Castrol Duratec M

Castrol Duratec M is a monograde gas engine lubricant that provides excellent thermal and oxidative stability to
reduce combustion chamber deposits and significantly reduce maintenance costs.

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.
