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.

Forget the 75W90 gear oil. As John suggested, it is definately too thick! In cold weather it will feel like you have corn syrup in there!

Again, as John suggested, try 10W40 or stick with MTF.
