CASTROL AGT-HTS
Turbine and Gas Engine Lubricants
Neopentyl polyol ester based high-performance aeroderivative turbine oil for ground gas turbines.
Its high thermal stability base oil is fortified with high-quality anti-wear, anti-corrosion and anti-oxidant additives.
Castrol AGT-HTS has a viscosity of 5 cSt at 100°C. It has low coking propensity, high resistance to oxidation and thermal degradation, high electrical conductivity. Therefore Castrol AGT-HTS is recommended for use in hot running engine designs where evidence of oil coking and/or oil degradation was noted.
