I don't think it's an ethanol issue. IIRC, it's an issue with US gasoline having too much sulfur.
The sulfur issue is one which hasn't existed for some time, despite the fact that others have continued to impress it upon others. Here is an example (with the name redacted since I won't use it to cast aspersions on another member) of what I mean, with my references showing that the sulfur levels are not what they are often posited as being...

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"?
