Honda has replaced the ATF - Z1 with ATF - DW1 permanently.. for all the maintenance freaks like myself go out and get yourself some! I snagged 10 quarts.

 

Yeah, we stock both, once honda runs out of the Z1, DW1 will be the new standard atf...but it will take awhile

 

Maybe sooner than you think.....I stopped by dealer in Houston to get more Z-1 for my 2nd drain/fill, found out about the new fluid at that time, and was lucky enough to get the last 3 quarts of Z-1 they had in stock. With their new DW-1 already out on the shelves, that's it, since they CANNOT BE MIXED, "there can be only one...." (hehe). So you need to do a full flush when switching from Z-1 to DW-1, as dealer stated.

Word is that the reformulated fluid is definitely better than the older one, and even though they say its backwards compatible, we shall see..........
