Short answer, use the spec oil your engine manufacturer specifics. There is absolutely no reason to make oil choice a science project and potentially destroying your engine.

Is CK spec oil usable in my car? IDK or care. Unless VW approves it for my engine, I will not use it.

There are TWO new oil specifications coming out. CK (has the conventional SAE "donut") is backward compatible, meaning you can use it in engines rated for older specs (such as CG-4). It's fine to use in your ALH.

The other oil has one of the top "quadrants" on the SAE "donut" filled in red. It is NOT backward compatible - don't put it in any TDI.
