Was watching recording of Horsepower TV where they were building a big engine (I think it was a 460 Ford). When it came time to put oil in it, the plastic bottle that was barely visible was silver with a black label on the back. Normally on that show they say what oil brand they are using. I think it was either a Mobil 1 or Valvoline bottle this time around. Did their Royal Purple sponsorship go away?
