Be careful who you listen to on forums. Also know the law. Specifically LAW: 15 U.S.C. §§ 2301-2312, Also known as Magnuson Moss Warranty-Federal Trade Commission Improvements Act:

So in short (Since you probably wont read this in it's entirety
) Oil changes are a recommendation and not a requirement. Any required maintenance would have to be performed by the warrantor at their costs. If for some bizarre reason your oil did go bad...(unlikely) they would have to prove that to deny service. My first oil change on my Cat was done at a year and half. Oil was perfectly fine.
Just protect yourself, always take a sample of your oil and have it analyzed should you have any warranty concerns. A good one is:

The 6 month oil change hype (as well as the ms12633) is nothing more than a strong arm tactic to push uninformed consumers into a bunch of unnecessary maintenance.
Oil life is determined by many factors including time.
Also if you don't take anything else away from this thread, remember it's (NEVER) your responsibility to prove anything to a Dealership. The burden of proof is solely on them. If you find yourself in a situation where a Stealership is asking you for receipts or anything similar, run for the hills because you are dealing with a very crooked entity.
You as a consumer never have to prove anything unless in the extremely rare case this kind of situation goes to court. And a Dealership is going to make damn sure they have a 100% winnable case before that happens, because they are responsible for all legal and court cost should they lose.
Hope this helps and here is a Sample of oil analyses performed by Blackstone on my 4th oil change:
