Description
Castrol Duratec M is a mineral based SAE 40 monograde medium ash gas engine lubricant that provides excellent
thermal and oxidative stability to reduce combustion chamber deposits and signficantly reduce maintenance costs.
Application
Duratec M is suitable 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 base number retention.

Advantages
• Higher ash content to overcome valve recession problems.
• High resistance to combustion chamber deposit formation which 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 a high level of protection against piston, cylinder wear and scuffing.
