Anyone here happen to use Idemitsu H Plus on their Honda automatic? Any noticeable change in performance? It gets somewhat mixed reviews online. But as far as I can tell; Idemitsu makes Honda DW1. Whether or not H Plus is the same exact stuff or not I do not know. I need to do a couple flushes but wanted to see if I could get some real feedback before I order it. It will save me $68 if I can use the Idemitsu. Thanks for any input.
