I am planning on doing a fluid change on my Acura TL with 6 speed auto. It calls for Honda/Acura DW-1 fluid. I was looking on various websites (Redline for one). They list Redline D4 as Z-1 compatible. No mention of DW-1. I emailed their tech support and was assured that it is also DW-1 compatible which kind of makes sense.
However, I went to the Royal Purple website and when looking at their ATF, it specifically states it is Z-1 compatible, but NOT recommended for replacement of DW-1. I know Honda Z-1 and DW-1 are compatible. I wonder why Royal Purple would be incompatible?
I hope this posts makes a bit of sense. Lead me to believe that Z-1 and DW-1 may not be as compatible
as I thought.
