Mobil 1 ESP X3 0W40

So what's the difference between 511 and 504/507?

The most obvious:

VW 504 00: 0W-30 or 5W-30
VW 511 00: 0W-40 or 5W-40

Porsche's equivalent approvals do express it nicely: Porsche C30 and C40.

Sadly the 2019 edition Afton specification handbook doesn't include VW 511 00. Would be interesting to see a current revision as I'm quite sure there are more differences between VW 504 00 and 511 00. Most probably these differences aren't huge though.


must nominally be a 40 grade. it has a higher HTHS than any 504 oil

From what I know both are same minimum HTHS of 3.5 mPas. Granted, in reality a 5W-40 VW 511 00 will likely come with a higher HTHS (e.g. 3.8 mPas) than the typical/average VW 504 00 (3.5/3.6 mPas, only one single VW 504 00 has 3.7 mPas as far as I know).

I've seen this mentioned a few times. "Gas Particulate filter" is just a catalytic converter, right? I keep thinking it's a separate unit like a DPF.
