COMPOSIZIONI ALCHIL-FENOLICHE E AMMINO-FENOLICHE, E OLI PER MOTORI ADUE TEMPI E COMBUSTIBILI CHE LE CON TENGONO

摘要

Additive combinations useful in lubricating compositions containing a major amount of an oil of lubricating viscosity are described. The additive compositions comprise a mixture of at least one alkyl phenol and at least one amino phenol, each having at least one hydrocarbon-based group of at least about 10 aliphatic carbon atoms. The additive compositions also are useful in fuel-lubricant mixtures for use in two-cycle internal combustion engines. Generally, the additive combinations also will contain a detergent/dispersant.
