Interesting. I thought it used to be more of a 30w some years back... and not just because 5w-30 motor oil was an approved substitute.Honda MTF is low 20 weight with cSt of 6.3 or something close to that. Amsoil MTF on the other hand is around 9.6cSt and is a 30 weight. So, there's quite a bit of the viscosity difference between the two.
I wonder if they changed the formulation in the last decade or so to make it lighter still?
