IIRC I bought this bottle at RT-Mart. Supermarkets don’t sell brake fluid any more AFAIK, and its a bit surprising they ever did, since it suggests the Kak-handed Kulture thing is a recent development here, which seems very unlikely.
Anyway, since I never learn, I was confident of getting it at a CPC filling station.
5 big helpings of the M-word from 5 different filling stations later, I’m thinking they’'ve maybe stopped making it.
Since its better than DOT-4 (less hygroscopic so longer service and storage life) and quite a lot cheaper, I suppose its demise was predictable.
Taiwanese seem to use ground coffee anyway.
