One additional comment about oil. After extensive research I'm choosing to use full synthetic Rotella in my 2-stroke Detroit Diesel. As I understand the problem, multi-viscosity oils have suffered from low shear viscosity compared to the approved 2-stroke oils. It seems the the full synthetic Rotella meets the shear viscosity requirements of Detroit Diesel while the dino version multi-viscosity Rotella does not. The synthetic version will never be approved for 2-stroke service since the certifying agency has lost the engine (a 6V92) used in the certification process and a bulletin has been issued declaring the end of certifying oils for this service.
Each of us needs to figure out what oil we are comfortable with and this just happens to be my choice. Hopefully the thinking behind my choice will be helpful.
