only genuine honda fluid??

Each to their own. Honda fluids and aftermarket fluids both have pros and cons. Can I ask why you'd never use honda 10/30 all model oil or ATF-z1 ?

I use full-syn 5w30 (used M1EP, M1, and now Redline)instead of FEO after reading a lot of BITOG. Full-syn allows longer drains and protection, my car don't stack all that much miles so oxidation over time (6mth plus) becomes an issue for dino/semi syn oils since the car could sit in garage And not move for week at a time. So for not much more than the cost of the Dino FEO (I buy my synthetic oil direct from USA these days) I could get higher end synthetic oil, and a horsepower or 2 extra to boot. Honda FEO can claim to be fuel efficient with its friction modifers but the full synthetic I used still beats it economy wise. So Win win for me.

Also, dino FEO is bloody expansive for what it is.

ATF-Z1, well known on BITOG, it does not last the factory rec drain intervals, known to be a source of issues for Honda automatic transmissions. lots of USA-bound honda/acura owners use synthetic atf alternatives as a result.
- even Honda realised that themselves by changing to a synthetic based ATF-dw1
