C'mon, man!I was slumming today BITOG, yes I am ashamed of myself, not posting just reading. But look at the molekule's opinion why you see copper wear with redline... I will post his quote in full, I'm not sure what more you want for tbn, I would say add more mag, but whatever. Seams like ca levels are high to me. His opinion here..
I think the cleanliness AND the soft metals issue are one and the same. The DD levels are low for a synthetic oil and I believe it's because of the high ester content in RL, which make very good scavengers. I do not think the esters are attacking any soft metals, just cleaning the surfaces of bearings, due to their high polar affinity to metals. I do agree that RL's tbn and tbn retention could be better given the price. I think their calcium levels need to be about 1.5 times more than current levels.
You can't be that bored in your beautiful climate. We still got 10 inches snow ice and cold breeze. I worked on Harley engine today, still haven't changed truck trans oil.
