  • Publication number: 20110041797
    Abstract: A crankcase lubricating oil composition comprising: (A) an oil of lubricating viscosity in a major amount; (B) as an additive component in a minor amount, an oil-soluble metal salt of a dithiophosphoric acid; (C) as an additive component in a minor amount, an oil-soluble carbodiimide compound; and, wherein the lubricating oil composition is contaminated with at least 0.3 mass %, based on the total mass of the lubricating oil composition, of a biofuel or a decomposition product thereof and mixtures thereof.

  • Patent number: 6660695
    Abstract: A power transmission fluid comprising a mixture of a major amount of a lubricating oil and an effective amount of a performance enhancing additive combination comprising: (a) at least one organic phosphate having the structure R1—X2—P(:X1)(R2X3)—X—R5 where R1, and R2 may independently be substituted or unsubstituted alkyl, aryl, alkylaryl or cycloalkyl having 1 to 24 carbon atoms and X, X1, X2 and X3 may independently be sulfur or oxygen. R1 and R2 may also contain substituent hetero atoms, in addition to carbon and hydrogen, such as chlorine, sulfur, oxygen or nitrogen; wherein R5 is derived from a reactive olefin and can be either CH2—CHR—C(:O)O—R6; —CH2—CR7HR8; or R9—OC(:O)CH2—CH—C(:O)O—R10 where R is H or the same as R1, R6, R7, R9 and R10 are the same as R1 and R8 is a phenyl or alkyl or alkenyl substituted phenyl moiety, the moiety having from 6 to 30 carbon atoms, (b) a calcium detergent, and (c) a friction modifier.

  • Patent number: 6337309
    Abstract: A zinc-free lubricating composition for lubricating a continuously variable transmission is disclosed, the lubricating composition comprising a mixture of a major amount of a lubricating oil and an effective amount of a performance enhancing additive combination comprising: (a) an ashless polyisobutenyl succinimide dispersant; (b) at least one organic thioether phosphite; (c) a calcium phenate overbased detergent at a concentration such that the total amount of calcium in the fluid is less than about 500 ppm; (d) friction modifiers comprising one or more succinimides and one or more ethoxylated amines; and (e) a primary amide of a long chain carboxylic acid.
