My Walmart nicotine patches are helping me quit smoking right now (so far so good
), and I am 99% sure they don't make them. They are like 40% cheaper than the Nicotrol ones though for the SAME THING. If memory serves, Consumer Reports did a small expose on battery manufacturers once. They stated that there were only like 3 companies in the world that made small consumer batteries (C, AA, etc.) and they managed to track down who made Walgreens Drug Store and a few other rebranded batteries. Very interesting. Though not entirely applicable to this thread, rebranding DOES occur. Sadly, we don't know who makes what in the motor oil world.
Unless we have any oil industry types lurking here willing to spill the beans!
