  • Patent number: 8618029
    Abstract: The present invention provides overbased detergents as lubricating oil additives effective for the lubrication of mechanical components in land and marine engines, such as, for example, hydraulic systems, transmissions, two-stroke and four-stroke vehicular engines, trunk piston and two-stroke crosshead marine engines. These overbased detergents lead to improved detergency and thermal stability performances versus high overbased sulfonates. Moreover, they are more compatible with commercial phenates than conventional sulfonates.
