STOCKTON, CA - Nine California companies - Toro Petroleum, Coast Oil Company, Van De Pol Enterprises, Allied Washoe, Cross Petroleum, Dewitt Petroleum, Beck Oil, J.B. Dewar, and SoCo Group - are ready to supply every county in the state with Air1, the world's leading diesel exhaust fluid (DEF). The companies are ready to provide the education, equipment programs and DEF supply options, ranging from jugs to bulk, that their customers need to meet the Environmental Protection Agency's standards to reduce air pollution.

"It's easy for DEF suppliers to say they are everywhere, but what we see customers needing more than anything at this point is education. So while we're pleased to partner with these leading California companies to ensure efficient local distribution, we are most excited about their commitment to having so many educated professionals ready to help fleets determine best how to store, handle, dispense and use DEF. This is a brand new product that is mandated and there is nothing worse than having to buy something you don't understand. With the expert support available from these companies across the state customers now have a local resource to help them get comfortable with the adoption of DEF," stated Douglas S. Haugh, Executive Vice President at Mansfield.

Yara is a pioneer in the diesel exhaust fluid (DEF) industry and began providing Air1 DEF in Europe, Asia and Australia nearly five years ago. Air1 is now the largest single global market leader in DEF sales. Yara provides the North American transportation industry with an efficient, reliable supply of Air1 to help meet 2010 Clean Air Act environmental requirements.

Mansfield and Yara conducted training sessions at Yara's new $21 million terminal facility in Stockton and in Ontario, California, for 34 sales representatives now certified as Air1 specialists under the DeliveryOne program. Mansfield's DeliveryOne network is the distribution system for Yara's Air1 in the U.S.

"These nine distributors are the perfect partners to bring diesel exhaust fluid to California," added Chad Dombroski, Air1 Director of North American Operations, Yara. "Their understanding of DEF, a history of outstanding client service, the strength of their teams and the depth of their commitment to educating customers about this year's Clean Air Act requirements make them the go-to distributors for DEF in California."
