Oil-soluble calcium sulfonates on the basis alkylnaphthalene obtained using propylene oligomers of the C₁₈–C₃₀ fraction have been obtained and characterized. The developed synthetic sulfonate additives with different alkalinity possess high physico-chemical and functional properties and are superior in performance to commercial oil sulfonates C-150 and C-300, as well as foreign analogues – additives OLOA-246B and Hightech 6060M. Using the obtained high-alkaline additive, an experimental motor oil M-10G₂ was developed, which meets the quality indices required demands
