Lubricants containing metal salts of hydrocarbyl-substituted carboxyal- kylene-linked phenols, dihydrocarbyl esters of alkylene dicarboxylic acids, the alkylene group being substituted with a hydroxy group and an additional car- boxylic acid group, or alkylene-linked polyaromatic molecules, the aromatic moieties whereof comprise at least one hydrocarbyl-substituted phenol and at least one carboxy phenol, where the hydrocarbyl groups are of sufficient length to provide oil solubility to the salt, exhibit good asphaltene suspension for ma- rine diesel applications. Preferably the salts are overbased.
