Does anyone remember ARCO Graphite Oil? (Motor Oil)

This oil was real popular in the 70's, then it seemed to just vanish.
What ever happened to it?

Did you use it? If you did, what was your opinion of it?

Although it cost a little more that plain oil, I bought it, since it was
supposed to be a superior lubricant. I never had any problems with it,
and I was using it on some high milage old cars that lasted almost
forever. So, I was pleased with it.

But all of a sudden it just disappeared from the store shelves and I
have not seen it sold in years.
