Really? If it was so bad, how did I get by with using several cases of the stuff in one engine with zero problems? Admittedly, the engine only lasted another 500K or so miles afterward before succumbing to issues unrelated to lubrication.
What I 'recall' being the issues with Arco Graphite Oil is; if the vehicle sat for extended periods of time (don't remember if it was weeks or months) the Graphite would drop out of the Oil and be in the bottom of the Oil Pan or other locations that Oil would normally 'pool'...like areas in the cylinder heads. It did get a bad reputation. Maybe even clogging Oil Filters.
