Abstract
The present invention is generally directed to the present invention provides for multi-grade engine oil formulations comprising a diester component, wherein the diester component comprises vicinal diester species, and wherein at least a portion of said diester component is bio-derived. Many such formulations of the present invention are expected to favorably compete with similar, existing formulations comprising synthetic esters, but such formulations are generally expected to meet or exceed such existing formulations in a number of areas including, but not limited to, economics, biodegradability, and/or toxicity.
