It is a really hard to reply question.
Kluber is a highly specialized lubricant maker, and his quality is superb.
I think that none of the lubricant makers not even the biggest ones, has a catalogue matched to Kluber... there are some cross reference tables across the internet, but i think that you will have to compare many brands to find the one that matches kluber tightly. In my opinion In my opinion the ones with the biggest catalogues are Mobil, Fuchs and Shell. I hope that somebody else reads your message and gives you clearer information than mine.
