Asmodeus, mon ami,
Je n'ai pas lu ce document particulier mais je pense que je comprends qu'il contient. If an OEM REQUIRES you to use a specific brand or type of oil, filter, etc to keep the warranty in effect, he must provide it to you free of charge (in other words if you are not free to choose from within a "universe" of qualified items); however, an OEM could possibly "nail" you if you had, in this case, a lubrication-related engine failure and he could prove that it was because you used an oil not meeting the specifications he laid out in the owner's manual (e.g. an SJ oil when SL was specified or a 5W30 when a minimum of 15W40 was specified). This is an unlikely happening, but since it is possible, I like to caveat my advice with the warranty aspect so the person understands the possibility, however remote. In this case, if say a 5W30 is recommended for the Saturn, I have NO DOUBT that M1 0W40 will handle the requirement safely. I just wanted to be sure that 94saturn...knew of the warranty consideration.
