uuuhhhhh methinks my Ford F350 and '31A will continue with Motorcraft semi syn or Mobil 1. My guess it that "cow oil" wont meet most auto mfrs warranty requirements.

Let's see out of that 3 barrels of oil, we get amongst many other items:
Gasoline
Motor oil
Diesel fuel
Heating oil
Asphalt
and - drum roll - plastics (remember all that Chinese junk in Wally World and the "dollar" stores, and those grocery store bags we all love)
