Went to Walmart for an oil change and the guy tells me Supertech is recycled oil made by Pennzoil. He said the oil that's drained out of cars at oil change places is what is used to make Supertech. I asked him where he got this information and he couldn't give me a source. I asked him if the oil in the Supertech bottle was recycled wouldn't they have to say it right on the bottle? He didn't know. Sooooo, BITOG oil pundits, what's the straight skinny?
