Urania Optimo 10W-40

Extra High Performance Synthetic Blend Diesel Engine Oil exceeding MB 228.5 Performance Levels
PETRONAS Urania Optimo 10W-40 is an extra high performance synthetic blend diesel engine oil engineered specifically to meet the challenge of the most severe lubrication requirements of the latest European heavy duty diesel engines by providing outstanding lubrication for engines running under the extreme demands of significantly reduced regulatory emission parameters and extended oil change intervals.
It is formulated from highest quality base stocks and advanced performance additives which provide excellent low temperature fluidity, excellent thermal stability, low volatility, consistently efficient long life performance and excellent protection to all parts of the engines.
Customer Benefits
  • Excellent anti-wear and anti-scuff properties to prolong engine life
  • Exceptional thermal and oxidation stability for outstanding protection against oil thickening, high temperature deposits, sludge build-up and oil degradation
  • Exceptional soot dispersancy, preventing deposits on critical engine components and provide excellent protection from soot induced wear
  • Excellent TBN retention for exceptional long drain capabilities and long term deposit and wear control
  • Stay in grade shear stability and low volatility reduce viscosity breakdown and oil consumption under high temperature operating conditions
  • Optimum formulation viscometrics (high temperature high shear viscosity) to reduce engine scuffing and reduce bore polishing
