It’s also because the approval isn’t about the grade it’s about the minimum HT/HS. Grade is irrelevant in this instance. Go with the approval and forget about the grade.Thanks for the reply. My current fill is PP LX 0w30 and it's closing in on 5,000 miles. I'm going to drain it and send it in and fill it with either
Mobil 1 ESP 0W-40 or something similar. I can't seem to find any 40W oils that are VW 504 approved, any idea why that is?
