I've read many, many threads re Z-1vs DW-1 vs DPSH here and elsewhere. However, I have not seen the answer to my question. My MDX has 18 k miles. Would I be better off leaving in the FF Z-1 or should I change to the Acura DPSH all wheel drive fluid?
I question if the DPSH is as good as the Z-1. Seems like Acura had to abandon Z-1 for some manufacturing and/or environmental issues. They tried to make the best of things by inventing DW-1 ATF and claiming superior low temp performance in the tranny. However, DW-1 won't work in the rear diff so they had to invent DPSH. Is the DPSH replacement a hastily cobbled together stop-gap or is it an upgrade over Z-1? I have this bad feeling that Acura is going to tell us in a few years that we should dump DPSH and start using a new fluid which they are working on right now because they know DPSH ain't good enough. Thanks.
