Thanks for the distinction. The Manual doesn't specify that it is a 502.00 specifically (they also list 503.00 and 504.00), but I did find the VW approved list for 502.00. I intend to use Mobil 1, but was a little surprised not to see Shell Rotella, 5W40 on the list. I used to use Rotella on my Volvo Turbo Wagon and found it to be a great oit.
I live in NW Wisconsin which, most years, gets temperatures below zero for days on end. Not this year, though.
