I just bought some amsoil series 2000 75w-90 gear lube yesterday from honda dealer. Is this the right oil for a 1300 final drive. Amsoil doesn't have it listed on their website. It's a green color and I bought it because final drive keeps leaking where drive shaft mates with final drive and I thought I would change to this lube to determine if it was just residual oil leaking from over fill from dealer putting way too much lube or the seal is shot. I figured if it starts leaking green after changing it one of the oil seals is is shot. Does this make sense.
