I have been running Shell Rotella 5w40 synthetic oil since yesterday and have put on about 300 miles with no sign of oil loss. But in the event that I do starte losing some of it would adding a high-moly oil like Redline 10w30 to it have any benefit over just adding more rotella? The rotella seems to be a very good oil, keeping the engine running smoothly and quietly.
