VOA of Mobil 1 Delvac 50 transmission fluid.

To be used in a GL-4 75W-90 gear oil application (Smart ForTwo in my signature)

Interesting. Castrol Syntrans multivehicle 75W90 was generally my pick for this Motsu/Getrag (?) transaxles. But I don't know if you have this in the US...doesn't matter, they cheapened out the formula recently, and I'll have to find something else !
 
So this is interesting.

Someone posted your VOA in my thread about the Mobil Delvac synthetic transmission fluid 50

BUT after looking at it in comparison to the Blackstone VOA done on the 5 fluid comparison

Seems the VOA you posted is much different from the one posted by Carbonite Cummins

Are you sure your sample was mobil Delvac synthetic trans fluid 50?
 
Carbonite Cummins was from 2012...

I bet they split the formula into Delvac 50, which is GL-4, and Delvac 75W-90, which is GL-5...

Or I could have forgotten to shake the bottle...

Note that there is a third Delvac transmission fluid, Delvac ATF, which is very similar to Dexron III / Dexron VI...
 
Did you use the newer black bottle for your testing?

Hers's the Virgin Blackstone from Carbonite Cummins using the old silver bottle with the blue cap, quite different.
