MO-525

Molybdenum dithiocarbamate (MoDTC), liquid

Liquid MoDTC — the friction modifier that fuel-economy engine oils are actually built on. Pre-diluted to 40 % oil for straightforward cold blending, which removes the handling problem that keeps blenders away from the solid grades.

The chemistry

Molybdenum Friction Modifiers

Friction reduction via in-situ MoS₂ tribofilm

Typical treat rate0.1 – 1.0 %

Organomolybdenum compounds decompose under load to deposit molybdenum disulphide in the contact. The measurable result is a lower boundary friction coefficient and a direct fuel-economy credit — which is why these carry the highest value density of anything in this catalogue and why they matter regardless of powertrain.
