Description

Sharlu Ace 5W-40, SN is a premium, full-synthetic motor oil specifically developed for high-performance gasoline engines. It maintains an unbreakable oil film under extreme mechanical shear and elevated operating temperatures. This 5W-40 grade provides the robust protection for engines operating in high-demand conditions.

Main Benefits

  • Advanced Oxidation Stability: Engineered to resist thermal breakdown and oil thickening, ensuring reliable lubrication and flow during grueling stop-and-go city driving. 
  • Enhanced Seal Integrity: Formulated with advanced base chemistry to maintain the elasticity of engine seals, effectively reducing the risk of oil leaks in both new and high-mileage vehicles.  
  • High-Temperature Deposit Control: Provides superior protection against sludge and varnish buildup, specifically designed to safeguard turbocharger components and multi-valve pistons from high-heat deposits.
  • Catalytic System Protection: Features a balanced chemistry that minimizes “catalyst poisoning,” ensuring the long-term efficiency and service life of the vehicle’s emission control system.

Application

  • Application: Sharlu Ace 5W-40, SN is recommended for powerful, modern gasoline engines, including multi-valve, fuel-injected, and turbocharged units in passenger cars, and performance SUVs where an API SN or earlier specification is required. Ideal for vehicles operating in diverse climates, providing instant flow during cold starts and superior stability in hot climates.
