Abstract (en)
[origin: EP0542111A2] The invention relates to motor oils with high dispersing capacity, both single-grade and multigrade oils based on known, commercially available SAE viscosity class lubricating oil compositions; this is achieved in such a way that 0.5 to 2% by weight of a polyalkyl (meth)acrylate, which is a copolymer of 80 to 99.5 parts by weight of a C6- to C24-alkyl (meth)acrylate and 0.5 to 20 parts by weight of a C2- to C6-hydroxyalkyl (meth)acrylate and/or of a polyalkoxy(ether)ester of (meth)acrylic acid having a molecular weight of from 5,000 to 250,000 g/mol, is also added to the conventional formulations.
