<p>A function fluid, such as a lubricating oil, has improved anti-wear properties by the presence therein of one or more substituted compounds, being substituted pyridines, pyrimidines, pyrazines, pyridazines and/or fused ring derivatives thereof. Examples of such compounds are 2-(aminomethyl) pyridine, 3-chloropyridine, 4,4'-dithiodipyridine, 5-bromopyrimidine, 3-chloro-2,5-dimethylpyrazine, 3-4-5-trichlorpyridazine and 6-methoxyquinoline.</p> |
