It seems to be Bob. I sat in on a tech seminar regarding engine oil at the Mopar Nationals in Carlisle. The speaker there recommended Valvoline Blue 15w40, which is a diesel oil and similar to Rotella. Cummins recommends Valvoline Blue. It just goes against everything we have come to understand to pour diesel oil into our muscle car engines.
