As of October 1st 2006 the US. federal Government mandated maximum sulfur content for all oil based diesel Fuel additives available and used in the 50 States and its territories. In light of this Federal mandate, questions have arisen from many of our distributors related to whether the addition of Sea Foam® to these new ultra low sulphur Diesel fuels affects sulfur content. All Sea Foam® products meet Federal ultra low sulfur diesel fuel maximum sulfur content regulations.
