Lubricating oil compositions containing methylol polyether amino ethanes

摘要

Additives for lubricating oils for internal combustion engines which contribute dispersancy and detergency to the lubricating oils are disclosed. The additives are hydrocarbyl methylol poly(oxyalkylene) amino ethanes comprising a hydrocarbyl-terminated methylol poly(oxyalkylene) chain of 2 to 4 carbon oxyalkylene units bonded to an ethane or substituted ethane chain in turn bonded to a nitrogen atom of an amine or polyamine having from 1 to 12 amine nitrogens and from 2 to 40 carbon atoms.
