Moly content?

If I'm remembering correctly:

Synthetic- Quaker State Ultimate Durability (Certain Idemitsu blends have much higher Mo, but I've not found them "off the shelf"- they are easier to find if you're willing to go to a 0W-20).

Conventional- Pennzoil

I was also interested in such an oil (high moly) and was planning to do some research.

In my case, a substitute for TGMO which has high amount of moly ... that I can buy from store as oppose to dealership.

Like op I also have a 5.7L but it's a Tundra.
Maybe 5.7L trucks like extra moly ... lol

Check the Virgin Oil Analysis Board Room. I'll bet the SOPUS Family of Pennzoil, Quaker State, Formula Shell and Rotella has the most Moly content overall.
 
For everyone suggesting a 0W-20 oil:

I'm pretty sure he's looking for the highest moly content in an oil that is within the specs listed in his owner's manual for warranty purposes. A 0W-20 oil's moly content does not help him here.
 
The moly that is used in the Idemitsu oil is not the same formulation that you will find in Shell or Valvoline or Mobil. One cannot go by ppm counts of moly in this respect.

Use a major brand of oil that meets the specs and rest easy.

The 5.7 HEMI has had a somewhat higher than average failure rate of cam lobe problems over the years. 99% of the problem is with the metallurgy. A common theme when looking at 5.7 HEMI cam lobe failures is the use of low to no moly oils.

Not sure how important the W rating is to the engine as long as at the running viscosity is correct and the start temp window works.

So if it's the "0W vs 5W" standing in the way I wouldn't let that be a gate.

Idemitsu is an excellent oil company, but I remember this particular noack being higher than Id like.
In that you can actually tell anything by that lone parameter.

Exactly. Thank you. I have a lifter tick on start up that goes away after a few seconds, looking for something that I can buy off the shelf that has a high moly content.

Were these cam failures not related to much earlier year Hemis? I thought I read it was the 2011 models mostly?

I don't know with 100% certainty, maybe Overkill can comment, but I think these cam/lifter failures are pretty much a thing of the past?

From what I have read on Ramforumz, the newer Eagle Hemi like mine does not seem to have this issue.

Not disagreeing with you. That said, while a 0W would do just fine, for warranty purposes he would probably like to have receipts stating that he bought the correct specced oil. Yes, NOACK is at 14% so there are probably better options out there.
