Object

There found a demand for ashless type novel lubricant which does not contain phosphorus, sulfur or metals and has high friction reducing effect, and suppresses the generation of deposit/sludge and the like, and furthermore can exhibit a detergency effect. It is an object to provide a novel lubricant capable of responding to this demand.

In addition, it was found out that it is required to demonstrate performances such as friction reduction effect and detergent effect under various low temperature and high temperature environments. In the present invention, it is also an object to provide a novel lubricant which can exhibit excellent performance even under various low temperature and high temperature environments even at the higher dosage.

Solution

A lubricating oil/grease additive characterized by containing a polyetheramine carboxylic acid salt represented by the general formula (1).

[R.sub.1COO.sup.][R.sub.2O(AO)m-X.sup.+](1)

Here, the carboxylic acid is a carboxylic acid having carbon number R.sub.1=7-21, preferably carboxylic acid having carbon number R.sub.1=7-19, more preferably oleic acid R.sub.1=C17.

R.sub.2 is a hydrocarbon group of carbon number from 8 to 50, A is an alkyl group of carbon number from 2 to 6, O is oxygen, m is an integer of 10 to 50, and X is an amino group or a substituted amino group.

Lubricant compositions comprising a lubricating oil and a mixture of one or more alkylated diarylamine and one or more alkylated hydroxydiarylamine exhibit excellent antioxidant and deposit control performance.
