Some of the CARQUEST motor oils are now produced by one of the two Warren named oil companies, not sure which one. The Amalie made products come in a white cardboard box, and the Warren products come in a brown cardboard box as of late. The bottles have a different shape ( both the quart and 5 quart). I'm not sure about other lubricant products ( gear lube and greases e.g.) .
Yeah, the guy I talked to could only vouch for the synthetic gear oil coming from Amalie. He wasn't sure where the motor oil came from, but he said somewhere in NC.
