Since quoted, going further on Z1. In my observation this subforum Z1 one of if not the most criticized ATFs I've seen here, so attempting to match it's conventional viscosity means very little 'to me'. Z1 was also known to shear very quickly. With couple hundred+ miles using MLFSMV on multiple Honda including 01 Civic and Honda V6, with good service, no reason for me to change now. It should be noted, for that none of the aftermarket ATF add packages matches Honda, including Valvoline and Castrol Import ATF. Being very familiar with the aftermarket ATFs for Honda including add pack and viscosity attributes, link unnecessary for me. In short, to each their own.My 2001 Accord called for Z-1 ATF and I would recommend Valvoline Import ATF (the blue jug being discussed here*) over Maxlife because it's closer to Z-1 in viscosity and still full synthetic. Castrol IMV (not FS) is another choice close to Z1 viscosity wise although not FS. I agree that Z-1 is nothing special......
