Motor oil blend and method for reducing wear on steel and eliminating ZDDP in motor oils by modifying the plastic response of steel

A method, comprising:

• lubricating steel-on-steel sliding mechanisms and non-babbitt bearings of an engine, comprising:
• introducing into the engine a motor oil, said introducing comprising preventing ZDDP from the chemical constituents of the motor oil and preventing ZDTP from the chemical constituents of the motor oil;
• introducing into the engine in combination with said motor oil, a motor oil additive comprising polymerized alpha-olefins and hydroisomerized hydro-treated severe hydrocracked base oil, said introducing comprising preventing ZDDP from the chemical constituents of said motor oil additive and preventing ZDTP from the chemical constituents of said motor oil additive;
• the combination of said polymerized alpha-olefins and said base oil properly lubricating at least said steel-on-steel sliding mechanisms and non-babbitt bearings of said engine and favorably modifying a plastic response of at least such components thereby reducing engine wear;
• the motor oil blend of the motor oil and the motor oil additive containing no ZDDP and no ZDDP yet favorably modifies a plastic response of at least said steel-on-steel sliding mechanisms and non-babbitt bearings of said engine and thereby provides tribologically-measurably antiwear performance thereof comparable to motor oil compositions configure for such engines comprising ZDDP or containing ZDTP;
• and
• wherein said introducing said motor oil blend into the engine comprises lubricating at least said steel-on-steel sliding mechanisms and non-babbitt bearings of the engine while preventing the release of ZDDP and ZDTP from the engine into the environment during use of the engine.
