According to this article from Lube Report, it seems that the folks at General Motors are predicting the demise of the ILSAC motor oil certification system. That would mean no follow-on to GF-5, and probably mean that each automaker would be responsible for developing and licensing its own specification of motor oil (a’la dexos). That would not be a positive development for the industry, as inventory requirements for stocking motor oil would be as bad or worse than ATF. Let’s hope everyone involved can take a deep breath and work things out, though from the sound of it GM has no intentions of playing nice. They’ve taken their ball and gone home!
