  • BASE OIL BLEND UPGRADING PROCESS WITH A DIESTER BASE OIL TO YIELD IMPROVED COLD FLOW PROPERTIES AND LOW NOACK
    Publication number: 20140342960
    Abstract: The present invention is generally directed to diester-based base oils and base oil blends with improved cold flow properties and improved Noack. The diesters employed have a number a performance benefits in lubricant applications—among them: biodegradability, extreme temperature performance, oxidative stability, solubility for additives and deposit and sludge precursors, flash and fire points. However, ester usage in lubricants has been quite limited due to their high cost. We utilize new proprietary diesters, structurally different from traditional diesters, which are made from fatty acids and alpha olefins in simple processing steps, yet feature performance similar to more traditional lubricant esters.
    Type: Application

  • DIESTER-BASED ENGINE OIL FORMULATIONS WITH IMPROVED LOW NOACK AND COLD FLOW PROPERTIES
    Publication number: 20140342961
    Abstract: The present invention is generally directed to diester-based multi-grade engine oil formulations. The diesters employed have a number a performance benefits in lubricant applications—among them: biodegradability, extreme temperature performance, oxidative stability, solubility for additives and deposit and sludge precursors, flash and fire points. However, ester usage in lubricants has been quite limited due to their high cost.
