a giant leap from the currently accepted norm, where OEM specs are typically established only for specific vehicles that truly require the additional protection guaranteed by adherence to a more robust OEM specification
So much for the "big oil" theory......
"(ACEA), was founded in 1991 to represent the interests of the 15 European automotive manufacturers."
"The vast majority of motor oils in North America meet or exceed ACEA standards"
"The International Lubricants Standardization and Approval Committee, better known as ILSAC, is a consortium of the automakers - General Motors Corp., Ford Motor Co. and Chrysler LLC - and the Japan Automobile Manufacturers Association"
Ummm, GM is doing this for *all* their engines. Instead of a few. "for all motor oils which are to be used in ANY of their vehicles."
Again, from his own links. And again, so much for "big oil".
