I just purchased a 20L bucket of the Subaru Extra-S 75w90 gear oil. I will not be able to use all of it. I paid about $150 including shipping. That amounts to $7.50 per quart. I am willing to part some out for what I paid. Not interesting in shipping at all. I am located in the San Francisco Bay Area if anyone wants to get some for the tranny.
PM me if interested.
