Claims
- 1. A diesel crankcase lubricant composition comprising a diesel lubricating oil and from about 0.25 to 2.0 weight percent of the reaction product of a hydrocarbyl succinic anhydride in which the hydrocarbyl radical has from about 12 to 30 carbon atoms and 5-aminotriazole, said reaction product being prepared by reacting from 0.75 to 1.25 moles of said 5-aminotriazole with a mole of said hydrocarbyl succinic anhydride at a temperature ranging from room temperature to about 150.degree. C.
- 2. A composition according to claim 1 wherein the hydrocarbyl succinic anhydride has the formula ##STR3## wherein R is a monovalent aliphatic hydrocarbon radical having from about 12 to 30 carbon atoms.
- 3. A composition according to claim 1 wherein the reaction product has the formula ##STR4##
- 4. A composition according to claim 3 wherein the reaction product is a mixture of compounds having the formulae set forth in claim 3.
- 5. A composition according to claim 1 wherein said reaction product is present in an amount of between 0.5 and 1.5 weight percent.
- 6. A composition according to claim 5 wherein there is at least 0.75 percent by weight of said reaction product.
- 7. A composition according to claim 6 wherein said reaction product is present in an amount of at least 1 percent by weight.
- 8. A composition according to claim 1 wherein said reaction product comprises a product of the formula ##STR5## or a mixture thereof and said reaction product is present in an amount of 0.25 to 2.0 weight percent.
- 9. A composition according to claim 8 wherein said compound is present in an amount of at least 1 percent by weight.
