<p>The present invention provides a lubricant additive composition which functions both as a friction reducing agent and as an extreme pressure additive, and also has the ability, when incorporated in a lubricant, to improve substantially the low temperature viscosity characteristics of the lubricant. The composition, in one form, comprises: (1) 35% by weight of 24% lead naphthenate solution in an organic solvent therefor; (2) 40% by weight of "Tellus 32 Oil"(Trademark), this being a blend of HVI 100 Neutral Oil with HVI 250 Neutral Oil; and (3) 25% by weight of desulfurized diesel oil. In a second, heavy-duty form, the composition comprises, about 5% to about 45% by weight of a lead soap of an organic acid, said lead soap being in the form of a solution in a liquid solvent therefor, said solution containing from 10%-32% by weight lead; 20%-50% by weight of an oil having a viscosity in the range of from about 45 SUS at 100.degree.F. to about 3000 SUS at 100.degree.F.; 5%-40% by weight of desulfurized diesel oil, or of a hydrocarbon oil having physical characteristics comparable to said diesel oil; 0.10%-5.00% by weight of an oil soluble zirconium-containing soap selected from the group consisting of zirconium naphthenate, zirconium 2-ethylhexanoate, zirconium 3,5-dimethyl hexanoate, and zirconium neodecanoate, or mixtures thereof, and 0.10%-5.00% by weight of calcium in an oil soluble form, as calcium naphthenate or calcium 2-ethylhexanoate; said composition functioning both as a friction reducing agent and as an extreme pressure additive.</p> |
