2019 Ram 1500 Classic 5.7L - HPL PCEO 5w20 - 9709 miles

[racer12306]

History: I've owned this truck since 8848 miles in June 2020. I've followed the OLM it's entire life, except for scheduling issues. This interval had the OLM at 5%. Commute is 80% highway. Almost all family driving is in this truck as well on evenings and weekends.

In went HPL Euro and a Fram Endurance in the standard size, wasn't a fan of how the fat one fit.

Iron is way down, copper is up a tick from last time. TBN is still very strong at 6.6. Viscosity is up from a base of 8.8. Don't know the base oxidation of this oil but we know HPLs are elevated from "normal" oils.

Others may have some more insight on the Copper, w/this engine, but everything else looks good. The viscosity did well for a 5w-20 & the mileage.

I looked over my oxidation data on HPL oils and my guess is that your oil started at about 30, so the normalized oxidation of your oil is approximately 4. We also know from lab data that HPL oils have extreme oxidative stability, so there is nothing to worry about there.

Everything is fine. A shear stable oil is only going to go up in viscosity but this increase is minimal. Do we know the virgin oxidation value of the HPL line? If it's 30, then it's perfectly fine.

That's a good looking report. The base oxidation value is ~30 so you're good to go there. The viscosity has thickened a tad into the bottom of 30 grade range which isn't a bad thing. The TBN is still looking good.

The copper is likely a result of chelation. The strong cleaning action of that oil is removing layers of copper sulfide. This is quite common and should settle after a few changes.

I would go for 15k miles on the next change.

I thought I remember reading about chelation. This was the 2nd change with the PCEO 5w20.

I switched oils to the Euro 5w30. I've got another change worth of that, debating on sampling a time or two on this change or just use it as a "flush" change for 10k and then start sampling on the next change.

This thread suggests that the starting oxidation is lower than 30, maybe 20? The Euro is 20.

This is @High Performance Lubricants' entry-level PCEO 5W20. Lots of short trips - most trips are under 5 miles. I doubt the engine oil gets very warm in a hybrid engine used for this type of service. The oil was in use for 10 months. Elevated Silicon is probably from RTV; the timing cover and...

25-30 range I think.

I assume Sample #2 was a VOA of some sort?

Yes, the Euro 5w30, it’s also in the VOA section.

 

[Brons2]

Looking good, TBN strong at above 6, almost what many SP oils start at. You can probably reset the oil life thingy and run it down to 15% again.

Ahh never mind
