  • Patent number: 4261841
    Abstract: A lubricating composition comprising a hydrogenated oligomer of a 1,3-diolefin, e.g., 1,3-butadiene, and a calcium petroleum sulfonate which can be at least one of a substantially neutral calcium petroleum sulfonate and an overbased calcium petroleum sulfonate is disclosed. The incorporation of the calcium petroleum sulfonate yields a composition having an unexpectedly, considerably lower pour point than that possessed by the hydrogenated oligomer alone.
