Castrol AGT-HTS
Castrol AGT-HTS is a lubricating oil with a viscosity of 5 cSt at 100°C. It is based on neopentyl polyol esters with high thermal stability, fortified with carefully selected anti-oxidant, anti-wear and anti-corrosion additives.
Strong thermal and oxidative stability allows Castrol AGT-HTS to resist breakdown at elevated operating temperatures, helping the product retain its protective properties under demanding duty cycles.
Excellent low-temperature performance supports reliable cold-start flow, ensuring that critical components receive lubrication quickly even in challenging ambient conditions.
Castrol AGT-HTS has been designed for use in aero derivative gas turbine engines in ground gas turbines (aeroderivative) including marine and off-shore installations. It is tailor-made to ensure 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.
Castrol AGT-HTS is manufactured to Castrol’s standard tolerances; users should consult the safety data sheet for handling, storage and disposal guidance.
