Petronas Disrol 300 oils are a premium quality cylinder and crankcase oils designed for  use in highly rated medium-speed trunk piston diesel engines (marine or stationary serv ice) burning high sulfur residual fuels under the most severe operating conditions.  It is manufactured using the finest quality base oils and advanced additive system to  provide outstanding residual fuel compatibility characteristics for excellent engine  cleanliness, especially in crankcase and camshaft areas. They provide excellent high  temperature oxidation and thermal stability, low volatility, load carrying properties and  corrosion protection.

Applications
Recommended for use in medium-speed trunk piston  engines burning high sulfur residual fuels, where  system and engine operational condition require  excellent cleanliness control especially to overcome  the “black sludge” and its associated problems. It is  also suitable for the lubrication of most reduction  gears used with medium speed engines.  

Customer Benefits
· High TBN value (32) and superior alkalinity  retention characteristics ensure excellent  protection in neutralizing the strong acids  resulting from the use of high sulfur fuels that  find access to the crankcase to promote oil  degradation, ring, cylinder and bearing corrosion.  
· Superior detergency / dispersancy additives  system provide exceptional engine cleanliness in  both hot and cold parts of the engine by  effectively controlling “black sludge”, lacquer and  other common engine deposits and reduces
maintenance cost.
· Excellent high temperature deposits control in  areas such as piston undercrown and piston ring  belt area enabling piston rings to function  efficiently to maintains high power output and  engine efficiency.
