Previous UOA:
This is a sample pulled from my Durango 3.6L with 132,679 miles total and 21,079 miles on the oil. The oil is HP 5w-20 by High Performance Lubricants in Manteno, IL. This oil is intended for extended drain intervals. I will sample again at 25,000 miles. Filter is a Fram Ultra, which was changed at this sample. Consumption was zero. Lab is WearCheck. The oil has been in service since 12/26/2019
The viscosity has increased slightly but the TBN is still 3.985, so we are going to run it to 25,000 miles and resample.
Iron almost doubled in the latest sample. I decided to change the Fram Ultra filter since it had 21,000 miles. This oil has an ester as one of the base oils and from the pictures of the filter, loosened a lot of carbon. The carbon I removed from the filter with my finger was hard and gritty. In the last 5,000 miles there was a considerable amount of high RPM mountain driving. The 3.6L boosts oil pressure and flow at high RPMs, I'm afraid the oil filter was bypassing at the high flow rates and circulated some of the hard carbon through the engine causing the elevated iron. Lesson learned, when you switch to a high ester oil, change the filter every 5,000 miles.
The Fram Ultra was in excellent shape.
