TEXACO <TX> TO CEASE POSTING TEXAS OIL PRICE Texaco Refining and Marketing, an operating subsidiary of Texaco Inc, said it would cease to post crude oil prices for West Texas crudes at the end of this month following a decision to discontinue purchase of crude oil from leases, a Texaco spokesman in Houston said. But it will continue to purchase quantities of U.S. and foreign crude oil for use in its refinery system, he added. The spokesman also said Texaco Trading and Transport Inc would continue to acquire and market Texaco lease production as well as other lease production. The company will continue to post a Louisiana price, it said.
