Correct, I believe the relatively high level of titanium in my sample is due to the engine oil I'm using, Castrol Edge 0w40 - they claim to use some patented "Fluid Titanium Technology".

Could simply be verbiage, but it looks like khj24 saw something similar after switching to this specific engine oil. Of course, this is still a very small sample size, so would love to hear from others as well, especially from those using similar engine oils.
