Also, don't let him use the Mobil 1 5w30 no matter which one it is; it doesn't meet VW502 spec.
Depending on quality of gas, VW 504.00/507.00 is better suitable for DI engines and 5K OCI.
Though, I would say that I would feel confident using that spec for 5k only in California.
I don't disagree with this. That's why I'm currently running Motul 8100 x-clean 5w40, which meets MB229.51 and VW502 (which my car requires). I'm hoping with it being lower SAPS (MB229.51 spec) it'll help slow down intake valve buildup.
VW 505.01 has a lower SAPS content than oils that just meet VW 505. I would consider an oil that meets 502, 505, and 505.01. The current Valvoline 5w40 meets those specs, and NAPA has it.
