How would a greenhorn distinguish piston slap from a bad lifter tick?

Piston slap only happens when cold, the pistons shrunk more then the block, metal shrinks in cold. If you ever have warm piston slap, you have some real issues.

The dangerous tick is warm idle lifter tick, if it ticks when oil and engine is warm.

so what flavor of mobil 1 is everyone using EP ? I am reading good things about EP flavor
Mobil 1 EP is excellent motor oil. For the price, it doesn't get any better.

It went OK, wasn't super rattley/noisy but both RL and HPL are quieter.
It's not possible to hear an audible difference by switching from one oil to the other. It's called cognitive bias.

Try this experiment:

Put HPL or Red Line in your HEMI. Let three or four of your friends listen to it running. Then change the oil to Mobil 1 FS 0W-40. Ask the same people to listen to it again and suggest to them that the engine is now quieter on this oil and ask them if they think it is.

It's called cognitive bias and everyone does it. On forums people do it to each other all the time.

At the end of the day, if HPL or Red Line makes you feel better, then it's worth every penny. That's all that counts.

The UOA looked pretty good:
Looking at your Blackstone UOA, Red Line didn't perform any better or worse than Mobil 1 FS 0W-40 in your HEMI. That means that the HEMI is an engine that just needs good clean oil and a decent filter, and sane OCIs to run for a very long time. Provided you didn't get a batch of bad lifters, of course.

I just prefer an oil that has everything in it instead of having to add LG or whatever
Lubegard BioTech is not an additive snake-oil, it's a mild top treatment for your motor oil. In practice it ads a negligible amount of improvement, if any, to an already awesome motor oil - Mobil 1 FS 0W-40.

I like how quiet it's now running too since switching to HPL.
I hope you realize that HPL motor oils are formulated by the same person who formulated many of the oils that Mobil is selling, including Mobil 1 FS 0W-40. HPL is very good oil, but it can't make your engine sound any different than Mobil 1 or any other oil. You'd need to go down to using something else than motor oil to get a HEMI to sound any different. A HEMI has large noisy rocker arms and noisy injectors, so people think the hear all kinds of stuff when they listen to it. It's trashy, but by no means is it a bad engine.

What facts do you have to back up the claim that Blackstone UOA's are full of inaccuracies?
Blackstone is unable to measure fuel dilution. They have a history of giving bad advice in those "interpretations" they write. A real tribologist should write those notes, not the lab assistant that ran the sample.

They guestimate fuel dilution by the flashpoint that's also no accurately measure by them. It beats me how they can mess that one up. Finally, their viscosity measurements are also all over the place. At least their spectrographic analysis okay. However, sometimes they mix up the samples and you end up getting the results from someone else, with comments that apply to your vehicle.

Unfortunately we're not allowed to post links to other forums. Google some of the things I mentioned and you will easily find the test results, including the humorous apologies from Blackstone for when they mixed up customers' results.

Oil Analyzers is owned by Amsoil so there's that...
Nope, they're not owned by AMSOIL. Oil Analyzers is Polaris Labs. AMSOIL just like to put their brand on the kits they re-sell, just like on everything else they do. Do you really think that AMSOIL blends their own oil? Nope, they don't, especially their API licensed and the Euro oils they sell. All of that is shipped to them by rail and all they do is put it in bottles with their name on it. It's marketing at its finest. Anyway, it's harder to get a Polaris Labs account. Oil Analyzers is cheaper, and the sample goes straight to Polaris. Also, it would foolish for AMSOIL to tamper with customes' oil samples or results. Don't you think?

The dangerous tick is warm idle lifter tick, if it ticks when oil and engine is warm.
What causes that warm idle tick?

One of my hobbies is high end audio, I'm well aware of confirmation bias. I do however have very good ears. Not only can I hear it, you yourself can actually hear it too on several YT videos floating around comparing the engine noise running one oile (I believe it was amsoil) vs Redline.

I suggest you dig deep down for some humility and try your own experiments, you may actually learn something!

Some people are only ever going to hear what they want and not actual fact. Not worth the energy it takes to try and steer them otherwise.

weird one, silicone and aluminum in base visc 6 and nothing else. Some silicones have some type of plating effect, but I'm sure this would mess up your wear portion of your uoa. It is not only this one, but a couple more aluminum motor oil additives out there. I have no opinion on it at this point. I would be curious to micron ratings.

3.6
I know for a fact that Castrol Magnatec 5w20 ran much quieter than Castrol Edge 5w20 in my wife's Ford Edge with a 3.5 engine.

It was noticeable as soon as I started the car, and every time I heard it running. The valve train clatter was louder.

I'm still running Edge, on the second oil change with it. I would go back to Magnatech, if Castrol still made it.

I've read that the GTX in a white bottle is the old Magnatec. But, it doesn't say anywhere on the bottle about the "intelligent molecule" Magnatech had, whatever that was.

I have two gallons of PUP 5w30 arriving today for the 3.6 in my Ram. I have never in my life put Pennzoil in anything. You couldn't have paid me to put it in anything back in the 70's when it clogged engines up so badly. But, the technology in the PUP, the UOAs I have read about it, and YouTube head to head test with PUP have convinced me to try it.

I went 5w30 because the VOAs I saw shows PUP to be blended on the low side of its rated viscosity, so 5w30 will likely end up as a high 20w. At least that's my thinking.

These 3.6 engines with the electric fans that don't come on enough to cool down the engine until 220 degrees also factored into my decision to go with a 5w30. Plus, the owners manual reads that 5w30 is fine.
