Mexican Diesel Fuel - Sulfur Levels Update

Thank you Ed. I also called a Amado Transport that imports from Mexico into the US. They were very helpful and put me in touch with their offices in Hermosillo. They did state that they use ULSD when transporting goods into the US. For those of you that are not aware Hermosillo is a city of over 1M people. They gave me the locations of two Pemex stations that carry UBA (low sulfur) diesel. Amado purchases their fuel from a distributor that does not sell to the general public. I also contacted a Mexican businessman that I know who just so happens to own one of the two Pemex stations in Kino Bay, I have yet to hear back from him. I am familiar with Benjamin Hill and do know there is a large Pemex station there. I will check it out.
I am not new to Mexico but am to diesel. I have had a home in Kino for 45 years! Thank you all for your assistance.
