Is NOT the oil to use in the 2.5L engine. Been through this a lot. M1 ESP while great oil, does not have sufficient TBN retention to support the OCIs that are designed in by the manufacturer on NA high sulfur gasoline.
If the OP runs M1 ESP 5w-30, the OCI should not be more than 5k miles.
M1 0w-40 is the better choice for ga$$ers.

From another thread. The US is NOT plagued with high sulfer content and 504 is a good spec of any VW gasoline engine. 502 is not the end all be all for VW motors.

Apparently, I'm the guy with the "shop floor knowledge" who "rudely dismissed" the assertion that 504.00 oils would "not perform well when dealing with 300+ PPM sulfur fuels". This was after questioning the validity of the very claim seen here, that we are provided with fuels containing sulfur limits of 300-1000 PPM.
All I can say is that I pointed out that the figures you were citing were referencing sulfur content by percentage of weight. You suggested that I should "do the math" to get the PPM figures. The only problem with your theory is that simply calculating out hundredths of a percent, by weight, does not give you PPM, by volume.
As to your continuing assertion of high gasoline sulfur levels, and that I haven't a clue what I'm speaking of, I'd suggest you get your facts straight before "trying to explain" them to anyone. Spreading falsehoods does nothing to contribute to the knowledge available on this site.
Here is the current Code of Federal Regulations requirements for gasoline sulfur levels...
http://ecfr.gpoaccess.gov/cgi/t/text/tex....8.48.3&idno=40 as provided by the Government Printing Office. I don't know how you can get a more authoritative source than this, when it comes to what the requirements are. If you've got one, I'm sure we'd all be happy to see it.
You'll notice that the "Refinery or Importer Average" limit is 30 PPM, precisely as I have asserted. The "Per-Gallon Cap" is 80 PPM, as stated by bruno, which allows for potential fuel contamination during transport. These limits have been in effect for more than three years.
So, how does this affect your ongoing statements that 504.00 oils can't deal with the US market's "300+ PPM sulfur fuels"?
