Dodge Durango 3.6L - second run of HPL 5w-20 - 18,700 miles on oil - filter pictures at 6,700 mile change interval run from 152,000-158,700 miles

Data can be fun, especially when you understand what it’s trying to tell you.
I wonder how your results will compared with HPL's own testing. Would they accept a sample from you to carry out their own analyses or testing. Just an idea!
What would they test that an independent lab hasn't already tested? There is a reason all samples get sent to Wearcheck, as they have no horse in the race. @High Performance Lubricants could do the tests in their lab, but insists an independent lab is used for UOAs.
The test results are only good as the equipment calibration and sample preparation.

I wonder is a bypass filter system would be inline for your application, something that filtered smaller particles and extended you main oil filter life? I have though of using one myself.
Hey now, I was joking!So much for those who theorized that the HPL was the source of that carbonaceous material...
Which brands?
His personal preference.
No, they have 5w20 HDEO in their lineup.
2016 Dodge Charger 3.6L 66,000 total miles 11,000 miles on HPL 5w-30 HDEO CJ-4
This sample was pulled from my 2016 Dodge Charger 3.6L with 66,000 total miles and 11,000 miles on the oil and 27.5 months in the sump and the consumption was zero. The oil filter was changed at 5,000 and 10,000 miles total, as the oil is cleaning carbon from the internals as we saw in my...

That was my thinking as well. In the ongoing use of HPL in my wife's Volvo XC (which is nearing 300,000 miles) I will continue to monitor/examine the filters at each change. I am curious to see when/if the carbon settles down as it has in Wayne's Durango.
The XC had a previous owner who changed it at the dealer until we bought it at 90,000 miles. The dealer, sadly, in those days, used bulk dino 5W30 (Castrol) which didn't meet specs. Many Volvos were ruined by Volvo NA not following the actual Volvo oil specs, and just using the 5W30 viscosity on an extended drain.
So, the engine in the Volvo had some deposits from that period in its life, and despite running on Mobil 0W40 and other Euro spec oils over the subsequent 200,000 miles, there are still some deposits in the engine. I suspect that it will take far longer to clean up than Wayne's Durango.
OI know you were, but there were serious comments in Wayne's previous thread that suggested HPL was the source of the carbon, and thus, the actual problem...
Agreed. Though similar equipment is used at HPL, their method for using them is more precise that what you get from common UOAs. They don't do used samples there for 3 good reasons. 1) They're busy with formula testing and adjusting, experimentation, and quality control so no time to run used samples. 2) They don't want to dirty up their equipment with used samples. (can't blame them) 3) They want to remain transparent through the process without any inclination of bias on their parts. In fact, when a UOA is sent to WearCheck with a CC to HPL, HPL doesn't receive the report until 5 hours after the customer received the report. The customer gets the results from the 3rd party lab before HPL does, just to ensure there's no bias in the process.
That said, HPL's blending equipment is more accurate, precise, and repeatable than any lab equipment. They've had to re-arrange their plant because the wind off the ceiling fan would throw off the scales on their 8,000 gallon blending tanks.

Are you able to get a copy of the test/ analyses or is it a petroleum institute procedure.
OH, c'mon now!
WWilson: I can’t find their 5w20 HDEO. I’ll keep looking.
@High Performance Lubricants can tell us where to find it.
Call them. Talk to Mary Jane. There are often products they make (like a 75W gear oil, suitable for Toyota transfer cases, or manual transmissions) that aren’t listed on the website.
So, call.
