Automakers Face Engine Failure Costs Linked to Thinner Motor Oils
Five major automakers are confronting financial liabilities linked to engine failures primarily caused by motor oils with reduced thickness. Industry experts suggest that thinner oils, designed for efficiency, are less forgiving of manufacturing flaws in engines, leading to increased instances of engine seizure. The trend towards thinner lubricants, meant to improve fuel economy and meet regulatory standards, has inadvertently heightened sensitivity to imperfections during engine assembly.
