Given Honda now only supply DW1, would it be fair to say all models would be ok on the post 2010 alternative oils (Amsoil ATL & Redline D6)? Clearly post 2010 models shouldn't use the earlier, thinner oils.
The earlier atf were thicker.

The dw1 is the fuel-economy edition atf that's thinner than the z1.

The z1 replacements are cheaper than the dw1 replacements. So if you got the older oil as factory fill I don't see the sense in paying substantially more for the dw1 equivalent.
