Arco Tests New Diesel, Seeking Less Pollution

Atlantic Richfield Co. began a fleet demonstration program of its new experimental diesel fuel that the Los Angeles-based oil company hopes will make dramatic reductions in air pollutants from trucks, buses and cars. More than 160 vehicles will participate in the yearlong program to evaluate the new ED diesel fuel and new exhaust treatment devices. Included in the program are Los Angeles city refuse and street maintenance trucks, Santa Monica buses, Ralphs Grocery tractor-trailer trucks, some Hertz pickups, San Diego school district buses and Arco gasoline tanker trucks.
