YouTube UOA Testing of Amsoil SS vs Penzoil Ultra Platinum on Ram 2500 w/6.4L HEMI

[rstcso]

This YouTuber started UOA testing using the OEM fill using PUP 0W-40. After several OCIs, did a flush interval with Amsoil SS 0W-40, then sent the next two samples for UOA. He then did a flush interval using the PUP, and sent the next sample for UOA testing. He has LSJr on his channel discussing the results, but you can take a quick look at the UOA results and see which oil is better for his engine and how he uses it. The discussion goes into details on why the results may be as they are on his HEMI engine,

It makes me question whether I should have stuck with the Honda OEM oil for more UOA data points before switching so quickly to Amsoil SS. I might have gone back to the OEM oil for more testing, but I have four cases of HPL PPPCMO waiting to be switched from the Amsoil after this OCI.

So all the wear metals are within a couple ppm of each other except copper. Is it possible the high solvency esters in Amsoil are reacting with copper or cleaning?

I’m not sure we have enough data to determine a trend with one oil or another.

The copper would react with the ester base in Amsoil.

Did he explain the viscosity of the Amsoil? Seems like a lab error. I've never seen Amsoil 0w40 end up as a 8.8. And fuel is only 1.1% so it's not the oil.

It’s got to be an error. The sample before is 13.6.

The reaction between the esters and copper was was his hypothesis, also. He said the HEMI engines typically have high copper levels compared to others and might have something to do with copper used is VVT (or something else, which I don't remember), but doesn't seem to effect the longevity of the engines.

Didn't mention viscosity discrepancies. I'm on my small MacBook at the moment and can't see details very clearly. Thank you @rijndael for capturing and posting the results. At least now I can see it.

Seems SD reports have more and more errors and is why I'm switching to WearCheck.

I cannot stress this enough ....

Singular UOAs (and small sample sets) are NOT, IN ANY WAY, a means of comparing/contrasting anything. To make any conclusions of the superiority of lubes based on a couple of UOAs is foolish. Doing a few "flush runs" may help normalize the chemistry in the sump by reducing residual oil from a previous run, but it does not present enough data to understand "normal" (statistically reliable) performance.

The comments LSJr. makes leads one to believe that these are logical conclusions. Nothing could be further from the truth. He may be a trained tribologist (debatable), but he is most certainly ignorant when it comes to the world of proper data-driven analysis.

I'm disappointed that vehicle mileage isn't on the report, unless I'm missing it somewhere, it looks to be just service interval mileage. I'm assuming by the OP that this is a brand new engine. If so, why in the world are we starting to compare wear metals when the engine isn't even wore in yet?

I offer up my truck with a similar engine as some information. Full disclosure, it's a highway queen that will haul junk to the dump or a few thousand pound trailer periodically. It's the family hauler for our family of five on the daily, road trips, etc. With the exception of the 5/10/24 UOA, I run a flush interval before sampling, I was just too curious to not do a UOA at that time.

This is the second OCI of switching back to HPLs standard Passenger Car Engine Oil. These two OCIs were with 5w30 instead of the 5w20 that I used in 2023. I've owned the truck since 8800 miles and have followed the OLM with synthetics since then.

I'm really liking this report with a couple of asterisks. I asked for GC specifically, provided them starting oxidation so the only thing flagged was water but it was flagged green. Filter is a Carquest Premium Blue.

Iron as mellowed out nicely and does coincide with the HPL switch, which is interesting. Copper has mellowed as well. Aluminum is...

Iron as mellowed out nicely and does coincide with the HPL switch, which is interesting. Copper has mellowed as well. Aluminum is consistent.

My intention is to change the filter, top off and take this to 15,000 miles. Not sure if I'll sample and change, or sample and run it to 20k accordingly.

Fuel dilution and water. Never had water registered on a UOA before. The sample was taken after driving home from work, so it was fully hot. It sat for 10 min or so before I drew the sample through the dipstick tube. I know the weather was stupid humid and it was starting to rain. I thought I took care in that fact, but maybe I didn't. I drew the sample, capped the bottle and put it in the truck. Is it possible this is just condensation from the weather and heat of the oil?

Last GC fuel reading was .6 % so it's definitely higher than that reading. My idle hours are up a bit for this CI Is this even something to think about or just take another sample at the oil change and see what it is and go from there?

I can't imagine picking the "best oil" for my engine based on a YouTube video.

But that may just be me.

I’m not sure we have enough data to determine a trend with one oil or another.

For some reason, this thread reminded me of this cartoon:

 

[Hohn]

We're not going to push back on the assertion that 0w-40 PUP is the OEM Ram oil? I'm *highly* skeptical of that claim.

 

[Pablo]

Did he explain the viscosity of the Amsoil? Seems like a lab error. I've never seen Amsoil 0w40 end up as a 8.8. And fuel is only 1.1% so it's not the oil.

That's messed up.

I'm not watching a 39 minute video. What was Lspeed's conclusion?

you can take a quick look at the UOA results and see which oil is better for his engine

I really want to know how you can see this.

And the answer is, you cannot. This is basic but the alure is strong on this one.

Redline and HPL also see high spikes in copper the first time they're used in a ram/hemi, subsequent runs always end up with lower amounts.

Post in thread '2019 RAM 1500 Sport 5.7L - HPL "overkill" 0W-20 10,876km'

Aug 16, 2023

Am I reading this right? Copper is 5.16ppm per 1000 miles on the M1 sample, but 12.73ppm per 1000 miles on the HPL?

Copper is high for the run & Mobil is showing almost x3 times lower wear on the previous sample.

The copper isn't from wear. This is leaching of copper oxides from cleaning action. It settles down with subsequent samples.

If you were to take a penny, place it in a highly polar ester, heat it to ~200°F for several hours, and then sample the ester, ICP would show a lot of copper and zinc even though no abrasion nor corrosion is happening.

They 100% botched the viscosity on the Amsoil somehow. Speed does use different equipment that measures metals differently, but this viscosity is clearly an error.

Now that I'm reading all the comments, the only conclusion I can come to is ignorance and stupidity on my part.

 

[OFFRD]

So you guys are asserting that maybe 10 or 20 oil cycles on each oil would be needed to get a clear picture of how the engine reacts to each?

I'm not a tribologist, but I did stay at a Holiday Inn Express last night, (and I have a science background with statistics and data analysis in my transcript) and I strongly disagree.

Seems SD reports have more and more errors and is why I'm switching to WearCheck.

In another thread you said you weren't going to do any more particle counts with SD since they always seem to have the exact same ISO codes. Just FYI, WearCheck seems to do a good job with particle counts.
