Piston Power MOS 20W-50 is a  top quality universal engine oil which provide superior lubrication in a wide range of petrol engines and high speed turbo-charged diesel engines as well as naturally aspirated diesel engines.


  • Naturally-aspirated and turbocharged gasoline four-stroke engines
  • Naturally-aspirated and turbocharged four-stroke, heavy-duty diesel engines in the road transport and construction industries and agricultural plant.

Performance Features

  • Outstanding thermal stability and oxidation resistance
    Outstanding thermal stability and oil oxidation resistance to maintain a high standard of piston cleanliness.
  • Cleaner engines
    Overall engine cleanliness contributes to low engine wear, long component life, maintenance of power output, more operational stability and lower servicing costs.
  • Excellent dispersancy
    Excellent dispersancy substantially reduces the risk of hot and cold sludge forming in the sump reservoir and under rocker box covers.
  • High temperature stability
    The high temperature stability of Piston Power Motor Oil Super is an outstanding feature. Carbon and lacquer deposits on vital moving parts, caused by very high engine temperatures, are effectively controlled by advanced functional additives.
