What are these GM-LL-A-025 and GM-LL-B-025 motor oil requirements? Do they apply only to cars in Europe like the Opel and Saab? It is my understanding that the EcoTec engine was developed in Europe. If so, and if these engines need oils that meet these requirments, then somebody better tell GM dealerships and Saturn dealerships. Either that, or we better go to the nearest Saab dealership and stock up on oil.
