
• Solid Lubricant.
• CO2 to Syngas (H2 and CO which burns) catalyst.

Problem is I cant find any besides in expensive glass polish here.
Can this be found in the 1st world for a decent price by anyone?
