The North Carolina Department of Agriculture and Consumer Services last week said it issued a stop-sale order for tractor hydraulic fluid products labeled, claimed or implied as meeting THF 303, a specification discontinued in 1974 and subsequently replaced with the current JDM-J20C or D specifications. The agency said manufacturers and distributors have six months to remove the products from retail locations, and retailers or distributors with the product in stock should return it to their suppliers. Colleen Murphy-Smith was appointed as director, base oils for Motiva Enterprises LLC. She replaces Bryan Schorzman, who was appointed director of refining and strategy analysis. Midland, Michigan-based Savant Group appointed John Bucci vice president of technical development.
