@Travis8352 since the FCA-PSA merger, things have changed.
@Travis8352 Same as Mobil 1 0/5W-20, it says that it's recommended for MS-6395 applications. This only goes to show that this entire non-sensical MS-6395 debacle was politically motivated.
No, it shouldn't. I'm willing to bet money that it's not going to do much of anything for the HEMI tick. The reason why Red Line works is because of the oil formulation. Below is a boring video. However, they explain it reasonably well starting around the 1:15 mark:
This is an older video released by Red Line but no longer available on the official website. However, it still valid today and makes for an easy digestion of...

Here is the thing: we don't know why they put 300ppm of Moly in there. It looks great on paper, however, we don't know what kind of Moly is and how it's bonded to the base oil.
Castrol for example uses a PAO molecule that they patented to bond additives to any base stock. Look up US patent 8,603,954. Something like that won't help a ticking HEMI. I'm betting that most ILSAC motor oils are made in a similar manner.
Mobil 1 FS 0W-40 uses an ester-based additive system. I'm willing to bet that Castrol EDGE 0W-40 doesn't. I tried the first one, it made the engine a bit quieter, but that's about it.
Lubegard? Well, when you add it at the recommended 3oz. per quart, you're displacing your other additive by 9.35%. Results are not guaranteed. It's a good cleaner though if you have a dirty engine.
So far, the only thing that improves the way a ticking HEMI sounds is Red Line. The logical explanation is that the esters bond to the surface of the metals inside the engine. Find me another commercially available motor oil that can do that and I could then say that we have a second option. Until then, we don't. I searched for a better oil for the HEMI, but there isn't one. It's either you run any regular oil, or you run Red Line.
I'm not going to experiment with other oils. When I switch from the 5W-20 that I'm running, my next oil will be Red Line. I will do a bit more testing before I do.
