A high grade lubricant developed for high speed, four-stroke engines to meet 1998 exhaust emission standards. Formulated with advanced additive technology, it provides excellent all weather protection and controls the emissions in high speed engines.

Available API
CH-4
CH-4/SL
Applications

API CH-4 was developed for diesel engines without after-treatment emission systems. They can be used
with diesel fuels ranging in sulfur content up to 0.5% weight. API CH-4 approved oils are backward
compatible and are superior in performance to API CF-4, CF, CE, CD oils. Can be used in all land based
diesel engines including:

  • Diesel powered large trucks, buses and construction machinery.
  • Light duty diesel cars, vans and buses.
  • Naturally aspirated and turbocharged diesel engines
Features & Benefits
  • High thermal and oxidation stability.
  • Proven metallo-organic anti-wear additive system protects engines under all operating conditions.
  • Excellent soot handling capability allowing for extended drain interval.
  • Optimum performance over a wide range of operating conditions.
  • Very good detergency and dispersancy ability to keep the engine clean and efficient control of sludge
    and soot deposits.
