A warranty will most likely never be voided. A warranty claim can be denied. There's a huge difference. As others have said, it must be shown that the mod was responsible for the failure. And unless the manufacturer is willing to provide you with filters and fluids free of charge, the warranty claim cannot be denied based on the use of other fluids that fit factory specs provided that appropriate service intervals are maintaned.
