Castrol ATF

I’ve gotten chastised a bit for this on other threads - but I don’t trust the multi-spec fluids. They are engineered to meet lots of different specs so they will minimally meet them all - but are all of the specs really optimized? Well, they can’t be optimized for your exact specs since some things are bent to accommodate other things. I’ve always thought of them as probably “good enough” but not “optimum.” The exact spec will generally cost a bit more but to me it is cheap in comparison to messing with the health of the transmission.

You will, of course, get varying opinions.

FYI: with some internet searching you can find the exact Honda specs and then you can find them for any fluid on the market to compare.
