Any time anyone tells you that doing something will "void" your warranty give em the bird. The magnuson moss act of 1975 dictates that no manufacturer can void a warranty for altering a car, and only if there is undeniable proof that a modification caused a malfunction can it be denied as a warranty claim. If your window switch goes out and is covered under warranty and they tell you they wont fix it because you use the wrong oil, get a lawyer you have free money waiting for you in the form of a lawsuit.

AGREED! They would have to prove that the oil caused any failure (which it won't) to deny a warranty claim.
