I'm heading to Walmart. If this stuff has no carbon, there's no way I'll ever have carbon build-up. Other oil companies can either shut down or do something else.
Walmart told Pennzoil Ultra Platinum to get out of Dodge by sundown (Walmart shelves) a few years ago.
Both PUP and Castrol Edge EP can be ordered online and shipped free to your front door.
This makes me want to throw a bunch of my used oil in the trash pit and burn it.
I never separate the plastic or aluminum either.
Just burn it all and then stomp the cans flat. After so long the aluminum cans deteriorate away from multiple trash burns.
But seriously I don’t usually burn oil.
