Castrol Duratec M is a mineral based SAE 40 medium ash gas engine lubricant. Duratec M is for use in both spark ignition and dual-fuel gas engines. It is formulated for applications where the OEM requires a medium ash product. The detergent/dispersant additive system has been specifically designed to control deposit formation. Duratec M also has improved resistance to oxidation and nitration which ensures a longer oil service life. It also offers excellent corrosion control and TBN retention.
Advantages:
High resistance to combustion chamber deposit formation means cleaner running engines.
High resistance to oxidation and nitration leads to longer oil life and extends drain intervals. This reduces maintenance costs and down time.
Excellent antiwear characteristics provides outstanding protection against piston, cylinder wear and scuffing.
