Synthetic Stationary Natural Gas Engine Oil


AMSOIL Synthetic Stationary Natural Gas Engine Oil delivers superior protection in stationary natural gas engines calling for an SAE 40, low-ash lubricant. Its shear-stable formula qualifies it as a multi-grade 20W-40 so it can be used over a broad ambient temperature range, reducing the need for seasonal oil changes.


See the Product Data Bulletin for full details.

Available In:
  • 5 Gallon Pail
  • 55 Gallon Drum
  • 275 Gallon Tote

Formulated to Provide Top Efficiency in Stationary Engines Fueled by Natural Gas

  • AMSOIL Synthetic Stationary Natural Gas Engine Oil is formulated with low sulfated ash to minimize carbon deposits and port blockage, resulting in reduced maintenance and extended equipment life. Advanced anti-wear and anti-scuff protection helps control valve recession and wear on piston rings, cylinder liners and bearings during continual severe-service operation.
  • AMSOIL Synthetic Stationary Natural Gas Engine Oil is engineered with premium base oils and additives to improve engine lubrication by keeping oil passages clean. Its balanced formula allows for a high total base number (TBN) to protect against corrosion while meeting low ash requirements.
  • Nitration is a common concern in natural gas engines and can cause oil to thicken, reducing efficiency. AMSOIL Synthetic Stationary Natural Gas Engine Oil is naturally resistant to nitration, delivering maximum engine protection.
  • AMSOIL Synthetic Stationary Natural Gas Engine Oil is formulated with low zinc and phosphorus levels to prolong the life of emission catalyst systems without sacrificing wear protection.
  • Extensive monitoring by oil analysis has proven that drain intervals can be safely extended with AMSOIL Stationary Natural Gas Engine Oil. When extending oil drain intervals, change the oil filter at the equipment manufacturer's recommended interval.
