Min T (as described on Lubrizol) is Minimum Base Number.
I would assume this would mean pH value.
The oils ability to neutralize acid formation during the combustion process.

Yes, the normal abbreviation is TBN, total base number. So Ford followed the ACEA specs until 913-D, then required 10 instead of 8. C1-5 are a minimum of 6.
I'm not sure exactly what TBN means - might have a look.
