PETRONAS DISROL 50
Premium Quality 6 TBN Marine Diesel Engine Oils
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 • Separate easily from water to optimized removal
speed crosshead marine engines operating in marine
