If you look at the image on the nulon oil from super cheap, its compatible with Honda Z1 and DW1 so it should be alright. The nulon oil has been used frequently amongst accord users. I think Fredoops is currently using Nulon and he has a lot of experience with ATF. I personally use Redline D4 for my accord, its good but expensive (double).
oh thanks for explaining things.

Yes I am following the service book thing. it says to change ATF @ 120,000km . so does it mean i only need to drain and fill it once on the civic ? i was reading another thread it said some people drain and fill 3x ( on the accord)

Also, is there a transmission filter on the civic that needs to be changed ?
