Nearly all railroads in North America have been recycling locomotive diesel engine oil during the past three decades. During this time, rerefining has developed from simple filtration to acid/clay treatment and, more recently, to vacuum distillation. Volumes of additives and contaminants contained in the engine drain oil have increased significantly during the past ten years. These changes have occurred with the increase in specific power output by engine builders and the increase in engine oil drain intervals by the railroads. Rerefiners have made large capital investments in plant equipment to accommodate both new additive technology and antipollution constraints. The production of rerefined base stocks which meet the performance requirements of the engine users will continue to grow as a result of mounting concern for environmental protection and resource conservation.
