Intro
PETRONAS Disrol 120 oils are premium quality cylinder and crankcase oils designed for use in  high, specific output medium-speed trunk piston diesel engines (marine or stationary service)  burning distillate fuels or light fuel blends with sulfur content up to 1.0% wt operating under severe operating conditions.
They are manufactured using the finest quality base oils and an advances additive system to  provide excellent engine cleanliness, especially in crankcase and camshaft areas. They provide  excellent high temperature oxidation and thermal stability, low volatility and superior wear and  corrosion protection.

Applications
Recommended for the lubrication of medium-speed trunk piston engines operating on distillate  fuels or light fuel blends. Also suitable for use as crankcase oil in large crosshead type diesel
engines operating on high sulphur fuels.
Customer Benefits
• Neutralisation value of 12 TBN and superior alkalinity retention characteristics of the oil  ensure excellent protection in neutralizing the strong acids resulting from the use of high  sulphur fuels that find access to the crankcase to promote oil degradation, ring, cylinder  and bearing corrosion.
• Superior detergency/dispersancy additive system provides exceptional engine  cleanliness by effectively controlling varnish, lacquer and other common engine deposits  to reduce maintenance cost.
• Excellent high temperature deposits control in areas such as piston undercrown and  piston ring belt areas enabling piston rings to function efficiently to maintain high power  output and engine efficiency.
• Separate easily from water to minimize additive depletion during centrifuge.
• Outstanding thermal and oxidation stability to ensure long oil life and possess good oil  consumption control.
