Ti doesn't make a bit of difference, at teh same time it seems the reformulation did not reduce quality of the oil either. Great report, thank you.

You’re to kind. I finally changed the oil after all these years. I have preferred to imitate the NSA in the past. Just snooping around in the background. I could say, “I was at work, or was I out fishing.” BTW: The wife tells me, “I say too much.” Just a heads up, I even plan to post again later this year. Oh, now I’ve gone and said to much.

OP, Thanks for the UOA, it's good to see a Euro A3/B4 oil tested, and good to see the difference between the Castrol Edge both with and without Titanium.

Both performed very well, nice low iron numbers.
