got plugs loose with b-bar. and threads spun off great on fill plug. very little fluid in case - little on the plug smelled pungent like rotten eggs or certain firecrackers (d3 atf smells a bit sweet to my nose).
exact number on GREEN LABLE - SPECIAL OIL is
HWB - Best. - Nr. 81 22 9 407 305. (what does this refer to???) - also below this number is an icon of oil can with x'd out 2000km
I bent a plastic straw and tried to angle and dip it to the bottom of casing by drain plug but got nothing. since I think there is next to no fluid in there I was wary of loosening drain plug far enough as to let a little drip cuz I didn’t want plug to come out and what little to all spill out.
almost certain this is the stuff to use Royal Purple Gear Oil
