Has anyone used amsoil 75w90 gear oil in the 5-speed tranny? What is
different or special about Honda manual transmission oil? :D I understand the amsoil gear oil increases fuel mileage.

i know this is an old thread..... but..........

i'm going to try an put in some Redline 75w80 "MTL" in my 2006 Insight, as opposed to the stock OEM Honda tranny fluid

car had nice fresh oil in it upon changing it over, so the comparison should be pretty easy to make. i'll check back in within a month or so and let you all know if it shifts/feels any different w/ the Redline instead of the Honda fluid
