So: use ATF but no regular petroleum based oils.

we don't use "oil" as the old SU carbs with their massive aluminum piston did. The Strombergs have the rubber diaphragm which lightens the "massive" weight of the original SU piston but which will get "eaten" up by regular oil. Instead, we use ATF which will not harm the "rubber"(in fact will slightly expand the diaphragm if it get on it) and just fill to the top: any overflow will clean up some carbon build up(has been used extensively for ages just for this). So: use ATF but no regular petroleum based oils.
