Additive concentrates and lubricant compositions containing a combination of additives which result in enhanced performance particularly as regards extreme pressure and antiwear performance. The combination of additives so utilized comprise a-1) at least one oil-soluble additive composition formed by heating concurrently or in any sequence at least one ashless dispersant which contains basic nitrogen and/or at least one hydroxyl group with (i) at least one inorganic phosphorus acid or anhydride, or at least one partial or total sulfur analog thereof, or any combination of the foregoing, and (ii) at least one boron compound; such that a liquid composition is formed; or a-2) at least one oil-soluble boron-free additive composition formed by heating (i) at least one boron-free oil-soluble ashless dispersant containing basic nitrogen and/or at least one hydroxyl group, with (ii) at least one inorganic phosphorus acid such that a liquid boron-free phosphorus-containing composition is formed; or a-3) one or more oil-soluble additive compositions formed by heating concurrently or in any sequence at least one ashless dispersant which contains basic nitrogen and/or at least one hydroxyl group with (i) at least one water-hydrolyzable organic phosphorus compound and water; and (ii) at least one boron compound; such that a liquid phosphorus- and boron-containing composition is formed; or a-4) one or more oil-soluble boron- free additive compositions formed by heating concurrently or in any sequence (i) at least one boron-free oil-soluble ashless dispersant which contains basic nitrogen and/or at least one hydroxyl group, with (ii) -at least one water-hydrolyzable organic phosphorus compound and water; such that a liquid boron-free phosphorus-containing composition is formed; and b) at least one oil-soluble metal-free sulfur-containing antiwear and/or extreme pressure agent having a sulfur content of at least 20% by weight; components a- 1), a- 2), a-3) or a-4) and b) being proportioned such that the mass ratio (wt:wt) of sulfur in component b) to phosphorus in component a-1), a-2), a-3) or a-4) is in the range of 8:1 to 30:1.
