The 10-48 is just the smaller version, most guys opt for the 20-820.

So the forum work on the 6.4 hemi tick obviously has been a little less then the 5.7, but we still have some good info as far as redline. The 5w40 redline is the preferred redline for top success rate, however if you are in snow state or area this may be some piston slap in the coldest periods, but it is one of those things, imo it is something you address IF if get the slap, the most important symptom is killing the hemi tick, piston slap is close to harmless. Two guys U@A and Tjelsimo (spelling) have had hemi tick with the 6.4, if you have question you know where you can find them, the dreading syn thread. They both tried many things.

Also, the 0w40 FCA recommends (PUP) has a viscosity at 13+ but in the engine spends most of it's life as a 5w30 due to quick shear. We know this for fact by uoa's, and we also know 5w30 redline doesn't shear hardly at all and hardly ever. So bottom line, the 5w30 redline would be "thicker" in use then the 0w40 srt oil. We also know 5w30 redline is a very special formula at combating tick, and will be thinner than your 40 weights in cold periods. Bottom line, if it were me, I wouldn't discount 5w30 redline with the 6.4, keep it for consideration.

There is a specific reason why manu's use 0w40 and not 5w30 or 5w40 or thicker. Because they want a 30 weight oil in use but they don't want the regulations that the 30 weight oils carry. We know this because virtually all 0w40 OTC oils are made on the thin side. they literally want this feature, if not they would have recommended and built 40 weight oils on the thicker side, but they didnt.
What regulations involve 30w oil?
