FYI, I found this document dated Jan 2015. Mexico recognizes the importance of establishing availability of this diesel fuel and exhaust fluid ahead of the proposed January 1, 2018 implementation...
Mexico will dribble by dribble expand it's UBA project due to liberalization of allowing "Extraneous" distributors.
When México gets UBA it will make more noise than Saint Patrick's Day in San Patricio, Jalisco. México Distrito Federal luego México the state. Wait and see who brings diesel UBA to México.
