Yes there is much info on this topic....all over the internet...just search for anything marine diesel related for some of them....Large ships have routinely pumped the engine oil in a certain mix ratio with the normal fuel after filtering when changing oil underway...All kinds of things like that are available when searching...other members here probably have some good sites to go to......
