yeah but if an when a warranty claim were to come up and they sent the oil for testing and see its superior in all ways they can't use that against you.. Magnusson-Moss.. What a wonderful thing.. Same thing as with using Amsoil Signature Series they can't say [censored] cause it exceeds any spec they put on they're oil
Actually, what it means is that they can't REQUIRE you to use an OEM branded oil. However, if you use an oil that isn't approved, and they DO prove that it caused the failure, they are not obligated to cover it and can void your warranty.
Magnuson-Moss is not carte-blanche to do whatever you want to your vehicle with no risk of repercussions. It is there to prevent manufacturers from forcing you to use OEM-branded replacement and service parts. Which is why we have oil certifications/approvals (required by many euro marques) that ANY oil company can obtain, giving a guarantee of performance for a particular lubricant and also an endorsement from the OEM that the product meets their performance requirements.
If you use a cheap Chinese ball joint that doesn't meet Ford's performance requirements instead of Moog or Motorcraft and it breaks and you get in an accident, should Ford be on the hook to give you a new car because YOU cheaped out? Of course not. So if you use 0w-20 in a twin-turbo BMW and it doesn't meet LL-01 (which it can't, but anyway) and you lunch every bearing in the motor, BMW isn't going to be giving you a new engine either, regardless of whether you claim the oil is full-on awesomesauce or not.
