From what I can find on the web…I think you’re correct that the Moebius A is 9010.
The S-4 and S-6 appear to be grease, and I can’t find any direct correlation between Seiko’s oils and the Moebius products.
I think that you will have to find the specific properties of the two types, and try to find which ones seem to be the closest.
Perhaps,…you may try to contact Moebius directly ????
