Yes, we have shown that TriboTEX works in diesel engines when used at about 3X the concentration as in gasoline engines. If you want the same effects in your diesel engine, apply 3X as much TriboTEX as you would for a gasoline engine.
This is because diesel engines have a much higher soot content and a higher compression ratio. This combination interferes with our nano material's ability to bind to the metal surfaces inside the diesel engine, so more is needed to effectively get the same results as those observed in gasoline engines.
We may be announcing a stretch goal for a special formulation for diesel engines in the next update...
