Many popular North American engine oils may actually be harmful to European engines. European automobile manufacturers design vehicles to use specific high quality lubri¬cants with specific properties and additives. Most motor oils offered in America do not meet the demanding specifications, and the European lubricants are not readily available. As a result, problems such as premature wear and engine sludge develop.
"Europeans build their cars and impose higher requirements on the type of oil than we are used to here in North America," remarks an oil industry source. "They have more of a multi-tier system within their specifications, whereas the API uses the lowest common denominator as a guideline.
It is by its own admission, within API 1509, a minimum Spec.
While the American Petroleum Institute (API) sets oil standards in America, the Automotive Manufacturers Association (ACEA) sets them in Europe. "ACEA standards reflect a wider complexity of the offering of engines on the market right now," says Herve Blanquart, VP Automotive of Motul North America. "On top of that, manufactur¬ers have introduced their own standards, most of which start with the ACEA standards, and go further in specific tests to solve specific problems and address specific issues." In the U.S., the API adopts one standard for all engine oils. "For example they are work¬ing on ILSAC GF-4, and the problems they are running into is that this oil will be too thin for a lot of older engines," explains Blanquart. "In Europe, they decided from the beginning that they would not adopt a lin¬ear standard - rather a standard for each type of application - gas, diesel, turbo, etc."
