New to the forum.
I have read some comments on some of Blackstones reports and I have a question.
In some reports they state that iron tends to increase with mileage on the oil but other wear metals should follow universal averages even with extended intervals (apparently regardless of mileage).
This doesn't seem to make sense to me. IE if you had 5ppm of AL in a 5k interval, wouldn't it be reasonable to expect 10 ppm (or close) in another 5k on the same batch?
I know UOA is about spotting changes in trends and there are few absolutes but what is it about Iron vs the other metals that is different in a UOA?
Thanks,
Andy
