Document Type and Number:
Japanese Patent JP2598489
Kind Code:
B2
Abstract:
Overbased magnesium sulphonates having increased resistance to interactions are prepared from sulphonic acids prepared from alkylates with long and medium chain alkyl groups. Compositions comprising such overbased magnesium sulphonate are particularly suitable for use in combination with high molecular weight dispersants and/or friction modifiers. Stable sediment-free lubricating oil compositions (including lubricants and concentrates therefor) can be prepared which can meet SG quality and the Tier II fuel economy requirements.
