UPDATE.
Well it's been 3(?) weeks now? I found out today, Isuzu is covering it! Thank God!
I have to go pick it up still, but they covered the whole deal. After I sent all my service records in, they were super accomidating.
So, Lesson Learned, KEEP YOUR SERVICE RECORDS! or you can usually get them online from whatever company does your oil.

I'm kind of excited now, because it'll be the new updated 3.5 (Axiom) engine. Should be fun to feel a little more umph under the hood.
