When I was in high school, I worked at a service station (not gas station) that used to do "engine flushes." That was idling and engine with 50% kerosine and 50% cheap bulk oil for a bit. Of course, it drained out black but I always had my doubts on what it did to an engine. Is that the kind of flush you're meaning?
