While searching the web for info about Rotella T Synthetic, I stumbled onto a Shell web page that said: "Ask the Shell guy a question" or something like that. So I asked him about whether Rotella T Synthetic was compatible with the VW 502.00 spec. Here's what he replied:
===========================================================
Thanks for the opportunity to respond to your inquiry, and thanks for using Shell products.
ROTELLA T Synthetic SAE 5W-40 has not been tested to VW 502.00 oil specification.
Some products that meet the VW 502.00 oil specification requirement include Pennzoil Synthetic European Formula 5W-40 and Quaker State Full Synthetic European Formula 5W-40.
Best Regards,

So it sounds like they just haven't bothered to test it.
