1. A method for producing one or more cylinder oils of varying kinematic viscosity for a marine reciprocating internal combustion engine, the method comprising:
providing a first fluid having a first kinematic viscosity and a first BN, wherein the first fluid is a system oil, and the BN is from 5 to 30;
providing a second fluid having a second kinematic viscosity and a second BN, wherein the second fluid is an additive package, fresh cylinder oil, or used cylinder oil, and the second kinematic viscosity is different from the first kinematic viscosity;
providing a third fluid having a third kinematic viscosity and a third BN, the third fluid being a base oil and the third BN being less than 1, and
blending the first fluid, the second fluid, and the third fluid in a first ratio to produce a first cylinder oil having a kinematic viscosity of 8 to 12.5 mm2/s at 100° C.
