The correlation ηТ1,2 = соnst/Т has been refined. The viscosity ν = η/ρ in these oils is exponentially proportional to the concentration of asphaltenes+resins.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>релаксация</kwd><kwd>вязкость</kwd><kwd>концентрация асфальтенов</kwd><kwd>корреляция ηТ1</kwd><kwd>2 = соnst/Т</kwd></kwd-group><kwd-group xml:lang="en"><kwd>relaxation</kwd><kwd>viscosity</kwd><kwd>concentration of asphaltenes</kwd><kwd>correlation ηТ1</kwd><kwd>2 = соnst/Т</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">ГОСТ 8.615-2005 “Государственная система обеспечения единства измерений.
