Has anyone used amsoil 75w90 gear oil in the 5-speed tranny? What is
different or special about Honda manual transmission oil? I understand the amsoil gear oil increases fuel mileage.
I recently changed my MTF at 30K miles with new Honda manual transmission fluid (which btw is cheaper then 0W-20 oil). I know this was half the recommended interval, but even after 30K new fluid made a noticable difference.
