FORMULATED LUBRICANTS MEETING 0W AND 5W LOW TEMPERATURE PERFORMANCE SPECIFICATIONS MADE FROM A MIXTURE OF BASE STOCKS OBTAINED BY DIFFERENT FINAL WAX PROCESSING ROUTES

摘要

Formulated lubricating oils meeting OW and 5 W low temperature CCS and MRV performance specification and exhibiting a Noack volatility of about 15 wt% or less are prepared from a mixture of base stocks/base oils of similar kinematic viscosity grade range produced by different final wax processing routes and omitting or reducing the amount of viscosity modifiers and pour point depressants.
