UOA on my wife's 2012 Mustang with the 3.7L V6. This is High Performance Lubricants HDEO 5W-20, the CI-4 version. The filter was a Fram Ultraguard XG10575 which I will do a C&P on soon. Total miles on the car is 157,065 miles and the oil has 20,467 miles.
Some slight oxidative thickening with the KV100 in 30 grade range which isn't a problem. The silicon increase is likely due to an old air filter (nearly 50k miles) and the fact that it gets driven down dirt roads at least once a week. The TBN still looks good. I changed the oil with High Performance Lubricants PCMO Premium 0W-20 and another XG10575 filter.
