Not true, calcium is dominant over magnesium. See the used oil analysis for my BMW.

I phrased it poorly, I meant GC uses higher levels of magnesium than most oils and less calcium than most oils. Like Mobi1 1 (except for Mobil 1 0W-40 IIRC), GC still has more calcium than magnesium. I believe magnesium is more potent than the equivalent of calcium judging by the additive packs of some HDEO oils...

I believe so, but I didn't check all the spec's that closely...
