DETERGENT ADDITIVE-CONTAINING MINERAL OILS HAVING IMPROVED COLD FLOW PROPERTIES

摘要

The invention relates to the use of at least one oil-soluble olefin copol ymer B) which acts as a nucleating agent for paraffin crystallization for im proving the response of cold flow improvers for mineral oils C), which are d ifferent from B), in middle distillates that contain at least one ashless, n itrogenous detergent additive A), which is an oil-soluble, amphiphilic compo und that comprises at least one alkyl or alkenyl group bound to a polar grou p, said alkyl or alkenyl group having 10 to 500 C atoms and the polar group having 2 or more nitrogen atoms.
