My old SRC3 and my Sachs Duomatic need three types of lubricant: lithium grease for the ball races, Sturmey brown gunge or oil for the epicyclic gears and something very heat-resistant for the coaster brake ring. I've found Cera-Tec brake grease to be good. Of course, it all ends up mixing to some extent.
