Patented Dec. 22, 1931 UNITED STATES PATENT OFFICE WILLIAM ECG-ILL, OF WRITING, INDIANA, ASSIGNOR 1'0 COMPANY,
' OI 'WH'ITING, INDIANA, A CORPORATION OF INDIANA.
LUBRICANT OIL In accordance with the present invention the cold test, pour test or equivalent inspection test of viscous hydrocarbon oils such as those used primarily for lubricating pur poses is lowered by the addition to such oils of compounds ofhydroxystearic acid from the group including hydroxystearic acid, zinc hydroxystearate and magnesium hydroxystearatb. The proportion of the hy-' droxystearic acid compound supplied is controlled in proportion to the lowering in cold or pour test desired. Ordinarily the amount rzquilred is less than 40 to grams per liter o 01 I For eziample, with a viscous hydrocarbon lubricant oil of 180 .sec. ,Saybolt (100 F.) viscosity having a pour test of 30 to 35 F., the addition of 5 grams of hydroxystearic acid or zinc hydroxystearate reduces the pour test to below 10 F. The addition of 10 grams hydroxystearic acid per liter of oil reduces the pour test to 2? R; the addition of 10 grams magnesium hydroxystearate per liter of oil reduces the cold test to 5 F. and somewhat greater reductions. in cold tests were secured by the addition of larger amounts of the hydroxystearic' acid compounds.
