Abstract

This disclosure relates to cold cranking simulator viscosity ('CCSV') reducing base stocks that allow flexibility for low viscosity SAE engine oil grades (e.g., 5W and 0W) to meet demanding low temperature viscosity requirements while maintaining a higher base oil viscosity for improved wear protection. The CCSV-reducing base stocks include mono-esters derivable from a Guerbet alcohol and a monocarboxylic acid. The disclosure also relates to lubricating oils containing the CCSV-reducing base stocks, and a method for improving fuel efficiency and/or wear protection in an engine by using as the lubricating engine oil a formulated oil containing one or more of the CCSV-reducing base stocks.
