Duratec LD is a low ash gas engine oil designed with the total base number required to maintain engine cleanliness, provide resistance to acid corrosion, and protect the engine from wear throughout the lifetime of the oil.
Stationary gas engines are running at higher pressures to deliver greater efficiency and to reduce emissions. This higher Brake Mean Effective Pressure (BMEP) means higher engine temperatures causing faster oil degradation. Shortened oil drain intervals can lead to an increased risk in engine component failure. Castrol Duratec LD is formulated with modern gas engine additives and high quality base oils to delay oil degradation and to extend oil drain intervals.
