AMSOIL Industrial Synthetic Low-Ash Natural Gas Engine Oil is engineered with premium synthetic base oils to deliver superior durability, longevity, viscosity control and all-season performance in stationary engines operating on gaseous fuels. It provides excellent resistance to oxidation, nitration and deposit formation to help keep components clean, reduce valve recession and extend turbocharger and emissions-system performance and life.

  • Resists oxidation to protect against deposit formation.
  • Fights carbon and varnish to keep components clean.
  • Superior extreme-temperature operability.
  • Excellent cold-crank viscosity in standby applications.
  • Low-ash (0.51%) formulation protects emissions systems.
  • Protects against damaging valve recession and engine wear.
