Was Schaeffer's one of the first companies to use Moly? If so, they must have been ahead of their time. It's not something required, but it is very good. Almost all oils are using Moly now.
I remember "ARCO Graphite". Totally black right out of the can.
The local ARCO was a racer and tried to use it in his track cars.
He said the stuff leaked out like seive.
