Looking the “best” 0w30 504/507 . It’s for a very high performance car in which that grade & spec is recommended from manufacturer. Few have said Mobil esp 0w30 is just about the best you can buy & few recommended shell equivalent . Does some brands of oils have higher oil consumption than others too ? What’s you all recommend . 0w30 grade is recommended & used from manufacturer btw so am sticking to there advise & recommendation . 
Which car, which country?
I've never seen any VW group recommendation for a 0W-30 since 2004 or so.
Before that VW had VW 506 01 (so-called 'Longlife II') which was a low HTHS
0W-30. However VW 504 00/507 00 is either 0W-30 or 5W-30, meaning you
can use 5W-30 alternatively.
That said, while I personally won't use 0W-30 I would go for these
if I
had to:
- Mobil1 ESP 0W-30
- Ravenol VSW 0W-30
- Shell Helix Ultra Professional AV-L 0W-30 (probably same as ECT C2/C3 0W-30)
Generally the 5W-30 sisters M1 ESP 5W-30 and Ravenol VMP 5W-30 are more
stout and have lower Noack evaporation losses. VMP also has a higher HTHS of
3.7 mPas, which is higher than any VW 504 00 0W-30 I've seen so far.
At least in Europe there's a tremendously huge choice of VW 504 00/507 00 oils:
Since I've noticed some members have repeatedly been searching for a dedicated list of Volkswagen approved engine oils and some tried to help by uploading PDF sheets, which inevitably suffer from getting outdated quite soon, I will post these links offcially provided by Volkswagen's "erWin"...
