ATIEL, the European lubricants industrys technical association, announced it has developed new guidance for engine lubricant marketers on making valid performance claims against more than one category within the ACEA (European Automobile Manufacturers Association) 2012 European Oil Sequences. In a news release, the association said the guidance is in response to findings of an ATIEL quality survey that revealed a number of products on the market bearing incompatible or incomplete claims.
