CASTROL AGT-STD
Turbine and Gas Engine Lubricants
Neopentyl polyol ester based high-performance aeroderivative turbine oil for ground gas turbines.
Its base oil is fortified with carefully selected anti-oxidant, anti-wear and anti-corrosion additives.
Castrol AGT-STD is a lubricating oil with a viscosity of 5 cSt at 100 °C. It has low coking propensity, high resistance to oxidation and thermal degradation and high flash point.
Performance claims and approvals:
MIL-PRF-23699 G Class STD lubricant
