Anyone using 75w/110 or 140?
Thinking of using one of these weight gear oil in my diff, car has 63k and is a manual trans, may do a few track days, little or no winter driving, any disadvantage to going a little thicker? Thanks

I am prejudice, because when I retired I went to work for Red Line Oil, and we are the only PAO Ester product out there, so it handles heat better than anything else available.
Just a footnote, I used it for 15 years before they hired me.

DTE Rebuilt my differential about 8 years back. Got the street version stage 2. They recommended Redline 75-140. I called them and asked to talk with the tech and was told that with their testing and experience it was the preferred oil.
I do not track and the diff is quite.
They changed out the clutch packs to carbon and upgraded the oiling system along with cold treating the ring and pinion and had the ZO6 half shafts installed. Also micro polished all the gears. Went with 4:10 and a great mod for the MN6 giving more control of the engine and enhancing driver experience. Still it should do over 150 mph so it isns't gear bound for the street, as some might think.
Anyway they where acquired by Hoosier Performance a few years back.

BG product Syncro shift II specifically created for tranny's that use ATF, you won't believe how quite the car will get, been using it for about 6 years, NO advantage trying to out think the people who built the car BTW they've been building cars for over 100 years.
