Method for improving fuel economy of internal combustion engines using borated 1. 2-alkanediols
This patent describes a method for reducing the fuel consumption of an internal combustion engine by treating the moving surfaces with a compound consisting of: (a) a major amount of oil of lubricating viscosity; and (b) an amount of each of the following: (1) about 1 to 20% by weight of an alkenyl succinimide or alkenyl succinate or mixtures thereof, (2) about 0.1 to 4% by weight of a Group II metal salt of a dihydrocarbyl dithiophosphoric acid, (3) about 0.3 to 10% by weight of a neutral or overbased alkali or alkaline earth metal hydrocarbyl sulfonate or mixtures thereof, (4) about 0.2 to 27% by weight of a neutral or overbased alkali or alkaline earth metal, alkylated phenate, or mixtures thereof, (5) about 0.1 to 5% by weight of a mixture of a borated long-chain 1,2-alkane diol friction modifier.
