摘要

Lubricant formulators and their additive suppliers are being challenged to develop new formulations for passenger car engines and heavy-duty diesel engines, in response to U.S. Environmental Protection Agency directives requiring reduced vehicle emissions and customer demands for better fuel economy. Starting this summer, the new ILSAC GF-4 passenger car engine oil category will be expected to maintain catalytic converter efficiency for 120,000 miles. At the same time, these oils must reduce by 20 percent the current level of phosphorus they contain. Phosphorus is a proven component in antiwear protection but known to slowly poison the catalytic converter in the exhaust system.
