This is my first UOA (not sure how to post the PDF). I am using the relatively short interval due to mostly short trips in stop and go traffic. The fuel I believe could be an issue with a longer interval (I am changing the oil every 6 months regardless of miles).

Blackstone comments:
No problems showed up in this initial sample from your Titan. All wear at or below averages for this type of engine, which is a very good indication of normal wearing
parts. Universal averages show normal wear after 4500 miles on the oil. The low flashpoint shows a minor amount of fuel. This is likely due to the 90% short trips
this engine sees and is not a concern, esp. since the viscosity was OK. Insolubles were
low at 0.2%, showing good filtration. No fuel dilution or coolant was found. At 9,500 total miles, his engine appears to be doing well.
