does not. By using straight weight engine oils you are using ancient techno=

etc. We use 75w/80 gear oil in all but our racing boxes. These use a 75w s=
ynthetic oil. One of the boxes, a pre-war jag box had over 30,000 miles of =
rallies on it before it broke a gear tooth. There was no evidence of abnorm=
al brass wear on the syncros. I have never had an oil engineer in 25+ years=
of business tell me that hypoid oil attacks brass. The light weight gear o=
ils shift better and protect your gears better than any engine oil.
