Found this product from Lucas Oil and ordered six 16 oz bottles on Ebay for $84. In the process of trying to locate a DPF delete pipe as I found someone who will reflash the ECU to account for DPF delete. Nobody has made a DPF delete pipe for an X5 yet and if anyone knows where to find one please let me know.
Details from the Lucas Oil Website:
