It's not a question of what it'll do. It's a question of principle and how this information can be used to give you grief over a potential warranty claim.

Better tell all the other oil makers the same thing...
The other oil makers that say "meets" instead of "recommended for" know what the HT/HS viscosity should be.

And BTW, ACD is a A3/B3 oil, no B4.
It doesn't change the fact that HT/HS viscosity needs to be at least 3.5 cP.

EDIT: Also, "recommended for" is a legal term, if your engine blows up, and it can be proven that the oil was responsible, Amsoil is on the hook BECAUSE they used that term.
We are going in circles here. Yes, Amsoil is on the hook, but as was pointed out earlier, every corporation has a legal team that gets paid to get them off that hook. While in the end the customer will likely be taken care of, it just adds unnecessary aggravation to the whole process.
BTW, zuluplus30's question about SSO and XL exceeding dexos1 specified SAPS limit has also gone unanswered.
According to Amsoil Technical Support.
(This is not an exact Quote)
The SS line has a SA% of 1.5%. When asked why the label implied DEXOS1 compliance, the question went to a second level and I was called back. The answer was: Due to the extended drain capablity and low volatity of the oil, the performance of the oil or potential poisoning of emissions systems was not an issue.
As to the XL and OE, both are
Seems this was the case Amsoil made for Phosphorus being over 1000ppm in the API SL standard days.
I also sent an Email regarding the ACD being recommended for ACEA A3 while showing a HTHS of 3.4 on the Data Sheet. Awaitng a response.
I expressed my frustration with labeling verbage and warranty in that Email as well.
There is no doubt Amsoil products perform, and no ones engine is likely to fail, BUT I agree their labeling has lot to be desired and creates more questions than it answers. The label needs to state claims. If they don't want to be compliant with DEXOS1 SA levels, or any other spec, leave it off the label. People just don't want the hassle in case of a warranty claim. Even if Amsoil and the MOSS act wins out and the OEM fixes it, how long is the customers car out of service unless he fronts the money to fix it.
