Claims9
A lubricating composition comprising:
- a. an oil of a lubricating viscosity;
- b. 0.1 to 0.3 wt % of a thiadiazole comprises a hydrocarbyl substituted 2,5-dimercapto-1,3,4-thiadiazole;
- and
- c. 0.1 to 0.3 wt % of an azole-acrylic adduct represented by formula (VI):
- wherein R6 is CH3;
- R7 is attached to a nitrogen atom and is a linear C2 hydrocarbyl group;
- and R8 is a C24-C8 hydrocarbyl group and is linear, branched, homocyclic, heterocyclic, or a combination thereof;
- and
- wherein the aggregate amount of the thiadiazole and the azole-acrylic adduct is at least 0.3 wt %, based on a total weight of the lubricating composition.
