I recently purchased a 2017 Audi A4 Quattro. The Owner's Manual said I can use any oil that meets the VW 502 00 or VW 504 00 specification. Looking at http://www.oilspecifications.org/oiltool/oiltool.php I saw there were a large number of 30 wt oils that met the spec. However, when looking at their specifications, I noticed they all had TBNs in the 7-8 range. The 40 wt oils OTOH generally had TBNs in the 10-12 range.
My concern is whether an oil with a TBN of 7 -8 can stand up to the 10,000 mile OCI recommended by Audi. That may be fine in Europe where they have low sulfur gasoline, but I have concerns about using them in the US where our gasoline currently can contain up to 300 ppm.
Thoughts?
