Petronas Disrol 50 oils are a high performance multipurpose crankcase marine diesel engine oil designed primarily as system oil for large low speed crosshead marine engine in both marine or stationary applications. It is manufactured using the finest quality base oils and advanced additive system to provide excellent engine cleanliness, especially in the hottest parts of the piston of crosshead engines and in the crankcase area. They provide excellent high temperature thermal and oxidation stability, low volatility and superior wear and corrosion protection. 

Applications
  Recommended for the crankcase lubrication of slow speed crosshead marine engines operating in marine or stationary applications. Also suitable for the lubrication of stern tube, deck machinery and other ancillary equipments.

Customer Benefits
• Excellent thermal and oxidation stability that effectively combat oil degradation in areas such as piston undercrown especially for piston cooling and thus ensure long oil life and good oil consumption control.
• Excellent detergency / dispersancy additives system provide exceptional engine cleanliness by effectively controlling varnish, lacquer and other common engine deposits and reduces maintenance cost.
 • Optimum level of alkalinity reserve provide effective neutralization of acidic combustion products (which enter the crankcase due to leaks in the connecting rod seals) to protect bearings and metals components against corrosive wear.
• Separate easily from water to optimized removal of contaminated water and minimize additive depletion during centrifuge.
