Castrol Duratec M is a Gas Engine Lubricant.
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.
• Higher ash content overcomes valve recession problems.
• 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.
