Pete,
There is a site on the web with an article entitled "More than you ever
wanted to know about motor oils". It is tittled correctly. The first
page shows a chart which shows 80-90 gear oil comparable to 20-50 grade
motor oil.
The address is HTTP://www.vtr.org/maintain/oil-overview.html
The article discussed zinc and other high pressure lube additives with
respect to motorcycles many of which use a common oil/gearbox sump.
Check it out. It is a great article.
