Recycled Motor Oil

I have seen recycled motor oil for sale in quart containers. Is this as good as new oil? What process do they use to clean it? Also, have any studies been done to see how well the same brand lubricates after recycling?
I would not use recycled motor oil in my car. Even if they clean it up and remove all the metals from it, the lubricating properties have been diminished. It may work in low-duty applications, but as a motor oil, I would not chance it.
I am sure that it is cheaper than regular oil, but by how much? Let's say $0.50 a quart. An average car uses 5 quarts per oil change. That's $2.50 you saved per oil change. You should change your oil at least every 4000 miles, but with recycled oil, I would do it even sooner, such as every 3000 miles. So if you drive 12,000 miles a year, that is 4 oil changes and a savings of $10 a year.
A new engine costs on the order of $1,500. You have to use the recycled stuff many years before you save enough to replace that motor. And I did not take into account the extra oil change that you have to do every year. So, you may not be saving any money at all!
