    摘要: A method for preventing or reducing engine knock or pre-ignition in a high compression spark ignition engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition that contains (i) a lubricating oil base stock comprising at least one branched ester having at least about 15% of the total carbons in the form of methyl groups, and (ii) at least one ashless antiwear additive selected from a phosphorus-containing ashless antiwear additive, a sulfur-containing ashless antiwear additive, and a phosphorus/sulfur-containing ashless antiwear additive. A lubricating engine oil having a composition that contains (i) a lubricating oil base stock comprising at least one branched ester having at least about 15% of the total carbons in the form of methyl groups, and (ii) at least one ashless antiwear additive selected from a phosphorus-containing ashless antiwear additive, a sulfur-containing ashless antiwear additive, and a phosphorus/sulfur-containing ashless antiwear additive. The lubricating oils of this disclosure are useful as passenger vehicle engine oil (PVEO) products.

    摘要: An overbased calcium sulfonate grease composition comprising a reduced amount of overbased calcium sulfonate, calcium hydroxyapatite, base oil, one or more converting agents, and one or more complexing acids if a complex grease is desired. The calcium sulfonate grease composition improves thickener yield and expected high temperature utility as demonstrated by dropping point. A method of making the composition comprising the steps of mixing the calcium sulfonate and base oil, adding the calcium carbonate either before or after conversion, adding one or more converting agents, and adding one or more complexing acids. All or a portion of one or more of the complexing acids may be added with or prior to the one or more converting agents.
