i'm sure Arco probably figured it was better to discontinue the product, rather than risk future lawsuits for claims of damaged engines in new cars.
If you had an older, carburetor car, prior to 1975, built for leaded or low-lead gasoline then the graphite oil was okay. However it was the cat converter cars where the issue arose, and unleaded gasoline.

A very good point. I never gave that a thought, I could see it affecting the emission stuff. If you didn't have a CAT on your rig you would be OK. One big plus to fuel injection is it doesn't contaminate the oil like carb engines. I may need to get a tube of graphite and dump it into my oil the next change.
