Finning is what we have locally for analysis, so hopefully this can be used comparatively to Blackstone.
First oil analysis at 319000 km.
I've been changing oil for the last 3 years at average of 7400 km (4500 miles) with Costco/Kirkland 5w30 and Toyota filter.

Can't wait to see my results...

I got busy and went longer than I planned to for this change (9730 km / 6045 miles). Iron and Aluminum up a bit (from the longer interval?) .
With two good results in a row, I will probably only sample once a year going forward.
