What do you mean by min. T?

The SUV is a C3 oil. I think they're just marketing it towards SUV as it only comes in 7L container. I think, the Ranger eg, has a larger capacity sump. Maybe 7L?

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.

I was put off by Castrol's 'intelligent molecules' marketing.
The oil's probably fine but I couldn't bear thinking
about the intelligence of the molecules.

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.
