To a mixture of 40 g of methanol, 30 g of octanol and 280 g of process oil (PUREXX12 : Esso Petroleum) was added 111 g of calcium hydroxide gradually to disperse it, 86 g of oleic acid was added, the mixture was stirred for 30 minutes, and carbon dioxide (20 L/hour) was blown thereinto at 50° C. for 6 hours to progress reaction. The mixture was gradually warmed to 160° C. to continue reaction while the formed water and the alcohol were distilled off, and then filtered to give a brown solution of an overbased calcium oleate-carbonate complex (Ca content=6.9% by weight; metal ratio=5.2) (this product is designated S-1).
