Abstract
Disclosed is a method for producing one or more cylinder oils of varying kinematic viscosity for a marine reciprocating internal combustion engine. The method comprises providing a first fluid having a first kinematic viscosity and a first BN, providing a second fluid having a second kinematic viscosity and a second BN, the second kinematic viscosity different from the first kinematic viscosity, and blending the first fluid and the second fluid in a first ratio to produce a first cylinder oil having a kinematic viscosity equal to or less than 14 mm2/s at 100° C.
