This sample was pulled from my 2014 Dodge Durango with a total of 168,000 miles and 28,000 miles on the oil. The oil is HPL's 5w-20 CK-4 based formula and has been run since Feb 9, 2022, about 21 months. The lab is Wearcheck. The usage on this 9,300 mile run was >75% high speed driving down the interstate. There was 2/3 quart of makeup oil. The PCV valve was changed and oil consumption returned to zero until the oil filter/cooler started to leak again (this is not my happy face). All of the fuel used for this 9,300 mile run between samples was E-85. The oil filter had been in use for 4,500 miles and it won't be changed until the oil gets changed. Fe wear rate for this 9,300 miles was 0.65ppm/1k miles. The TBN is still at 6 so plenty of alkalinity left. Viscosity has increased to 12.6, which is barely into the SAE 40 range (12.5-16.29). Corrected Si is only about 8ppm, because there is some Si in this virgin oil. I see no need to change the oil now, so I'll probably run it a few thousand more miles. The oxidation number is way off, so Wearcheck is going to run the sample again, I will update the table when I get new data.
[edit-Nov 7, 2023] Wearcheck ran the oxidation again and found a value of 64.1 (was 17.9), which makes much more sense. The table below has been updated.
We saw the cleaning power of this oil in this bore scope thread.

New PCV valve in the Durango 3.6L
Today I put a new PCV valve (part number 68083202AC) in my 2014 Durango with a 3.6L Pentastar. I found a video that Motor City Mechanic did about replacing the valve. His video tells you what you need to know and how best to accomplish the job. My motivation is twofold. First, the valve is...
