摘要: A lubricity additive soluble in paraffinic lubes is prepared by cosulfurizing a blend of 90 to 50 and preferably 88 to 70 parts by volume of lard oil having a free acid content of less than 0.5 wt. % and preferably less than 0.2 wt. % and a pour point of 35.degree.-40.degree. F. and an olefin containing 2 to 24 carbon atoms at from 365.degree. to 445.degree. F. for 20 minutes to 10 hours followed by blowing with a gas to remove hydrogen sulfide.
