You certainly wouldn't do one if there was another option...Also as OEI is a flap 15 approach on most older aircraft it's not certified at all for Autoland at this setting.
Later aircraft do have F30 OEI figures. If your company allows it.
Fail Op aircraft have F30 OEI figures. Autoland? I'd rather not...
If you have an engine out you really shouldn't be going somewhere with CAT3 weather...#
