Abstract: A method for improving wear control in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition that includes a lubricating oil base stock as a major component; and at least one phosphazene represented by the formula as a minor component. In the above formula, Q is nitrogen, sulfur or oxygen; a is a value from about 2 to about 6, c is a value from about 2 to about 6, e is a value from about 2 to about 6, g is a value from about 2 to about 6, i is a value from about 2 to about 6, and k is a value from about 2 to about 6; b is a value of 2a+q, d is a value of 2c+r, f is a value of 2e+s, h is a value of 2g+t, j is a value of 2i+u, and l is a value of 2k+v; q, r, s, t, u and v are independently a value of 0 or −2; with the proviso that not all of a, c, e, g, i and k are the same value. A lubricating oil having a composition that includes a lubricating oil base stock as a major component; and at least one phosphazene represented by the above formula as a minor component. The lubricating oil is useful in internal combustion engines.
