Piston Power MOSP 20W-50 is a  top quality universal engine oils 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 MOSP 20W-50 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.
