Pretty sure that T4 is conventional, T5 is a con. syn. blend, and T6 is a full syn.
It was. I looked it up and in 2021 Shell changed the formula and now it's a blend.
F6Dave:
As i mentioned earlier I recently switched from Mobil 1 15W-50 to Rotella T4 15W-40. I had the oil analyzed for both. Wear metals were the same, but they use different anti-wear packages. Mobil 1 has more moly and magnesium while Rotella has more boron and calcium. In my Valk it made no difference.

I hate going here.... but on T6 .... what is the change?
Per survey, it doesnt seem to concern many of us.

Yeah idk, I've been using T6 in my motorcycles for over 20 years now and this is the only site I have seen someone say something about a change to it that effects motorcycles? The bottle has a picture of a motorcycle on it and it still says JASO on the back so unless I see some type of concrete evidence that I shouldn't use it, I'll keep using it. It's in both of my bikes right now.

T6 5w40 does not meet the Ford spec so shouldn't be used.
the T6 15w40 does meet the Ford spec and can be used.
