In addition to a little cleaning by the gas/diesel oil, I suspect that iron is coming from the head work ... camshafts and tappets doin' their little luv dance.

Should be much better next time around if the work was done right.

Look forward to the next result ... from both cars.

Are these numbers accurate! Some drunk must have been running the shift the night they blended this oil. This is frigging awesome! (or is it?)
This oil is looking better and better everyday!

Update.
6,500 mostly city miles (6-months), with oil filter replaced after 3-months.

Head gasket & valve stem seals replaced about 3-years ago.

Looks like ONLY TWO oil-changes per year now!
