Here, I drew the oil tanks (gasometers), marked them as man_made=gasometer, as it’s written in Wiki, but they’re not rendered in mapnik.
Should I add more tags, or it’s a mapnik issue, and I better open a ticket?
Beside the fact a gasometer is for gas and is not an oiltank (http://en.wikipedia.org/wiki/Gasometer) I’m not sure mapnik renders this feature at all.

Oh, now I see, thanks. How can I tag it right now?
If you tag it as building=yes then it will be rendered in Mapnik
A gasometer is probably a sort of building.
