All the oils bellow are blended without VII. You could say that the 5W-30 Euro is a better version of Red Line 5W-30 with a beefier additive package, POE, Esters, and AN. Come to think of it, it is better.
As how it's made without VII, it comes down to four simple letters: mPAO.

Only their non-VII line is. Their original lines do come with VII, the owner told us so - star polymer VII.

I posted about this - the non-VII 5W-30 is a heavy 5W in order to still call it a 5W. There is no free lunch in physics.

Hemi395 is running valvoline 0w20 right now
Would like to see what his take on it is. Seem like it is a better choice than Castrol in terms of the moly content - although I hear that Castrol's additives are more designed to protect the engine against wear differently. Seems like it has more moly than even PUP.

I will share it here to, so this is for my GMC Sierra 6.2 oil used castrol edge ow20 ep with only 1300 miles on the oil and total miles on the motor 2400, right now I have valvoline ep and right at 2k I will change it and send a sample to see if high moly oil will perform better, so stay tuned for that

Good post. Thanks for sharing.
I still believe think that issues with the tick has more to do with proper lubrication. I don't really think that there anything as a design flaw with the HEMI engine, but more of the fact that we're told to use thinner oils by the manufacturer (chasing better EPA).
As far as I've seen, those who stick to old school maintenance tactics and use thick oils like 5w30 or even 10W30/10w40 has great results without even needing any additives or special expensive oils.
Would using Redline 5w30 be a good choice? Absolutely. Maybe even using Redline 10w30 would be even better - depending on the climate you live.

He contradicts himself. You can't say "don't idle it" while also saying that lack of crank lubrication isn't an issue. If high idling hours was part of the problem, then that would only be the case because the crank isn't flinging enough oil at idle.

This is how the myth keeps growing. Guys on YT just running in circles contradicting themselves and each other.
I think you're right and I think many YouTubers who tackle this issue do it for views, including Uncle Tony and Reignited. To me it's a manufacturing related issue that can be kept at bay given proper maintenance. I'm not going to sleep over having to idle the engine to warm it up or spend stupid amounts of money on fancy engine oil. Though HPL sells proven products and they do work. Having Dr. leslie rudnick formulate their oils and working with the likes of NASCAR are some very strong credentials.

I dropped AMSOIL for good by the way. I could only take so much of that pamphlet culture, while not much money was coming my way.

Does that mean that you won't be using Amsoil anymore?

When I comes to the tick, I'm still convinced that the lifter tick isn't due to a design flaw, but a lubrication issue caused because manufacturers took the cheapest route better mileage and EPA ratings. GM, FCA (Stellantis) and even Ford are all guilty of this.
This is why this thread exists. To help us sort it out ourselves and the best lubrication for our engines.
There should be a better solution than asking users to use expensive oils in their engines. However, you can't ignore the fact that quite a few users on here will testify to the merits of using Redline. HPL does seem like an appealing alternative.
For me right now, the goal is prevention. The hope is that by using thicker oils from known brands like Pennzoil, Mobil, Valvoline or even Castrol and having shorter change intervals, will achieve this. For some users it does seem the case, although none of them face the hot weather that I do here in the Middle East (+49.C - over 50.C)
Right now I'm using Castrol Magnatec. I would like to get it tested and I'm looking into options for that.

no doubt and credibility went out door pretty much when he was referring to failed cams as what the hemis are known for.(not failed lifters being initial culprit) Also the fact of him saying then why does GM have same lifter failures? Yes they had/have ton of failed lifters but those were mostly due to subpar parts is why they actually came out with a bulletin about it, subpar parts getting subpar oiling. Dealerships have constant stock of the replacement lifters for this reason.

hes just another one that thinks as long as you keep up with maintenance using the recommended oil/filter and interval you will just be one of VERY rare that has issue.

You know what I find interesting is that GM actually admitted to the possibility of failed lifters due to insufficient oil during cold start. Hmmmmm

At least they admitted what Ram will not.

GM also has a very specific date range where it got really bad somewhere around 2021 or 2022, and surrounding that date there were less issues (but still there). According to gm forum anyway.

GM couldn't ignore the soft cam debacle of the early 80's, either because every small block cam got wiped out - couldn't hide it. I just tens of thousands of miles.

Went from carburizing to induction hardening cams to save money. Didn't get the hardening recipe right.

I remember cause fleets would say Mobil 1 was the cause.

Wouldn’t a design flaw affect every hemi ?
