So I got the UOA back from my wifes cousins car I take care of for them. This car sees 95% highway runs as they live in a rural area and put on 1,000-1,200 kms per week. The way I see it, this is the most optimal operation anyone could possibly ask for. Because of the huge mileage, we decided to leg it out for 15,000 kms and see how it went. They are showing more than 5% fuel dilution, but no abnormal wear metals. Also the way I see it the TBN is still strong at 2.37 as is the cSt at 7.4. Aside from the fuel dilution I'd be inclined to say this is a successful run, but I'm not sure how to proceed. Any suggestions?
