Any Pentastar V6 UOA's available?

(I looked back some and did not see any)

Oil was Rotella Gas Truck 5W-20

why I don't like the idea of early uoa's, the engine is too young to be helpful and those wear numbers are not indicative of how the engine is wearing. I would just wait a while, I bet you will be happy with the results if you do,.

I don't feel bad about the sample since it is pretty early on. Hopefully they keep getting better with every change and copper goes down...then I will feel really good about it!!

Only went 4648 miles and will usually be going around 6k or so. Think it looks pretty good for current mileage on the engine.

Burla · Jun 23, 2022

Looks good, was there a reason you used high mileage oil with only 20k miles? Maybe we all should consider it because that looks like a nice additive package for a hemi. great moly there. Do you use different oils at times or always that one?

Would the conditioning of seals that early on possibly be counter productive? Really don’t know just asking the question.

It looked like the add pack was a bit more robust in a VOA I saw and the high mileage version of Valvoline has gotten consistent rave reviews. But I can only say looked because I am neither a chemist nor a petroleum engineer. I have used this oil from the start a long with the high end Fram filter.

Somewhere, somehow Valvoline has said HM versions can be used at any mileage. I don't remember exactly where I read that, however.

machinelube HM oils

They say the same thing about ester based oil and pao oil, but I have over a decade on it and no seal leakage at all, never seal material in the filter. I was being a little facetious or quib when I said that, I actually try and avoid HM oils just from old school opinions not based on facts, but I do appreciate that specific one and do like the moly. That was the proper response to whether or not to use a HM not my quib joke. Thanks for posting that, I say look what ML says and research it if you want to run HM oil.

How long before getting the results in and do they send physically in mail or email you a copy? I sent off the sample last week so waiting for results.

Burla · Jul 11, 2022

They give you a hard copy once, then the rest online unless you order hard copy. Depends on the post office, 1 week to 2 weeks, it is very rare over two weeks.

Just got my blackstone results, QSFS 5w30 and 15oz lubegard, oil before was QSUD 5w20. Hope its clear enough for ya.

Wow look at the moly!

Wear numbers look great for that low mileage too

despite wear being low, it is getting lower as you are going, and despite it being so young. Yes wear usually gets better, but usually isnt that low imo. Looks like one of those million mile hemi's on paper. Maybe the extra viscosity is helping as well. One of these days someone will go back to 5w20 to possible disprove this.

Cableman · Jul 13, 2022

Ill keep this 5w30 qsfs and lubegard combo going, cant complain and its quiet.
Have a 2k trip coming up in August, prolly go 6k on this oci.

Burla · Jul 13, 2022

Not only moly which is great, but I love what lubegard does to phos and zddp, just boosts them 100ppm or so, very nice additive. The single thing I dont prefer with redline is the zinc level, I do prefer these levels, just a bit above api. I don't think zddp is any answer for the hemi, but I do think api is a little low, so this is a nice middle ground additive. If it aint broke don't fix this one.

Nice combo & results! Drive 'uninhibited'...

I've not run 5w20 since 75k miles.

Nothing has changed, strategy wise, since I switched to Castrol, MOS2, and SRT filter at 75k miles. The only thing changed, literally, is time of year the sample was taken.

That wouldnt increase iron, once iron wear is created it doesnt go away. That is a thin 5w30 as it is in the 9's. So something in that engine is off. Not only iron wear up substantially but viscosity is shredding more then the prior two, especially if that is the same oil in last 3 runs, the other two runs oil was in the 10's visc.

Here's the latest, another 5k OCI. Zero change in strategy. Iron dropped. I will be very curious to see if my next winter oil change has higher iron again, as I am sticking to my thought that my prior sample was the first sample that had cold weather starts on it.
