What do you guys think of this report? First off, the oil in this sample is HPL with boosted technology (Silver Bottle). The description is incorrect. The previous oil that was drained (sample 1) was Driven DP40. This sample (HPL 5w-40), was flagged for high oxidation. Could this be a result of the HPL w/boosted technology not playing well with the little bit of left over DP40 from the prior fill? Something else? For what it’s worth, the Silver bottle HPL has been drained and replaced with High Performance Lubricants Cold Climate 5w-40. Truck is deleted and gets driven on the weekends. Sometimes shorter trips not quite reaching operating temp. Northern IN.

Silver bottle.
Sounds like HPL HPL.
NOT High Performance Lubricants HPL.
It’s still technically HPL, but like the Warren Distribution leg of HPL.

All joking aside, neither Harry Hruska nor David Ward are going to put their hard-fought reputations on a pile of garbage; just understand that Harry’s HPL has a slightly different focus than “our” HPL. They’re both top-tier oils, though.

Oxidation is from esters in your case. Try using WearCheck in NC, that knows the baselines for those oils and won’t flag stuff that’s perfectly fine!

The HPL (High Performance Lubricants HPL) HDEO CC 5W-40 has a baseline oxidation value of 36. When you run your next UOA this will get flagged but you should subtract the VOA sample of 36 from your UOA to figure out how much oxidation has occurred.

I posted the VOA for the HDEO CC 5W-40 a few months ago & it's also listed on the HDEO VOA database in the VOA forum.

If I subtract 36, I would get -9? Why does it have such a high value to start with? Could this mean that this oil doesn’t do as good of a job at keeping the engine clean as some others? Appreciate the info. I’m on the quest to find the best protecting oil for my application.
 
The virgin oxidation is ~22 for that oil so you're looking at a relative oxidation of ~5.

Everything looks great. I would shoot for 10,000 miles this next sample and keep extending it. This oil is so minimally depleted at this point, you could almost still call it a virgin sample. It's just rounded second base.

Great to hear this. So what causes the higher oxidation levels from the get go? And does this mean that this oil is possibly not doing as good of a job at keeping the engine as clean as other oils? I change it once a year in the spring, usually has between 5500-6500 miles. Thank you

Again, since it was overlooked above:
“Oxidation is from esters in your case. Try using WearCheck in NC, that knows the baselines for those oils and won’t flag stuff that’s perfectly fine!”

You stated this sample was the "grey bottle" HPL with "boosted technology". That isn't the High Performance Lubricants HDEO CC 5W-40.

It sounds like you used a version, that's made by High Performance Lubricants for Precision Turbo, that looks like this(in a different viscosity:

What you put in for the current run, and what will be on the next UOA, should be this:

The bottom one is the HPL spoken of in 99% of threads here & the one I ran the VOA on and referenced earlier.

This is correct sir.
 
This is correct sir.
So the oil that's currently in your rig has a virgin oxidation value of 36. When you do your next UOA the value will be something above 36 as that's the baseline. Whatever the delta is between 36 & your UOA will be amount of oxidation that has occurred while in service in your rig. (y)

Perfect. With the oxidation being higher due to ester, does this mean that this oil is potentially not as good as others at keeping the engine clean?

No, quite the opposite in this case. Not all high oxidation value oils are cleaning oils as there's different types of Group V oils and not all of them clean well. HPL's oils are known for cleaning & conditioning due to their particular chemistry.
