Castrol Duratec L is a monograde gas engine lubricant that provides excellent thermal and oxidative stability
to reduce combustion chamber deposits and significantly reduce maintenance costs.
Duratec L is formulated primarily for spark ignition natural gas engines where the gas is largely free from
aggressive components such as hydrogen sulphide and chlorine or fluorine compounds. Duratec L has been
specifically developed to reduce deposit formation, and improve oxidation characteristics whilst offering excellent
corrosion control and base oil retention.
Castrol Duratec L is approved by R-R Ulstein, Wartsila, Perkins, Ruston and Mirrlees Blackstone,
and meets the requirements of Caterpillar, Jenbacher, Waukesha, Guascor, Deutz and MAN.
