Abstract
Lubricating oils containing oil soluble hydroxyalkyl alkanoates have been found to reduce fuel consumption in an internal combustion engine.
Claims8
In a lubricating oil formulated for use in the crankcase of an internal combustion engine, the improvement of including in said formulated oil about 0.10% to 5.0% by weight of at least one hydroxyalkyl alkanoate of the formula:
- ##STR2## wherein R is alkyl containing from 4 to 28 carbon atoms, one of R' and R" is hydrogen and the other is alkanoyl containing 1 to 30 carbon atoms.
A method for reducing fuel consumption in an internal combustion engine by treating the moving surfaces thereof with a composition comprising a major amount of an oil of lubricating viscosity containing a fuel-reducing amount of at least one hydroxyalkyl alkanoate of the formula:
- ##STR3## wherein R is alkyl containing from 4 to 28 carbon atoms, and one of R' and R" is hydrogen and the other is alkanoyl of 1 to 30 carbon atoms.
