  • Method of lubricating a crosshead engine
    Patent number: 8377857
    Abstract: A method of lubricating a cylinder liner and a crankcase in a marine diesel crosshead engine with the same lubricating oil composition. The lubricating oil composition has a TBN, as measured using ASTM D 2896-98, of 10 to 55 mg KOH/g. The lubricating oil composition comprises: at least 40 mass % of an oil of lubricating viscosity; at least one detergent; at least one dispersant; and at least one anti-wear additive.

  • Lubricating Oil Compositions
    Publication number: 20080255013
    Abstract: Use of an oil-soluble hydrocarbyl phenol aldehyde condensate as an antiwear additive in a lubricating oil composition. The oil-soluble hydrocarbyl phenol aldehyde condensate has the following structure: wherein n is 0 to 10, preferably 1 to 8, more preferably 2 to 6, and most preferably 3 to 5; Y is a divalent bridging group, and is preferably a hydrocarbyl group, preferably having from 1 to 4 carbon atoms; and R is a hydrocarbyl group having from 4 to 30, preferably 8 to 18, and most preferably 9 to 15 carbon atoms.

  • Lubricating Oil Composition
    Publication number: 20080070818
    Abstract: A lubricating oil composition including at least one sulphurized overbased metal phenate detergent prepared from a C9-C15 alkyl phenol, at least one sulphurizing agent, at least one metal and at least one overbasing agent. The detergent includes less than 6.0% by combined mass of unsulphurized C9-C15 alkyl phenol and its unsulphurized metal salt. The lubricating oil composition exhibits an improved rate of acid neutralization.

  • Low phosphorus lubricating oil composition
    Publication number: 20040106527
    Abstract: This invention relates to a lubricating oil composition used in conjunction with a gasoline fuel having a sulphur content of less than 10 ppm by weight, characterised in that said oil composition has a phosphorus content of no more than 0.05% by weight. The feature of the invention is that the use of a low sulphur fuel enables the amount of anti-wear agents containing phosphorus such as eg ZDDP to be halved without any adverse effect on the anti-wear performance of the lubricating oil.
