So here's the first UOA I've ever done. The make-up oil is from a defective drain bolt crush washer, not from oil burning. I know this because I discovered the leak one day in the driveway after the car sat for about a week, and it amounted to about this much. The iron levels might be related to me driving hard sometimes and also doing some towing twice during this OCI, but I really don't know for sure, maybe someone else does? Also this is with a K&N air filter (with good silicon levels!) and a WIX oil filter. Any thoughts on this analysis would be much appreciated.
