And RFG limits aromatics content..
And RFG is only mandated in 9 major cites-Baltimore, Chicago, Hartford, Houston, Los Angeles, Milwaukee, New York City, Philadelphia, and San Diego.
If you live outside these areas your not seeing RFG fuel in all likelihood.
The overall level of ignorance in fuels in this country is ridiculous and some posters on this thread are a great example.
I'm actually making gasoline for fun and profit as I type this. Latest lab results show nearly zero benzene and xylene and single digit toluene levels. Benzene, Toluene and Xylene are the aromatics that can be found in gasoline BTW.
