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...

So far, nothing to worry about. The wear rates are very good. The uptick in Al and Pb may just be incidental; best to just stay the course and see where they fall next time.

The correlation between oxidation (pending verification) and vis increase may or may not be of interest, depending upon the results of the updated ox value.

You had been doing UOAs about every 6k"ish" miles, and then went 9k miles this time. Was that just a fluke or planned? As the OCI matures, I would recommend keeping an eye on it; perhaps every 5-6k miles.

This is exactly the kind of performance I'd expect out of HPL!


At some point, I'd think considering BP filtration would be an excellent move.

I just didn't get around to sending a sample in.

Someone would really have to twist my arm to get me to install a by-pass setup.
 
Hola My friend,

I got some good friends in Naperville. I'll be incline to change just like the comment from Overfill. If we get one those cold winters, I wonder what the oil will be at -10 below.
 
Lead at 3 ppm seems like a statistically significant increase considering it's been 0-1 for the previous ten UOAs. I'm not sure if that should be concerning, but it'll be interesting to see if it's increased further at the next UOA.
 
Interesting how wear materials measurements trend up and down on the same oil over time. I'd imagine how much measured deviation we would get as more of the same oil gets sampled overtime. Would it make a nice statistical study and shows there is noise going on?

Keep in mind that there are three drains in this table. Each is highlighted in a unique color. The short middle drain was a very short drain to get the old CJ-4 formula out.

Interesting that copper has sort of plateau'd.

Since it has gone up two grades, I'd be inclined to change it personally, just based on that fact (the oxidative thickening) but I understand your reluctance to, based on the health of the lubricant and remaining TBN.

“TBN doesn’t matter anymore these days, nobody cares about it, blah blah yada yada”

But now all the sudden, “oh lookie at all that remaining TBN 😍🤪”
